Roll 1d8. Or roll 1d6 and +1 per sacrifice of some sort.
- Insect Vision - Gain the ability to see otherworldly colors and in the darkness, but eyes are gross gigantic bee eyes which freak normal people out and animals hate you.
- Arcane Gift- cast one extra spell per day, but voice alerts the Holy Daemon Hunters who listen for such vile sounds with huge brass ear trumpets. It will take a while for them to find you...
- Dark insight - ask the GM one question per session, but limbs become gnarled (movement/DEX penalty)
- Breath of Satan - exhale a cloud of stinging darkness once per day, but always stink of rotting meat (+1 encounter rolls)
- Demon Strength - minimum 1/2 max damage, but filled with uncontrollable rage (WIS check to overcome)
- Blight - touch causes 1d6 rotting damage ... but it is on ALL THE TIME. clothes and wood rots too but not as fast
- Dark Assistance - summon a dark familiar that gives permanent +1 to something, -1 to 2 other things, such as +1 to attack, but -1 to INT and WIS checks
- Blood Storm - spend 1d4 hit points to cause blood to erupt from the ground causing all enemies HPd4 damage (rolled a 3, then lose 3 HP but all opponents take 3d4 HP damage), blood damage cannot be healed by clerics or normal rest - only through vile ritual.
Roll 1d6 and wear your crown like you own it - because you do. Forever.
- Crown of the Xaos Mage - made of broken bone fragments that is surrounded by a nimbus of flame. Wearing it grants double effect from spells, but control over those spells (targeting, duration, etc.) is weakened.
- Crown of Aszor Mhauve - A metal circlet with thin delicate antenna adorning it. Wearing it allows the bearer to command war.bots, but at the cost of her humanity. Each command drains some part of their person, eventually they become a flesh robot and the crown only works on humans.
- Sludge Crown - A classic crown of gold that slowly melts the person's flesh. They are still fully functional, but have no form, which allows them to be able to slip through cracks under doors and whatnot. The bearer can also communicate with and command slimes and oozes. The crown "melts" with the person but reappears solid if they die.
- Undead Lord - a crown made of skeletal hands of babies and children. Wearing it makes you evil (even looking at it makes you suspect). It also allows you to command undead equal to or below your level. More powerful undead will either work for your favor or try to kill you and take thr crown or both. Vampire politics ... worst hell ever.
- Ice Baby Crown - a tiny crown that gives you ice wizard powers and reverses your aging at double rate. eventually you'll turn back into a baby. Imagine a toddler wizard having a full-tilt temper tantrum. Glaciation and another ice age are coming ...
- Crown of the Stone King - wearing it turns you to stone - mobile intelligent stone! Your flesh is stone, so things that don't damage stone can't damage you. This also means that spells designed to heal flesh don't heal you - nor does rest; damage to you is permanent. You become incredibly strong to the point that delicate tasks take great concentration (WIS and DEX checks).
