Thorn Crystal
Thorn Crystal
Thorn Crystals are glowing red, blue, or green crystal formations sometimes found in Oranbega tileset mission maps and in such places as the Eastgate Park neighborhood of the Hollows.
On outdoor maps, these Crystals are not persistent and will fade some time after the critters around them are disturbed.
Crystal of Pain
Crystals of Pain are red and are injurious to the Hit Points of player characters, buffable pets (including Mastermind Henchmen), and NPC mission allies. Naturally, they are not injurious to the Hit Points of foes and are thus useless in aiding their defeat.
Crystal of Vitality
Crystals of Vitality are blue and increase your Recovery rate. Foes are not immune to the effects of Crystals of Vitality and will also benefit from an increased Recovery rate.
Crystal of Health
Crystals of Health are green and increase your Regeneration rate. Foes are not immune to the effects of Crystals of Health and will also benefit from an increased Regeneration rate.
