At will: dancing lights, light, minor illusion
3/day each: charm person, invisibility, mirror image, silent image, sleep
Shapechanger. The aranea can use its action to polymorph into a Medium spider-humanoid or into a humanoid, or back into its true form, which is that of a monstrous spider. Its statistics, other than its AC, are the same in each form. Any equipment it is wearing or carrying isn’t transformed. It reverts to its true form if it dies.
Spider Climb. The aranea can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
Web Walker. The aranea ignores movement restrictions caused by webbing.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 21 (4d8 + 3) piercing damage. Additionally, if the target is wearing nonmagical armor or wielding a nonmagical shield, either the armor or shield (GM’s choice) takes a permanent and cumulative -1 penalty to the AC it offers. If the penalty reduces the armor to AC 10 or if the penalty reduces the shield’s bonus to +0, the armor or shield in question is destroyed.


When flanked or retreating, the leucrotta instinctively kicks with its rear hooves.
