The party regroups and enters the Crystalline monolith..
Main features: Large tower with spiral staircase leading to the top some 200 feet high. In the center of the tower is a crystalline stalagmite/tite with a glowing ball of light similar to the sun in the center, this is the core I suppose. Damage to the core will cause wacky things to happen, such as bursts of light blasts firing at random, as well as causing the light antibodies to target the agressor.
