[Trigger] Kill Rush Spell request

[Weigazod]

I need help with this spell. I have never tried anything like this before.

Intended unit​

Beastmaster's bear

Targeting​

It's a point and click spell. If the cursor targets a unit, the bear when out of range will track the location of the targeted unit and approach it before executing the spell.
If the cursor targets an empty space, the bear will execute the spell with the targeted point as its final destination.

Description​

The bear rushes forward, passing through ground units and buildings while performing the mauling animation. It can not pass through obstructed terrain or doodads or Ground- pathing block.
Ground enemies it passed though will be dealt damage.
When reaching the final destination, the bear does an area stun and dealing additional damage to ground enemies.

Level​

Have 3 levels correspond to 3 levels of bear
Lv1 - 30 rushing damage, 1.5s stun, 25 stun damage, 250 stun area
Lv2 - 60 rushing damage, 2s stun, 50 stun damage, 300 stun area
