[Snake]

Dagger skill should warp you behind the enemy, and a Youkai appears where you have left. Some sort of substitution jutsu.

At the ranged skills.
Summon at the targeted location, but:
--If the user targets and hits an enemy, the Youkai latches to the enemy, casting Grapple skill (using the same LV vs LV grapple success formula).

EDIT: Typo.
