Bizarre Stand

A spectral figure resembling the deity/extraplanar creature you swore allegiance to appears next to you. The spectre attacks any creature that moves within 30 ft (10 mt) from it. The creature must succed on a DEX saving throw, or receive 20 points of damage (wether it is radiant, bludgeoining etc., it depends on what kind of weapons/magic spells the spectre is likely to use). The spell lasts until dispelled, or until the user receives more than 10 points of damage.
