[Q] Which buffs / debuffs stack

[chorba69]

As the title says, which buffs / debuffs stack ingame?
Exists there maybe a thread / list already? If so, then my bad because I haven't found any.

Does this armor debuff stack:
Duskbringer's Staff (20% armor decreased) + Grimm's passive ability (20% armor reduced) + Toor arcane ability (15% armor reduced)?
Is the wording here important (decrease and reduce)?

Or this hit chance debuff:
Fireball (25% hit chance reduced) + Grimm's passive ability (35% hit chance reduced) + Toor's arcane ability (15% hit chance reduced)?

And yeah, I know that 75% hit chance reduced is maybe a bit too much, but I'd still like to know which things I can/should combine with.

For your examples stated, I believe the highest debuff is taken into account. Debuffs usually don't stack if it's the same type.
