Damage 1d10 bludgeoning

A ring of magical crystals encircles the base of this +1 striking greatclub, allowing it to absorb and store magical energy. These crystals irregularly flash a deep crimson light.


Activate—Absorb Arcana (concentrate)
Trigger You Cast a Spell from a spell slot, and the spell has the acid, cold, electricity, fire, or sonic trait
Requirements The club has no charges
Effect You mentally align the club's crystals to reverberate with energy from the triggering spell. The club gains a number of charges equal to the rank of the spell slot, and the charges are attuned to the damage type matching the spell's trait. If the spell has more than one eligible trait, choose one when the charges are stored.

Activate—Explosive Cone (concentrate, magical, manipulate)
Requirements The club has at least 1 charge
Effect You flip the club around to blast a cone of energy from its base. Each creature in a 15-foot cone takes 1d6 damage per charge stored in the club, with a DC 20 basic Reflex save. The damage type is the same type the charges were attuned to. The club loses all its charges.
