[Trigger] Drain soul

[jj84]

Hi guys i need a gui spell that when the caster casts it on target unit the caster damages levels of ability ×100 and a soul leaves the targeted body when when it enters to caster body it restores health of caster unit (levels of ability ×100).
Soul system should be like this spell Example system. (Necromastery soul return)
