Increase/Expand Deimos Carnis (Rex) Hitboxes

[Duality52]

For reference:

The Deimos Carnis and their Rex variant suffer from unusual hibox behaviors. Their main bodies are the only permissible areas to damage the Carnis, yet their legs do not have any hitboxes. In other words, attacking their legs inflicts no damage to the Carnis.

Expand the hiboxes to the Carnis's legs, making it easier to damage the Carnis with non-AoE weapons. Considering their behavior, it's really difficult to consistently headshot them. This compensates by increasing their hitbox size, extending it to the legs.
