Spirit Infusion

General
Spirit Infusion is one of the Spell cards in Minion Masters.

Timings
The first spirit is released after 2 seconds, and the rest are 2 seconds apart.

Targeting
As soon as a spirit appears it targets a random minion and flies towards it.

The spirit can't target minions inside of Black Hole.

The spirit can target invisible minions.

The spirit can't target a minion that already has Spirit

Effect
The minion gains 200 health after the spirit reaches it.

If the targeted minion dies while the spirit is in flight then the spirit flies to where that minion died but has no effect when it gets there.

If a minion enters Black Hole after being targeted by a spirit, the spirit still flies towards it. If the spirit hits while the unit is inside of Black Hole then it has no effect.
