Dual Hex
When you cast a Hex as a Magic action, you can cast a second Hex or cast the original Hex a second time targeting a different creature as a part of the same action. Both Hexes must have a casting time of an action. When you Cackle, you extend the duration of both Hexes by 1 round.
Each target affected by your Hexes counts as being the sole target of your Hex for Insidious Spell and other Witch features.
