I submitted one for the Barbarian. Warp Barbarian. At 3rd lvl, its barely noticable. Minor bonus to hit/ dmg and minor hit to your AC. At 6th lvl things start getting interesting. The barbarians muscles start to writhe like snakes undern his skin. He goes into a rage. Bigger bonus to hit/ dmg and dex, bigger hit to AC and small percentage if your within X number of hex's you might take a hit. At 10th he starts growing extra limbs randomly (1d4-1) dmg 1d6 or 1d4. Theyre fist attacks at 10th. But they are from a raging barbaring who is randomly growing arms and legs from his body. Bigger gain to hit/ dmg/ dex and con, but you take a bigger hit to AC and Int goes way down. The random hit hexes grow one bigger. Hes like stretch arm strong at this point but with multiple arms. Or legs. At 14 he completely in the Warp Spasm. 1d6-1 new appendeges grow from his body every third round. He has the sense of mind to be able to use weapons now so some of these barbarians strap every kind of weapon they can to their body knowing whats coming. Energy crackles about their body doing 1d4 to any touch attacks. 1D6 new appendages grow every 3rd round. AC takes a big hit. All he wants to do is kill. He loses the int modifier but can still lash out at friendlies within 1 hex if they dont make a dex save. He might be wielding a two handed axe in two hands, a longsword in another, a mace in a third, maybe a shield in his 4th or a flail...who knows. Like i said, they arm themselves to the teeth because they kknow once they hit Warp Spasm they can use these weapons. Bonus to hit and dmg, loses dex bonus. Hes too damn big at this point. And hes putting out so much damage, probably too much, i had to try and balance it. He also has to re-roll for limbs every third round so that arm that just popped out of his back might turn into a 3rd leg he can use to stomp with. But anyroad, thats a very brief summery of my barbarian build.
