Short answer: Yes.<br/><br/>A few things that you can currently gain are, SLAs, Fly Speed, Size Change, Taur-body, Natural Armor (Fur/Scales), Increased Physical/Mental stats (and the odd reduction. They stack with your race, but not others of the same kind), Poison (Stinger/Teeth), most forms of Natural Attack. Then there's cosmetic changes, adding or removing body parts, enlarging/reducing, etc.<br/><br/>An example Item:<br/>Twitiching Tentacle offers the following:<br/>1: New Tentacle (1d4+Str for medium, Bludgeoning, Secondary)<br/>2: Existing tentacle gains penile characteristics/New Tentacle<br/>3: Existing tentacle gains vaginal characteristics/New Tentacle<br/>4: Aspect: +2 Con. Tentacle creatures are enduring and built to last longer than their prey.<br/>5: Essence: -2 Int, +2 Wis: Predatory by nature, but their mind is unfocused beyond its basic needs.<br/>6: Nothing<br/><br/>Current items offer only a limited set, and will get more powerful down the road in terms of mechanical benefits and offering more unique changes. So you'll get to see Succubus Milk+ before long.
