Ive been curious about this myself. What about electrocute/other runes? red buff i would assume would be less dmg, but ignite counds as a spell to trigger electrocute, but doesn't count as a spell to get increased dmg...which is why im curious one can affect one without another doing the same. So basically is there +20% on electrocute and are you 100% sure ignite do no extra dmg? For example auto attacks should do +20% more damage as well..heres an actual copy paste when it was changed.
[New Effect] When Charm deals damage to an champion, Ahri's abilities deal 20% more damage to them for 5 seconds ...i assume this means qw and r, but am also curious if electrocute/comet/aery/scorch/cheap shot could be modified.c Thanks for testing that im glad to know i shouldn't always ignite the person i charmed for 5 seconds of extra dmg.
