Slitherine

Suggestion - eliminate the mana requirements to use this ability. This should be an innate ability (after the exorbitant costs of the upgrade).

No issue with the spell that grants the ability to other units as that is a spell which grants the ability to a unit that normally doesn't have it...

In that case I would reduce the range & add a cooldown. Make it useable every 3 turns & a leap range of 2-3 tiles.

It would still be pretty good to attack support units, flank enemies & simply move fast.
