Amulet of Energy

This spiraling pendant is made of two magic-sensitive panes of colored crystal, with each piece being attuned to a different arcane element. If you can cast spells, you can use the amulet as a spellcasting focus while you're attuned to it.

The amulet has 4 charges and regains all of its expended charges each day at dawn. Whenever you would deal fire or lightning damage with a spell or effect, you can expend any number of charges to reroll that many of the spell or effect's damage dice.
