Occult Skill Unlocks are... interesting.
Basically, having access to Psychic Spells or the
Psychic Sensitivity feat gives you access to a bunch of Divination effects (plus a little mind control) with skill checks.
There are some feats that interact with the system, but none of them are all that good.
You know what
are good (or at least
hilarious)?
Chakras!
Here's how you use 'em:
1. Have a ki pool.
2. Have Psychic Sensitivity OR levels in one of the Occult Classes.
3. Spend one ki per round as a swift action to progressively unlock more potent abilities (to a maximum Tier of HD/2) or maintain your powers.
4. Make a Will and Fort save each round; the DCs are 10 + the sum of the tiers of awakened Chakras. You do get your Charisma as an untyped bonus to these saves, though.
4a. Failing the Will save dazes you for a round and closes all your Chakras.
4b. Failing the Fort save causes you to take [number of awakened Chakras]d6 damage.
5. Pick
one ability from the tiers you've unlocked so far each round.
What do you get for each of these?
Tier 1: DR [Awakened Chakras]/- for one round.
Tier 2: Fly (Average) at your base land speed.
Tier 3: Gain a Breath Attack that deals [Awakened Chakras - 1]d8 damage in a 30-ft cone.
Tier 4: Heal yourself or someone you touch for 1d8 + [2 * Awakened Chakras] damage and remove one of the following: confused, nauseated, sickened, staggered, or stunned.
Tier 5: One creature within 30ft must make a DC 10 + 1/2 HD + Cha Will save or be staggered for a round.
Tier 6: Freaky psychic eye opens, giving you True Seeing for that round.
Tier 7: You can use any two of the above at once, or just one and roll twice for all d20 rolls and take the better result.
There are 4 feats you can take that'll help with the above:
Chakra Mandala: Halve the damage from failing a Fort save;
Prereqs: Ki Pool.
Chakra Initiate: You get a special pool of 3 Ki, which you may only use to open or maintain Chakras.
Prereqs: Level 2+
Chakra Adept: You get +1 Ki to your special pool. When you maintain Chakras, you only have to attempt either the Will save or the Fort save. Plus, you can use your Chakras for a round after you stop spending Ki points.
Prereqs: Level 8+
Chakra Master You get +1 Ki to your special pool; plus, you can spend +2 Ki points when opening/maintaining your Chakras to get the benefits of an extra Chakra that turn (so two normally, three once you've hit Tier 7).
Prereqs: Level 14+
There's also the
Serpent-Fire Adept, a Monk archetype that boosts your Chakra use. It's not that bad, actually.
I might end up doing a mini-handbook for this thing.
