Despite its slender appearance, the {rocky_devil} should not be underestimated; it will attempt to maul any creature it encounters, regardless of size, as if entirely lacking a survival instinct.

This fearlessness might stem from its remarkable ability to heal and regenerate its shell, allowing it to go all out when hunting.

It is also able to slightly alter the shape of its shell, but I have yet to determine to what extent and for what reasons.

• Rocky Devil shines against high-danger encounters; talent synergy strongly shapes its tier.
• Prioritize raw damage in early acts, swap toward survivability in mid–late game.
• Compare with similar-role creatures (taming difficulty, food preference) before locking it into your deck.
