Death fire touch stacking

i believe no

it does a set DOt based on your AD+AP and your spells refresh it. not stack it

however i believe 5 champs with deathfire can put 5 deathfire dots on someone,all doing damage based on their ad+ap

It refreshes the duration when reapplied.

I'm not sure whether or not it stacks if multiple champions apply it though.

if it stacked it would go from useless to broken.

Thanks for clearing that up
