Shadar kai 13 rog, 5 wiz, 2 ftr thrower build - input please

[Klixen]

Trying to get some shadar kai IPLs with a new kind of playing style - I've done casters, melee and monkchers and am looking to try out a thrower build.

Basically Shadar-Kai required for the PL, 13 rogue for two specialties, 5 wiz for EK tensers (since BAB is awesome for speed throwing), 2 ftr for a couple of extra feats.

Not really attached to the build I've come up with below, so any critique would be great (classes, split, feats, etc - all are up for change). I will probably have missed tons of obvious stuff, since this is my first attempt at a thrower build ever.

Going INT based with goodies from harper tree, EK and mechanic - Harper is not in this version of the char planner, but right now is expected to be 28 APs with the following distribution:

Cores 1-4 (6)
T1: Tough (1), Harper enhancement (2), Strategic combat 1 (2)
T2: KtA (3), Versatile Adept 1 (3)
T3: Int (2), Versatile Adept2 (3)
T4: Vigor of Life (2), Int (2), Versatile adept3 (2)

Planner output below (max INT, max CON, levelups into INT)

I just have two critiques: you have half a point in Concentration which isn't going to help you at all; I'd throw that somewhere else. I'm also not certain you really want the Medium Armor enhancement in the Eldritch Knight tree. Unless you think you really need the extra -5% ASF chance, medium armor won't work with your Improved Evasion, and those 2 points could probably be used somewhere else.
Looking at the enhancments overall, I'd drop Medium Armor prof and T3 Crossbow Training and spend those four points on the last core Shadar-Kai, wand and scroll mastery in EK (to be able to still get Tenser's), and UMD. You could then run with leather armor without worrying about ASF and the quality of life improvements from more invisibility, more successful and better UMD's should outweigh +1 to hit and damage.

[Thalone]

Can't tell why you're taking Quicken/Extend for your Wizard freebies. Won't (Improved) Mental Toughness at least give you SP to Cocoon?

Looks like you took weapon proficiency really late... were you doing a different fighting style prior to level 24, or throwing different weapons?

You are obviously right about the half concentration - I would use that point in another skill. This was the first iteration of the build and I didn't count ahead with the skill points.

The EK points were just thrown in to allow for TT not for Medium Armor Prof. I suppose I could change those to WSM instead without losing anything.

Thanks.

Quicking/Extend is for casting TT in combat and for it to last longer (along with displacement and haste, if I have the SP) - between 120 from past lives and a Power item/augment and the five levels worth of wizard, I am not sure if I need any more SPs, I guess it is one of those thing that I wont know for sure until I try.

If you are making a thrower build who is NOT using shuriken, Swashbuckler is about a zillion times better than Eldritch Knight (even though the crit multiplier bonus still doesn't work, AFAIK). And if you are making a shuriken build, you really want the extra proc chances from Adv Ninja Training (monk 3) and possibly 10K Stars (monk 6).

Thanks for commenting.

So if I plan to use a shuriken I should go at least splash enough monk for 10k stars and shuriken expertise - this is better than the faster throwing speed of full BAB? Full DEX and WIS build then? I have a Morning Star and enough materials to craft TF Tier 2.

If I plan to not use a shuriken, then go with a bard swashbuckling cannoneer throwing TF axes or daggers from level 22 up?

Any good posts on splits for these builds? I would like to keep the rogue (Shadar Kai), but the split classes are not set in stone.

Mind, I am probably only going to use this for IPLs, doing a IR once at level 28, so no use being awesome xp at 28 and bad before then

[Saekee]

Forum users Jakeleela and Tilomere were posting a lot of thrower builds (see meteor shower, tinkerhell and critzilla). With U25, the mechanic core level 18 adds significantly to the weapon crit multiplier. So I would build around that--maybe 2 arti for rune arm use, go INT, use Harper KtA and of course tier 5 mechanic. The capstone does not seem to benefit thrown weapons much.
Consider the nightforge spike as your key weapon. It has an awesome crit range and multiplier. It will not be great DPS but it sounds like you want a flavor build? With mechanic you can also drop web traps and be a stealthy demolitionist.

There are others with more experience with shuriken builds than me. A few builds to consider:

I'm not sure any of these have been updated for Mechanic changes, though.

I suspect rog / bard / rgr (Mechanic / Swashbuckler / DWS) is the best overall combo for a non-centered thrower build; I just haven't decided what the best class split & Enhancement spread is.

[Firewall]

I have heard that they fixed the Crit Multiplier from Swashbuckling. I didn't test it myself yet though. The problem with being Shadar-Kai is that you cannot take DEX to damage if you don't have either halfling or a monk level. Because as far as i know they still have not fixed Swift Strikes from the Swashbuckler tree to work with throwing weapons. So that would either rule out Shadar-Kai or Swashbuckler.

So being Shadar-Kai i would advise to take 3 levels of monk and be centered to get DEX to damage and Ninja Training II. If you are centered and use shuriken you should also have the Shuriken Expertise feat.


If you go mainly rogue with the changes to Sneak Attack damage scaling with 150% ranged power i would advise at least 12 levels of rogue for the epic Improved Sneak Attack feat (which is missing in your build).

If you take ranger levels DWS is nice for ranger feats, SA damage and Favored Enemies as well as improved SA range.

If you take 14 levels of paladin you can take the Holy Sword spell for enhanced crit range and multiplier.


So if you want to have DEX to damage as Shadar-Kai that leaves something like 14Pal/3Monk/3X or 12rogue/3monk/5X on the table. For X you could probably choose 3 monk for 10k stars if you get enough WIS or some ranger or rogue levels.

I agree with unbongwah that rogue/bard/ranger would be a powerful SA build but you would have to be halfling for DEX to damage. I'm personally not a fan of high Sneak Attack-depending throwers because SA range - where you will do most of your damage - is quite short for a ranged build and you have to divert aggro and circumvent fortification all the time to do any SA damage. But that's just me.

[unbongwah]

I have heard that they fixed the Crit Multiplier from Swashbuckling.

It's still on the Known Issues list: "The Swashbuckler stance is not applying its +1 Critical multiplier to thrown weapons."

Because as far as i know they still have not fixed Swift Strikes from the Swashbuckler tree to work with throwing weapons.

AFAIK, Different Tack only applying to SWF is WAI, not a bug. It just sucks that your options for DEX- or INT-based throwers are so limited.

If you take 14 levels of paladin you can take the Holy Sword spell for enhanced crit range and multiplier.

AFAICT, Holy Sword's crit multiplier also doesn't apply to throwing weapons.

[Firewall]

I know it is still on the Known Issues list but still there are people reporting it as a hidden fix. I can't say for sure because i haven't tested it on Lamannia yet. If they fixed the crit multiplier for throwers that would most likely be true for the Holy Sword multiplier too. Maybe someone can test it and report it here.

Different Tack not working with throwing weapons may be a bug or not but they should word it correctly if it is not...and in any case as far as i know the only ways to have DEX to damage are halfling or monk.

[Firewall]

To finish brainstorming you could also make a 20 monk Shuricannon 2.0 (see my Signature) but that would cost you a LR+1 Heart. You would only need to exchange the lvl 1 Dodge feat for the Shuriken Expertise feat. I posted a heavy DPS variant that goes deeply into the Harper tree with Tier 5 harper enhancements and neglects the Racial and Henshin tree at the cost of 1 point of passive Ki regeneration.

I personally plan for my Shadar-Kai iconic past lifes going as either 15Paladin/3Monk/2Rogue or 14Paladin/3Monk/3Rogue centered shuriken build.

[Illethian]

Im currently running a shadarkai 12 monk 5 wiz 3 rogue shuriken build that's a lot of fun. 31 EK (6 dex) 24 HA (4 dex) 6 NA (for obvious reasons) and the rest in TA for another 5 dex. Water stance gets you passive regen and go high on the concentration. Get as many on hit proc items as you can stand (frozen tunic or cloak of ice, ring of slayer (?), celestia or day star if you dont have it and the spell touch shuriken's with paraliza (imp for higher lvls). With IPS and imp paralyze the group will thank you though dont expect IPS before lvl 18. You want high dex but dont overlook wisdom for your 10k stars. 42 wis will get you 78% and 28% and 1% for extra throws. Stay in water stance to make sure you are recovering your ki or else youll find run out rather quickly because your AP on this build doesnt allow for Henshin. The NA stealth tier 1 will get u a bit more if you wanna hang out in stealth to regen. Razor is a nice offhand for heroic lvls until you get something celestia. I see upgraded TOEE items can give greater firey detonation but have yet to get one to test for procs. Hope this helps. Very fun build. You can always ditch HA for more NA or henshin but a shuriken thrower is all about the dex to get the extra shuriken. Im chunking 4 stars easily with a 28% chance on a 5th.

[Illethian]

On a totally off hand shadar kai build 13 rogue 3 bard 2 ftr INT based heavy Harper agent is nice dps Sorry but your build reminds me of it.

[elcagador]

This is theory and I don't know if swashbuckler enhancements and dashing scoundrel stacks with mechanic, if they do then you can have:

- T5 mechanic for fletching, rapid fire, mech reloader, leg shot, sharpshooter, point blank range, etc,
- T3 swashbuckler for +2 crit range, +1 crit mult with shuriken, +11% doubleshot and +6 dmg, +30 action boost doubleshot
- T4 assasin, venomed blades, sa, dmg boost, killer
- Able to cast extended tenser spell with 12 arti levels or scroll it if mostly rogue lvls for imp sa dmg.
- running speed with rogue and bard lvls
- Harper for kta
- Int to dmg with harper or mechanic (if 12 rogue lvls) or dex to dmg with halfling using 16 ap (at the cost of some assasin ap)
Race drow for free shuriken expertise feat, or halfing if no other source of dex to dmg, or shadar kai or any.

Lose advanced ninja training but can keep a very high sustained doubleshot, like 11 (swash and scoundrel)+ 10 rapid fire + 10 (feat)+ 2 (ship)+ 8 (item)+ 9 (past lifes)= 50 permanent doubleshot + 20 (killer)= 70 sustained doubleshot+ 30 action boost= 100 doubleshot in dreadnought destiny

That with +2 crit range, +1 crit mult, 20 ranged power, +12 dmg + 70 ranged power from blitz and some sa dmg.


have the option of taking more bard lvls for extended haste and displacement at the cost of having to scroll tenser.

Edit:
After looking at enhancements, I would try with 13 rogue levels for more sa dmg, possibly defensive roll and imp evasion, int to dmg with mechanic core, that way can do some ap distribution like 36 ap on mechanic, 11 ap swashbuckler , 23 assasin (killer), 7 harper (kta), 3 acrobat (run speed) and can take any race. (another option is giving up some assasin ap for more harper, mech an swash) So could be a
13 Rogue/3 bard/4 fighter (extra feats) or barb (run speed), etc.

stats: high dex for extra shuriken chance and int for dmg.

I am thinking of a 12/5/3 Arti/Rog/Bard Halfling
It was between 11 wiz and 12 arti, but in the end 12 arti gives me those 3 needed feat slots since you are neither monk nor drow.
Also going on that Armor of Speed is like haste and can cast Tenser's Transformation without swapping over to my scroll.

Enhancement split:
12 into Halfling for Dex to Dmg
11 into Swash for Swashing Style pick one idk want to be dashing or a cannon
22 into Harper for Four Dex Bonus'
36 into Mechanic for T5 not sure if Mech Alacrity stacks with haste or armor of speed, but 10 Ranged Power

However, if you notice its a 81 AP build, so close to getting everything I want...

Not a big deal, can take less harper and 37 ap in mechanic for sharpshooter t5, and take full doubleshot action boost in swashbuckler (13 ap), and 18 ap on harper.
Your build seems cool, no room for killer (20% doubleshot), lose some sa dmg, but get more use of tenser and a bit more base dmg from being dex to dmg with a bit higher dex with halfling.
I like having some more run speed so I still like 13 rogue base, also more sa with 150% ranged power bonus and imp sa feat, imp uncanny dodge, two rogue feats, able to fit 20% doubleshot from killer; at the cost of a bit less base dmg and no tenser spell cast.

I tested swashbuckler and dashing scoundrel seems to stack with rapid fire, so this build should be fine, still Idk if its worth losing the monk extra shuriken chance for the swash stance and doubleshot but seems to be a viable option for trying something diferent, also with swashbuckler you can use other thrown weapons different than shuriken, more at heroic lvls where your dexterity is not very high and you can get some cool thrown weapons with higher base and crit dmg.

I am thinking of a 12/5/3 Arti/Rog/Bard Halfling (...)

He said he wants Shadar-Kai past lifes so being Shadar-Kai is a must have. It's not too hard to find builds if you can have a wide range of race choices.

Also going INT based without Shuriken Expertise and Ninja II and thus also without 10k stars will cripple your number of attacks badly. Because of that not only your proc damage will be much lower but also every point of damage is worth less DPS. A paladin base can also get the same crit bonus as a swashbuckler and the little bit more Doubleshot chance cannot make up for loosing that many extra attacks. Most people forget that even with 10k up all the time you still make use of at least 25% of your Doubleshot value on top of that and with a build without 10k you have it all the time. Also you cannot get your INT as high as you can get DEX because you still need DEX for ranged feat requirements.
