Backup Sword. If Valor is disarmed during combat, it can draw a second electric sword. Electric Shield. When hit with a melee attack, Valor's electric shield deals 7 (2d6) 2d6 lightning damage to the attacking creature. False Appearance. While Valor remains motioneless, it is indistinguishable from an inanimate statue. Lunging Attack. When Valor makes a melee weapon attack on its turn, it can attempt a DC 12 Dexterity (Acrobatics) check to increase the attack's reach by 5 feet. Sentinel. When Valor hits a creature with an opportunity attack, the creature's speed becomes 0 for the rest of the turn. Creatures provoke opportunity attacks from Valor even if they take the Disengage action before leaving its reach. When a creature within 5 feet of Valor makes an attack against a target other than Valor (and that target doesn't have this feat), Valor can use its reaction to make a melee weapon attack against the attacking creature.
Electric Sword. Melee Weapon Attack: +8 1d20+8 to hit, reach 5ft, one target. Hit: 9 (1d8 + 5) slashing damage plus 14 (3d8) lightning damage.
Temfala Tower. The miniboss arena for Valor and Ambiguity features strong wind coming from the opening to the east, giving any creature within the arena disadvantage on ranged weapon attack rolls and Perception checks relying on hearing. Each round, 3 (1d4+1) 1d4+1 mechanical angels will ride the wind into the arena, targeting creatures not protected behind a pillar or wall with the shove action before leaving the arena that same turn.
