Hello,
In the video found below you'll see what happened, I'll recap it here.
Fizz has 56 Armor, 325 HP Zed has 225 AD Zed Ultimate is supposed to deal 225 Damage + 35% of all the damage dealt during the mark, after 3 seconds. During the mark Zed dealt only 250 damage. So after 3 seconds, Fizz should take 225 + 35% of 250 Damage, and die. Fizz takes 30 damage from the mark.

Mullster1 votesUntargetability stops the ult from activating on them. The proc of damage you see afterwards isn't your ult, it's scorch. I checked your runes in your game to make sure and it was definitely scorch and not your ult. So it's not a bug.
Jayavarmen1 votesOhhhh, that's interesting. I just realized the mark only applied after reappearing, not when you first use the R.
To be honest, that's not a very intuitive mechanism. When you use the R on Fizz, he's targetable. It's easy to understand that you can't target him with anything during Playful, but if Fizz is already under the effect of a targeted spell, I would expect the spell to proc.
Today I learned!
