Altraloth (Piscoloth Version)

Siege Monster. The Altraloth deals double damage to objects and structures. 

Innate Spellcasting. The Altraloth's spell casting ability is Charisma (spell save DC 19). It can innately cast the following spells, requiring no material components: At will: Detect Evil And Good, Telepathy 3/day each: Freezing Sphere, Watery Sphere 1/day each: Far Step, Tsunami

Reflective Carapace: Any time the Altraloth is targeted by a Magic Missile spell, a line spell, or a spell that requires a ranged Attack roll, roll a d6. On a 1 to 4, the Altraloth suffers the normal effects of the spell. On a 5 the Altraloth is unaffected. On a 6 the Altralothand is unaffected and the effect is reflected back at the caster as though it originated from the Altraloth, turning the caster into the target.
