Hello, i'd like to try a new party thought for an HOF adventure....
I'd like to use 4 characters, want to be able to melee, but don't want to use builds like the ones in the JUPP..
i was thinking about:
1- Half orc: Barbarian (20, for tireless rage)/Fighter (at least 4 for weapon spec)/Sorcerer (about 5 for mirror image)
The sorcerer levels are explained because one other character (the sorc) tought him how to use the basics of the magical power within all of us... ;)
2- Aasimar: Sorcerer (30)

the other two (max 3) spots i'm undecided....i'd like to have a character that makes full use of backstabbing and another a sort of Sorcerer (23)/ Fighter (4) / Rogue (3) that uses spells in close combat...Geedle electric loop, vampiric touch....
any suggestion will be appreciated
Thanks

You'll definitely need a cleric, without spells like raise dead, mass heal or champion's strength the game will be even harder.
For getting the most of backstabbing you'll need a two-handed weapon and as high strength and as many rogue level as possible. But keep in mind that even 100 backstab damage won't do much versus enemies with 500 HP. You'll either have to go invisible, have mirror images or run away afterwards for survival. (A tiefling with a few transmuter levels might be worth thinking about.)
