[Trigger] Show invisible units using trigger

[D3athM3at]

Hello everyone,

I have this problem i made this abillity which detects all enemy units with less than 30% health around unit and gives vision of those enemy units to player but i have a problem when i use:

• Unit - Grant shared vision of (enemy unit) to (Owner of Unit)

this wont show units that are invisible i can only see them on minimap, i thought using faerie fire to be cast on that unit but if there is more than 1 it could mess up.. anyone got any idea how to fix this ?

EDIT: found solution with faerie fire if anyone is intrested heres code

Code:

Find the Pray - dummy abillity does nothing just tooltip.
Spell Book Find - disabled spellbook contains "Find the Pray (Movement bonus)".
Find the Pray (Movement bonus) - endurance aura just with movement speed bonus (5 levels (1 level does nothing, 2-5 level gives movement speed).
Detect Invisible(Find the Pray) - faerie fire.
Find the Pray (target) - farie fire buff.

(Entire map) <<< this part
