dummy casting an ability

[GIMLI_2]

hi
i made an ability with a casting time of 2 seconds.
after this 2 seconds, the skill deals damage based on intelligence and gives the target a buff where it gets slowed.
well the damage source is done with trigger

• Unit - Cause FrostBlast_Caster to damage FrostBlast_Target[FrostBlast_Integer], dealing ((Real((Intelligenz of FrostBlast_Caster (include bonuses)))) x 2.00) damage of attack type Spell and damage type Normal

for the slow: i created a dummy unit at the same time i damage the unit and let it cast "slow" on the target.

my problem is that the slow takes more time to cast then the damage.
that means after the 2 seconds, the target takes damage and 0.3 seconds later the dummy casts his skill.

is there any opportunity to make the dummy cast faster??

Change these fields to 0 for dummy in object editor for instant cast:
Art - Animation - Cast Backswing
Art - Animation - Cast Point

Why not base your ability in frost nova which slows by itself, and create a dummy unit?
Or base your ability in Slow?
Dont use dummies if you dont have to..
