Fargo's Mod/Big Brain Buster

The Big Brain Buster is a post-Moon Lord summoner weapon. On use, it summons a corruption-colored Big Brain, alongside its illusions, that circles the player and deals damage to enemies. If an enemy is nearby, it'll summon more illusions near the enemy that instantly dash and disappear. Unlike most other summon weapons, using it again won't summon another Big Brain. Instead, it empowers the current Big Brain by increasing its damage and size, consuming a minion slot each time used. This effect caps when the Big Brain uses 6 minion slots.
