Electrical Touch. Whenever the zeraora makes a melee attack against a target and the attack hits, it deals an extra 2 (1d4) lightning damage to the target (included in the attack).

Close Combat. The zeraora makes two unarmed strikes, or two claw attacks, and a tail attack.

The zeraora charges super-powered, bright-blue electricity through its fur and claws before slamming its clawed fists onto the ground, creating a powerful electrical shockwave. All creatures within 30 feet of zeraora must make a DC 18 Constitution saving throw, taking 32 (4d8+3) lightning damage and be knocked prone on a failed save, or half as much damage and be pushed back 10 feet from their current position on a success.
