So I created a script to present Bersy's idea that unicorns can now cast "Blinding Light". The spell is cast by clicking on the Unicorn stack on its turn, blinding all the adjacent enemies for 1 turn.
In short, a pure erm implementation of a custom creature spell. Apparenlty, while my cursor is over the unicorn and I hit "W", I still want unicorns to wait instead of casting.
