|Deal 5 damage to self and allies in the row
Bombom is a Companion that the player can bring along on a run.
Bombom is a high-damage Companion to a reckless degree, dealing fantastic Barrage damage at a good speed but hurting their own row as well as the enemies'. Relying on Bombom for damage necessitates game awareness and a smaller field presence, as ideally Bombom's row is completely empty to avoid hurting allies or Clunkers. Since Bombom will inevitably wear themself out after enough attacks, it's crucial to pair them with healing or Shell. Recalling them only recovers 5 health, enough for a single extra attack, and they still must be redrawn and redeployed, so healing and Shell are far preferable.
Bombom pairs extremely well with on-kill effects like Shelly, the Pinch Charm, the Cloudberry Charm, and the Shield Charm. They can also work to sacrifice cards similarly to Monch, although their self-inflicted damage still limits the effectiveness of this strategy (and they do not gain the killed allies' stats like Monch does). They also do not instantly kill the row like Monch does and instead inflict a fixed amount of damage, so allies with enough health like Fallow, Chikasan, and Chikashi will survive.
