I'm creating a new class for Goromor, which also involves a new magic system. Basically tis a mage, who, by scarring himself in different ways, can get various different powers. There will be four levels of powers he can gain, and he'll have about 7 of them active at a time by 20th level. I was thinking for the 1-5 powers you could have boosts to movement speed, the ability to rage or whatever... and then for 6-10 powers stuff like a couple of basic spells, more movement speed... for 11-15 permahaste, large skill bonuses, low dr and fast healing... and for 16-20 ability boosts, skill increases, DR, fast healing... etc.
But really, I need suggestions. :)
Powers that duplicate low-level spells but are continuous can be nice bonuses:
Endure elements
Feather Fall (at will)
See Invisibility
Water Breathing
Water Walk
Comprehend Languages
Detect Magic
Tongues
Spider Climb
Also, other standard abilities include (most of which you list)
DR
Fast Healing
SR
Regeneration
Fast Movement
New movement modes (Swim, Fly, Burrow, Climb)
Energy Resistance
Evasion
Uncanny Dodge
Mettle
Mind Blank
Non-detection
Darkvision
Low-light vision
Immunities (disease, posion, sleep, paralysis, petrication, fear, etc.)
Divine/Unearthly Grace
That's all I can think of off the top of my head, but I'll post if I come up with more.
