A question about +X and +elemental damage weapons etc
Ok, my understanding so far is.
Bob the fighter has a warhammer, which does d8 damage. On average, he’ll do 4.5 damage with that weapon (excluding all other factors such as strength, specialisation etc)
Bob gets a +1 warhammer, so now does d8+1 damage. On average he’ll now do 5.5 damage, and hit slightly more often due to the +1 to hit – so obviously better.
If Bob gets a flaming warhammer+1 it does the base d8 damage, adds one for the magical plus, then adds another d6 for the flaming. So we’re on 4.5+1+3.5 or 9 damage with a +1 to hit.
At low levels the +to hit can be more helpful than the +damage, as stuff can be quite weak but hard to hit - thinking of the bats in necro doom on korthos for instance.
Hopefully that’s all right.
Now, under the bane description, it says that the weapon functions as if it were a +1 weapon against the target group. It gives the impression that it is in *addition* to any + from the weapon itself .
E.g. if Bob has a +1 human bane warhammer, and swings against an orc, he does d8(base damage)+1(magical bonus) damage.
If he swings against a human, he does d8(base)+1(plus on weapon)+1(bane target group)+d6(actual bane damage)?
Question 1
So, if Bob had a +1 human bane warhammer, and a +1 acid warhammer – would he actually be better switching to the human bane against human targets to get the slight damage and hit bonus from it?
Human bane = d8(base)+1(magic)+1(target group)+d6 (bane)=10 damage, +2 hit
Acid elemental=d8(base)+1(magic)+d6(elemental)=9 damage, +1 to hit
Of course, with the damage from bane/elemental/pure good etc coming from extra dice, it’s just as probable that you will roll a one as a six. Over time, you might average out to 3.5 or whatever… but your damage could spike or trough depending on the random numbers generated.
However, a + weapon does a fixed damage. A +3 warhammer gives +3 to hit, +3 to damage. If you were hitting on everything but a 1, then the +to hit makes no effective difference, and the +3 damage is slightly under the average you can expect from a bane/elemental/alignment type – but it is consistent.
Question 2
So, in theory, once you are able to use +4 weapons at level 6 or so, is it theoretically better to switch away from the +dice weapons to the fixed magic bonus types to give you a smoother and more consistent dps?
Again, I know that I'm exluding things like strength bonus, enhancements, feats etc - but I'm trying to understand the fundamentals here.
Question 3
As you continue to level, then the extra suffix’s start to be available on higher +x weapons again, so I presume that eventually you want to be looking for +5 weapon of elemental/alignment/bane damage… but do people have a rule of thumb for when they look at upgrading?
My guesses at the moment are:
get a +1 (elemental/bane/alignment) and use that until +4 weapons become available
use a +4 or +5 weapon until high enough level that you can switch to:
+3 (elemental/bane/alignment) become available to you, then switch to:
+x (elemental/bane/alignment) as each becomes usable
Thanks in advance for any advice on this.
