Dr. Beck-Style Guide: Shi-Nek
Shi-neks are itty-bitty undead slug-foot-things that form when wendigo feet burn off... yeah. One of the stranger ideas I've ever had. Anyway...
Ability Scores: Shi-neks gain a +2 bonus to ALL of their mental scores, as well as a hidden +2 to Dexterity from their size. So what's the downside? An absolutely massive -6 to their Strength. Shi-neks are never going to excel as melee combatants, but they're decent at range, and they shine as any spellcaster. Since they're undead, they don't have a Constitution score.
Size: Shi-neks are Tiny. While this does give them a +2 to their AC, +2 to hit and a hidden Dexterity bonus, it also means that they have no natural reach. You have to move INTO enemy squares for melee combat, which provokes attacks of opportunity. So what are you doing going into melee as a shi-nek?
Type: Shi-neks are undead, so they don't have a Constitution score. Everything that's normally based on Con instead comes from Charisma, so you'll want to keep that fairly high. Also, if your character dies, you can't be raised, so always keep in mind that retreat is an option. In addition, mental effects would normally have no effect on them, buuuut...
Fear Response: They have this trait. Not only are they susceptible to mental effects, they actually take a penalty on saves against fear. However, this does mean that the little feety people can make use of morale bonuses, so cavalier banners and other such effects still work on them.
