Amulet of the Elder

While attuned to this holy symbol, some of your healing spells are now able to deal damage to enemies and vice versa as long as the damage type is radiant. 

For example: casting a Guiding Bolt at an ally can now heal them for the amount of damage it would have dealt. Instead of having advantage on attacks against them, they gain advantage on their next attack.

Word of Radiance, a cantrip, can now be used to heal allies or creatures of your choice within the spell's radius.

Casting Cure Wounds can be similar to Inflict Wounds now except the damage is radiant.
