Treachstone

Treachstone is the final boss of the subchapter Frozen Legion on Tumore mode, debuting in the stage Treacherous. He is the alternate form of Bedridden, now remaining stationary until damaged or when the cannon is used, instead of rushing you down. He trades direct damage and knockback for piercing AoE and Frostburn infliction and a much more aggressive second phase that further trades half of his resistance and beam damage for raw pushing power. Treachstone is a giant Robloxian with black clothing and a cross on his torso. He wears a black hood, black horns, stone pauldrons, stone hands, and some spikes on his shoulders. In the second phase, his right arm turns into an ice crystal and gains icy wings on his back.
