Just my rough guesses on Aranea PCs
MM entry: Dex +4, Con +4, Int. +4, Wis +2, Cha +4. (now the +8 makes some sense. Ouch!)
A more toned down version of suggestions:
Suggested Racial traits: (this may take the ECL down to +5)
An option of racial bonuses to make the race less outrageous. The three version could even be different breeds.
Str-2 , Char +2, Int +2 (I find it odd that the designers don’t allow for any strength penalty to balance out “social/mental” bonuses.): standard Araena PC
Str –2, Dex +2 “Trapdoor” thief breed
Str –2, Con +2 “Wolf Spider”
Size: Medium
Speed 40 ft, Climb 20 ft (alternate forms only)
Darkvision: 60 ft.
Racial skills: +4 to Climb (Alternate form only), +2 Concentration, Craft +2 (Weaving), Escape Artist +2
Web: as per MM, but based on Con ability bonus per times a day.
Poison: as per MM, but based on Str ability bonus per times a day.
Alternate forms: as per MM, but based on Con ability bonus per times a day. Minimum once per day.
