Broodmother Lysrix cannot normally be tamed, with admin ForceTame being the only reported method; even then, it may not be rideable and is mainly a trophy or combat companion. Defeating her advances Tek progression and can provide substantial chitin, especially when using Megatheriums. Prepare well-bred Megatheriums or alternatives such as Rexes and Therizinosaurs, supported by a Yutyrannus and optional Daeodons, then stay mounted to manage buffs, healing, commands, and the surrounding attackers.
