The Mind Defined!
When you're roaming through a dungeon and you meet something elemental, transcendental, or hell-bental on destruction . . . it's time to get mental!
GURPS Dungeon Fantasy 14: Psi lets you introduce the power of the mind to any Dungeon Fantasy campaign. Written by GURPS mastermind Sean Punch, this supplement offers:
•Two dozen psionic abilities, including Battlesense, Levitation, and Transdimensional Sight.
•The mentalist profession, a 250-point template with customization notes for six different approaches.
•Lenses that add any of the core GURPS Dungeon Fantasy 1: Dungeons possibilities to the mentalist – plus a lens that adds mentalist abilities to any other template!
•Power-ups that augment the masters of mental might, such as Bonded Creature, Elder Lore, and Death Possession.
•A look at psionics in the campaign, including how it interacts with magic, what effect it has in combat, and how it intersects with dungeon-dwelling danger.
•Things that threaten with the power of thought. Beware the psionic encounter table and nine new mentalist-menacing monsters!
•Incredible gear especially suitable for psis, such as telekinetic's webbing, hypno-discs, and the powerful pyramid hat.
