From a defensive / tanking perspective this tree is massively more powerful than anything else that exists. It's like it takes most of the best tanking things from Stalwart Defender/Sacred Defender, Radiant Servant, Enlightened Spirit, and Nature's Warrior and rolls them all up into one tree. And it all seems to stack with what is already out there. And the only "drawback" to getting it all is you "have" to be a construct. 15 Arti/ 4Pal / 1 Sorc/Wiz will likely be outclassing any other possible tank build
Consider from this tree alone with 15 Arti you get:
+105 Maximum Hit Points (4 cores + 50 core 4 + 15 Tier 1)
+50 Positive Spell power (4 cores, 15 Tier 2, 15 Tier 4)
Permanent Shield Spell
Armor Mastery
50% Armor bonus from armor or docents
Massive Temp HP (Renewal Construct)
+2 CON (Tier 3/4)
+6 CON (Embed Component)
No Combat Expertise penalty
No Arcane Spell Failure from armor
+4 to Fortitude Saves
+20% Racial bonus to maximum hit points
immune to most forms of knockdown
Coupled with massive self healing from
Repair SLAs - uncapped
Repair Spells (on separate cooldown?)
Reconstruct SLA on a 6 sec cooldown
Reconstruct Spell (on separate cooldown?)
Cleric type aura for repair
Lots of repair spellpower
Additionally from native spells with no ASF
"Fulltime" Tenser's Transformation (Full BAB = full armor PRR, +4 Strength, Dexterity, Constitution, +6 Armor Class)
Radiant Forcefield
Master's Touch (easy Tower Shield)
And from Arti:
All scrolls for buffs, heals, etc (no ASF)
Traps
Feats
Pick up standard defensive stance from Paladin and AC from Sorc/Wiz, and Ascendant Bond from Aasimar and you have more total defense than any other build could dream of achieving:
+20 CON, 100+ base HP, 70% HP bonus = massive HP pool
Ability yo reach 500+ AC (ref
https://www.ddo.com/forums/showthrea...enloft-Edition and swap AC from fighter for AC from new tree)
Better self healing then a cleric with all the SLAs and Spells on short cooldowns + aura + temp HP
If this tree had a displacement SLA and a little more PRR it would be everything a tank could dream of having - all wrapped up in one tree.
Unlike most trees - there also seems to be very little "filler" or AP spent on things you don't really need in order to get to the next level. In other words - every AP you spend is something you want. Compare that with say Radiant Servant where it is often required to take several expensive, little used enhancements to get to the Tier 5 aura.
I think the best of multiple trees + several other difficult/impossible to get enhancements is a bit too much for one tree. Especially considering that everything in this tree seems to stack with other defensive trees - you can't have two defensive stances from Fighter/Pal but you can have a defensive stance and everything from this tree.
Since it mirrors a defensive stance - consider making it one so it can't be stacked with Fighter/Paladin or add the ability to have both Fighter/Paladin stances active at the same time so there are still some choices to be made. (Thou this tree still brings so much more to the table than Stalwart/Sacred Defender it's hard to see not strongly considering it for a dedicated tank build)
Dropping Reinforced Armor to Tier 3 from Tier 4 will kill most of the Pal/Fighter tank builds and make them Pal/Arti or Fighter/Arti because they can now get everything they got before plus easy/cheap perm shield, more HP, more Positive SP, and a free feat for combat expertise all for less AP.
