Trilling Crysmal

Six long, needle-like legs splay from a crystal cluster crowned by a silvery crystal almost 4 feet tall. It looks nothing like its cousin the ordinary crysmal.

Only +2 or better weapons harm it, and weaker ones risk a 10% chance of shattering on impact. Its razor legs slash for 1d8 each, two per opponent, so it can fight three foes when surrounded.

Six times a day it shoots a ridged, diamond-hard barb (light crossbow range) that pierces heavy armor for 1d4+1. The barb then bursts into 3d4 splinters, temporarily costing the victim 2 Strength and 4 Dexterity, and running, fighting or other strenuous activity deals 1d6 each round while they remain. Digging them out costs 1 hit point per splinter, but any cure wounds spell removes all of them from one victim.

Spells aimed directly at it by casters or devices have a 75% chance to be reflected through its central prism. The spell leaves a random facet (1d6 for one of six directions) and takes effect (1d4 x 10) + 20 feet off, hitting anything there. Area spells like cloudkill only reflect when centered on the crysmal.

Uncommon on the elemental plane of Earth, trilling crysmals abound in the quasi-plane of Mineral, hunting in large numbers along its edge with the Positive Material plane.
