Don't double post...
Which skill? The first three skills are all edited normal abilities only... The only triggered spell is the ultimate, Mana Void... and oh, blink uses a trigger for the fading AM...
1st skill - Just an ability based on Feedback (Human)
2nd skill - Just an ability based on Blink (NE) + a trigger for the fading AM
3rd skill - An ability based from the magic damage reduction abilities (there are different spells you can use as base, I'm not sure which ones show icons)
Ultimate - dummy ability based on channel. then a trigger which fires when the ability is casted, checking the difference between the target's max mana and current mana, multiply it via the multiplier and set it as the damage, then pick every enemy in the AoE around the target and deal the damage.
And what do you mean by constant or interface like dota?
