Do debuffs stack?

[烈火]

Can't seem to find any explanation in-game on whether debuffs( and buffs) stacks.
Judging from the icons, it seems that debuffs don't stack and a new only will only be applied after the old one is gone.
But if this is the case, then items that reduces your skill damage to 10 and applies a debuff on enemy feels very weak, especially on multi-hit skills.
Can anyone provide a definitive answer for me?

Debuffs do not refresh themselves. Buffs and debuffs that are a different color will stack.

I'm wondering the same. dots seem pointless unless you get a rare synergy (you won't)

The answer above is correct.
Examples: The item that applies burn to your special won't apply a second burn until the first wears off. If two players have a poison item, they can both be applied at once. You can have two different sources of the Smite buff at the same time.
Player buffs from skills can refresh themselves, like Warcry.

A lot of them do stack. There is something like 20 different versions of the poison debuff that all stack. You can take every poison item no problem so don't feel bad there.

Debuffs that only do damage at the point of wearing off do not stack and do not refresh (Burn and Snare). I also haven't seen alternate versions of them even from different sources. If you are playing Dancer and get the special applies burn gem do not take the special applies burn item. You'll gain nothing.

Edit: Hmmm, seems I might be wrong on this. Maybe it was changed after I last tested it. I definitely remember being disappointed after trying to stack burn on special from different sources.

Same debuffs from the same source do not stack. The sniper rabbit getting burn on their primary from gems will not reset the burn from their primary until the current on is up. However Debuffs of different types stack even if they are applied at the same time. Getting the item that gives a burn debuff on primary and the gem that gives a burn on primary will put two separate burn debuffs on the enemy.

The person above is wrong on stacking. As long as its not the exact same source every debuff stacks.

Just to clarify what others say, different sources of debuffs stack.

Item that burns on special use + skill upgrade that burns on special use = 2 burn stacks.
Skill upgrade that burns on special use ONLY and you use it twice in a row = 1 burn stack, not even refreshed.
burn on primary + primary hits 3 times = 1 burn stack.

Honestly I feel like debuffs like curse (maybe that's the only one) should be refreshed per hit (i.e. shouldn't have to wait for it to time out). Yeah it's a buff, but I feel like it should be a thing.
