Overview
The Alpha Rex is a massive carnivorous variant of the Rex, infused with lightning energy and significantly more powerful than its base form. It excels in combat due to its heightened damage output and resilience, making it a fearsome dueling and raiding mount. Players typically tame it for high-level PVP engagements or to dominate boss fights where raw power is essential.

Combat notes
The Alpha Rex takes +400% more damage from spike walls, making it highly vulnerable to defensive traps. It is also weak to explosions and melee attacks from metal weapons, increasing its susceptibility in structured combat zones. It is completely immune to damage from mining drills. Focus on exploiting its spike wall weakness for efficient takedowns.
The Alpha Rex has a head hitbox that takes 1.5× damage, making headshots more effective during combat. Focus fire on the head to maximize damage output and reduce engagement time.
