Hello everyone, after almost 300 hours of table play, my party is going against the terrible korriban sith temples to find a sith holocron. The group member literally lost limbs in this adventure: 2 fingers, 2 arms, one eye, a critical NPC.

Now they just faced almost all theirs fears and are about to enter the final room in a sith temple where a sith holocron is. They worked so hard they have to get it. But how would I leave them use it. Sure it gives the holder of the sith holocron the sith lore on there knowledges. But what more should it give them?

Special note : one of the player have an obsession over sith culture and dark force users. He is the most likely to take control of it.

Thank you guys !

Disciples of Harmony has a bit about what a Sith mentor would mean to a PC: the cost to learn Heal/Harm, Misdirect, and Protect/Unleash are -15xp for the base power, however the PC also doubles the amount that morality drops in any instance it would go down. That should for sure happen with a Sith Holocron.

I would also have it reduce the Strain Threshold for PCs who are in its presence for more than a few moments out of a day, something like -2 ST. Knowledge: Lore would be a career skill for anyone who possessed it, and if a non-dark side force user had control of it, I would have the holocron provide a free dark side force pip on every force power check until the PC turned to the dark side. Similar to the vergence on Dagobah, you might have it require the wielder to add Force Die equal to the Force Rating to any discipline checks, with dark side pips removing successes (and light side doing nothing).

Anything else would boil down to the personality of the Sith who made the holocron, what that individual's story was. If they were a warrior, perhaps grant them lightsaber as a career skill, or allow them to buy a rank of Parry for 10xp. Other Sith might grant them Deception, Coercion, or the like. Perhaps the maker was one to embrace pain, and will only grant benefits to the PC if they are currently suffering from a critical injury.

The critical injury is quite interesting way to use it.
