RChu1982: You do what you want, but straying from Bishops, and Humans, seems sub-optimal. You see, Humans get the maximum stats, and Bishops get the maximum credit to 4 spellbooks, in a given level.
It seems fun for me to maximize on those things.
Play how you want, however.
But there's some mice items that Humans can't equip. For example:
* Fey Ring: +10 Speed (good for fast bishop), +20 Stealth (good for keeping the low HP bishop alive)
* Ring of Beasts: +10 Senses (good for fast bishop), +10 Mythology (you *do* want to know which realm the enemies are weak against, right?)
Neither of which a Human can equip.
The Fey Ring is definitely farmable, though the chance of getting it is low, and some of the enemies that can drop it are quite dangerous.
The Ring of Beasts shouldn't be too hard to get. The creatures that can drop it are neutral by default, but can be turned hostile without directly attacking them, and are the dominant creatures in the area. (Do the Rattkin respawn?)
There's also the factors of resistance and that sometimes the right racial choice can get you expert skills significantly sooner. For example, a Felpurr Bishop cab get Snake Speed at level 13; Fairy even earlier, at 12. By contrast, a Human won't get that until level 17, which for me means that I'll get her some Snakeskin Boots before she can fully benefit from them. Getting the skill earlier means it has more chances to grow, especially for something like Snake Speed whose growth is apparently unaffected by your actions.
Choosing a non-Bishop specialist caster has its advantages that I discussed before. In the case of a Priest, for example:
* No need to waste points on Intelligence, Dexterity, or Senses, if I don't need those stats for the build. (It's unlikely that I'll want all three, unless the build involves a class change.)
* Start with 10/11 Divinity before bonuses. Put 5 in at level 1, 3 in for levels 2-4, and you have 24 without having to cast a single spell, which becomes 30 with the primary skill bonus. Next level up, if it's in Priest or Bishop, will allow for Armorplate and Magic Screen to be learned. (I double-checked; the primary skill bonus doesn't change until *after* you pick your level-up spell(s).
* Also, more HP and faster leveling, not to mention prayer.
Valkyrie's advantages over Bishop are significant, due to the class being designed for filling a very different role:
* Far more HP
* Better attack rating, so gets more attacks and swings earlier
* Significantly better equipment options, being able to use almost anything a Fighter can use (the Chieftain's Scepter being the only exception I'm aware of, and that weapon requires killing a friendly NPC and isn't that great damage-wise), not to mention having a gender restriction (male only)), and having access to Polearms, which are one of the best weapon types. This includes the Infinity Helm (absurd HP//Stamina/SP regen) and the Golden Breastplate (15% resistance).
* Primary skill bonus in Polearms, so more accuracy and easier time getting extra attacks and swings. (By contrast, Bishops can't even get that skill, even though there's one weapon of that type they can use.)
* Cheat Death as an added bonus.
* For all that, the only drawback that's not related to spellcasting is not having the bonus to Artifacts.
