Magician %/s (KMS FLY 2 & GMS Dawnveil)

Slime Virus is definitely beneficial, as it lasts 60 seconds on a single target.

For Elemental Amplification to affect DoTs, it would have to be a +matk% bonus. It is listed as a +damR% (Total Damage) though in RED. Previously, it was +x%, which could have been matk, or final damage.

That being said, Infinity is listed as a +damage% bonus, which given the example of Berserk/Reincarnation, is a final damage multiplier. If anyone can investigate their damage without Infinity vs with Infinity, we can determine if it's +total damage% or +final damage% and there would be a significant difference in %/s, as I currently have it listed as a +total damage%.

Slime Virus's ability to last 60 seconds on a single target is news to me. The description says that the slime spreads DoT for 10 seconds, splits and then attaches to another enemy only if the first enemy dies. That would mean it only lasts for 10 seconds out of every minute, not 60. Of course the description could be wrong though.

I'm not so keen on how Infinity was changed to work so I hope someone else can help you. Good luck!
