Telepath Tactics now supports two more VFX spawn locations: OnCenter, which is basically for large area-of-effect animations (e.g. Dark Vortex, Pyro Hail, etc.); and TowardCenter, which is for projectiles that will end in an OnCenter effect (e.g. Light Bomb).
While OnTargets will spawn a copy of the visual effect on every character targeted by a skill, and OnSelf will spawn a single copy of the effect over the character using the skill, OnCenter will spawn a single copy of the effect centered over the attack tile the player clicked when launching the attack.
TowardCenter, in turn, spawns the effect at the OnSelf location and moves it to the OnCenter location over time.
