+1
Nothing wrong with a Neutral/Evil Solar far as I`m concerned. You`ll all start out with no memories of anything happening prior to the beginning of the campaign, so any angelic moral code/ethics would go out the window with everything else... And you wont lose your powers to some god`s whims, you`re empowered by your own inner strength (Dont remember what the fluff says about this, but that`s how I`m handling it).
Daedroth:
I love the part about being a blacksmith in a Iron Golem body. Will be interesting to see how you play that out with the amnesia. Frankenstein`s Monster had a nice twist to it... It discovered an affinity for certain tasks as it went along, like playing the flute.
Swim: +5
Yeeeah, right. I would love to see 1ton of solid steel going for a morning swim. On the upside, you dont need to breath, so you can just walk, I guess... Unless its bottomless, ofcourse.
Siper:
Are you sure you did the math correctly on your stats? I keep getting 30p.
Handwave it. Planescape did it.
And I have new candidates!
Tsochar is still on the table.
Daelkyr: MuahahahahaHAHAHAAHAHAHA! The Surgeon from hell. I can spawn Alex Mercer for the hell of it. Point of fact, that's probably the character motivation right there: Why the hell not?
Awakened Basilisk: BFC! I shoot lazor beamsz out of my eyes, people suffer dex damage and collapse! What's not to love? Walking debuff machine. Obviously, since you people have eyes, I'll take carefull gaze to avoid mezzing you.
Gray Shiver Fear the Bug Lich! FEAR HIS FUZZY BODY! Basically a Sorc. But it's a spider living in the skull of a lich!
Also this: In addition, if it ever meets the ones who destroyed the lich to which its skull belonged, it must seek their doom! Long convoluted overcomplicated plans spanning years or more are optional to achieve this.
Basilisk seems like a one-trick pony... Looking at stuff has to get boring in the long run.
Of those, I`d say Daelkyr, tsochar, or Grey Shiver in order of awesomeness.
