I don't understand how spell slot progression works with a multi-class character.
For example, if I had a level 3 melee class, then decided to go multi-class caster, how does the spell slot progression work? Because my character is level 3, does that mean I have access to level 3 caster stats as well?
That is, would I get level 3 amount of caster slots, because my character is level 3, or would I only get level 1 caster slots, because I'm a level 3 melee, but only a level 1 caster?
Does it work the same way in reverse? (Level 3 caster multi-class as a melee, would I gain level 3 or level 1 abilities/skills?)
