- No "same" (de)buffs stack
- Tactics stack with buffs
- Morals stack with everything else
TL;DR: Is there any list or any other general rule I'm missing?
So far I've found the following:
Violating Rule 1:
Generally weak buffs that would not be used otherwise.
- Swordmasters blade resistance debuff stacks with other debuffs. It would be kinda useless otherwise, but its still strange.
- Magus Daemonic Armor/ Engineers Flack Jacket (self buffs) stack with other buffs/ potions.
Some tactics just stack, as you would expect. Any passive stat/ armor/ resistance tactics for example.
But it gets tricky when it comes to abilities. Nearly all tactics that change abilities, change the buff or add a buff. For example Knights Encuraged Aim changes the aura. And Dirty Tricks adds a new buff. Since these are now buffs and fall into Rule 1, they don't seem to stack with other buffs. And there a no reported exceptions so far.
I have not found any moral abilities that seemed strange, but absorb. But absorb is generally strange.
