Spellslinger Epic Feat

You can sling cantrips with exceptional speed, greatly decreasing their casting time. You gain the following benefits:

Cantrips you know with a casting time of 1 action may be cast as a bonus action instead.

If you cast two cantrips on the same turn that target only the same creature, you may use your reaction to cast a third cantrip with a casting time of 1 action or bonus action that must target only that creature.

Two additional damage die by EPIC level 27 from EPIC levels for cantrips with damage die.  If number of beams, etc increases instead, then two additional beams.

You learn three cantrips of your choice from any class spell list, which are class spells for you. If your class does not have a spellcasting ability, you choose which ability (Intelligence, Wisdom, or Charisma) is your spellcasting ability.
