Ring of Energy (Magic Ring)

This magical ring always has a gem of some sort in its setting. Upon command, a pencil-thin beam of energy can be made to shoot out from the gem toward a desired target. The beam automatically hits any selected target located along an unobstructed line of sight, within 60' of the ring wearer. A save vs. spell is allowed to avoid the beam and its damage, and if the intended target makes its saving throw, the beam continues along its straight-line path and may hit an unintended target that lies within range. The power beam of the ring of energy loses potency as it travels outward. 
Target Distance	Damage
1' to 20' 	4d6
21' to 30' 	3d6
31' to 40' 	2d6
41' to 60' 	1d6
The beam only affects living things: golems, undead, and creatures of similar sort are not injured by it, but it does hit such creatures and in so doing expends its energy. The ring of energy cannot be used more than four times in one day. The energy of the power beam is drawn from the Ethereal Plane and each usage has a 3% chance (non-cumulative) of opening a passageway to that plane and causing a terithran to arrive on the Prime Material Plane. Any such creature “summoned” in this fashion appears 30' away from the ring wearer, intent upon destroying the ring (and its possessor, if necessary).
