Forte

Enrobed in bright silks, the forte strikes a shape similar to a dervish dancer, save the spaces between the fabric containing little more than a deep-violet murk. It wears a lacquered mask bearing a bemused expression which is framed by an arrangement of ever-swirling scarves that give an impression of a head. The elemental's hands further betray its alien nature, as they are fingerless balls forever vibrating with barely controlled sound.

Riot Rondo. Phantasmagoria draws these elementals from cries of incoherent rage and mob justice. The resulting forte is a loud creature, both in volume and self-expression. But this is not a harmless artistic spirit. Instead, it strives to create dancing tunes using the pained shouts of others as it beats them to death. The arch elemental values fortes not only for their malicious ability, but also their loud natures can break magical silences which can be deadly to its kin.

Keeping the Beat.

If a creature struck by the forte's sonic shockwave falls prone, the elemental may use its bonus action to immediately make another sonic shockwave attack on that creature. This sonic shockwave does not count toward Sonic Boom.

Sonic Boom.
