Poison’s effect is double damage, you’d need to hit someone with Ash 8 times within 20 seconds in order to surpass Poison in the long run, which doesn’t sound like much but with the amount of time PvP takes that’s a lot. If you could hit and 800 HP target 8 times within 20 seconds dealing 130 per hit the fight would be over in those 20 seconds and yes regen was factored into that. So in the long run Poison would still actually be winning. And as said in this conversation the tick damage won’t be a primary factor, though I do think it will make SOME impact as I will explain later.
Ice rn is meta with the +40% bleed so I mean it wouldn’t be so bad to give Ash at least a slight buff.
To at least be fair however, hitting one tick with Ash would be enough to put it ahead of Snow in the long run if both have low power, but with high power this would become more negligible. We’d have to see how strong Ash later on I guess.
