Grenade burn damage

Can someone tell me what the burn damage on a grenade is? I am about to train Isak on lvl25, 50% extra burn damage, trying to find out how much the burn damage equates to. Any help or suggestions are appreciated! Thank you!

 

It should be 10% of the hit you make.
If you hit somebody with 1000 damage, the burning effect would do 100 damage for 4 seconds (not 5 as written in grenade UI).

There are two Isak's talents, both add +50% damage for burning effect, so with those talents, when you hit with 1000 damage, crit would do 200x4.

 

I think the debuff lasts 5 seconds, but the first second doesn't deal damage, so just 4 burn ticks over 5 seconds. I imagine it's like this (if I'm right) because you're already taking significant damage from the grenade itself during the first second.

 

Thank you for taking the time to answer! I've searched everywhere for that and couldn't find it. Maybe I wasnt searching for the correct term. I knew I loved the grenade for a reason!
Thanks, Irie!
