Do damage over time effects stack?

The ability "Rend" makes your target bleed for 3 second. What happens if you consequently use the spell? Will the damage stack or is it a waste of rage to use the spell consequently?

You will refresh the timer on the rend debuff, not apply a totally separate effect. However, you will still get the initial damage, and if two separate barbs apply a rend, you will have 2 rend debuffs.

  • Is there a way to see this in game? I don't see buffs/debuffs below monster portraits at all.

  • Unfortunately no, or we'd have much more concrete answers to questions beyond observation. I can tell you this, if 1 barb applies rend it ticks quickly, if two barbs apply, it ticks even faster. If a single barb applies it rapidly, it does not tick any faster, but will refresh how long the effect lasts.
