How do you turn a trigger of after 120 seconds, and do +20 seconds for every level of a ability?
Example:
Level 1 the ability lasts 140 seconds
Level 2 the ability lasts 160 seconds
Etc..

Thats what i want.

most simple not MUI is
wait (120+(level of ability for casting unit)x20)
turn off (this trigger)
