I was originally thinking of multiclass ING into something wis or chr based, but then I rolled stats lol

If we're going to start as lvl 2, how does that affect our starting wealth/gear?

You might already know all this but in case you don't... as long as you have a 13 in all the prime stats of each class, you can multiclass.  Even 1 level of cleric or bard would give you Cure Wounds spell.  And your caster level is your character level.  So you might only be Cleric 1 but if you're a Wizard 10, your caster level is actually 11 allowing you to use higher level slots to increase the healing.  It's not a bad deal.

But stat bonuses/feats are based on class level.  So you could create a character that never gains a stat bonus if every class you took was never higher than 3rd level.
