It adds psionic rules to OSE? Or you have to bring your own psionic ruleset? Love the art BTW.
Hi cl4yt0n thanks for the interest and glad you like the art
Players must enter 'psionic duels' with some of the creatures in the dungeon - in order to disable and capture them. There is a page of rules on how this functions towards the back of the zine. It's a simple system, so it should not add any confusing or convoluted mechanics.
