what's better in wiz8? no mage or 2 or 3 or 4 mages? because 1 is certanly a waste of space early - mid game. you'd think a pair of fireballs would be enough for big weak grps but they're not.
and how does stealth work? i didn't see a hide button. does it just passively increase armor value or am i blind?
Mage alone is kinda weak, they're most useful for buffs, web, and freeze spells. Whipping rocks is probably their best AoE damage spell until Nuclear Blast, but damaging spells in general are kinda worthless at that level.
I always use a Bard and a Bishop, plus a hybrid or two (Samurai, Valkyrie, Ranger, Monk) but they rarely get much use as casters. A single Bishop is more than enough to satisfy all your spellcasting needs.
Stealth gives +1 AC per 10 ranks, there's no "Hide" ability from skills. If you want to sneak by monsters you have to use Chameleon.
thank you but aside from the stealth mechanic your answer is a bit simplistic. would it not be viable to cast 4 fireballs at "normal" enemies and kill all in one round early-mid game or at least till i hit 100 int and have all spells and then multi class them to something else? am i wrong to assume i can continue to cast spells and continue to skill power cast after multi classing?
Blasting enemies with 4 fireballs in early/midgame will be effective, if you don't mind resting after every battle (which resets the enemies).
You can continue to level skills after class changing only if the new class also naturally has the skill. So if you multi-class a Mage to a Samurai, you will be able to keep leveling Wizardry. If you switch them to a Lord, you will not be able to learn Wizardry anymore, not from normal level-ups or training. You will be able to increase the Realm skills, because the Lord is also a caster, but you will only be able to increase Divinity instead of Wizardry (Realm skills mostly affect Spell points and casting success, only have a small effect on learning new spells). If you switch a mage to a non-caster class like Fighter or Rogue, you don't get any more magic skill increases at all. You won't get free spells from leveling either.
Powercast will increase regardless of class because it's based on stats rather than class. If you're willing to skill up Wizardry to 90 (max needed for 7th level spells) you can switch classes BUT class levels are also a requirement for learning spells. I'd have to check but I think you need at least 18 levels in a casting class to get 7th level spells, higher for hybrids. Int has no effect on spell learning at all.
