Combat
Though mariliths thrive on grand strategy and army-level tactics, they love physical combat and never pass up an opportunity to fight. Each of a marilith’s six arms can wield a weapon, and the creature gets an additional three weapon attacks with its primary arm. Mariliths seldom rush headlong into battle, however, preferring to hang back and size up the situation first. They always seek to gain the best possible advantage from the local terrain, obstacles, and any vulnerability or weakness in their opponents.

A marilith’s natural weapons, as well as any weapons it wields, are treated as chaotic-aligned and evil-aligned for the purpose of overcoming damage reduction.
