Echoes of Thunder
Benefit: When you hit with any thunder attack
power, you gain a +1 bonus to damage rolls until the
end of your next turn. The bonus increases to +2 at
11th level and +3 at 21st level.
Let's say you have an AoE thunder spell that targets 10 foes. Next turn they are all still alive and didn't move and you can do the same attack again.
Let's further assume you hit on all guys for simplicity sake.
You hit on the first guy thus triggering echoes. You roll damage getting a +1 bonus to the damage roll.
You roll and hit the next foe. You roll damage getting a +2 bonus to the damage roll.
You roll and hit the next foe. You roll damage getting a +3 bonus to the damage roll.
....
You roll and hit the next foe. You roll damage getting a +10 bonus to the damage roll.
Next turn
You hit on the first guy thus triggering echoes. You roll damage getting a +11 bonus to the damage roll.
You roll and hit the next foe. You roll damage getting a +12 bonus to the damage roll.
You roll and hit the next foe. You roll damage getting a +13 bonus to the damage roll.
....
You roll and hit the next foe. You roll damage getting a +20 bonus to the damage roll.
The total damage this feat contributed was 1+2+3...+20 = sum(i,i,1,20) = 210
algebraically sum(i,i,1,2n) = n(2n+1) = 2n^2+n
If we plot the growth with the number of hits we find that the damage contribution is quadratic (I know quadratic is less than exponential but I had to get some attention somehow).
I know that a variant ruling on AoE powers says to make 1 roll and apply it to all the monsters, but if the DM goes with the 1 roll / monster how would this abuse be met? Are there some rules that prevent such abuse? Is there any way to get this kind of growth with attack bonuses(untyped until end of your next turn)?
