But if mage is 1 level below required and spell costs no more then 1 gem

I think there's a mistake here; the right answer is "mage 1 level below the required spell level and the spell cost in gems +1 is less than or equal to mage level in that path". So you can cast level 4 spells that costs 2 gems with level 3 mage ("Living X" spells are an example).

Right, my mistake. 2 gems is the cap.

I don't think so, it's supposed to be that mages can spend at most their spell level in gems at a single spell.

A level 3 mage would be able to cast a level 4 spell if it costs 3 gems or less (up to their level in casting + 1 to increase their level for that specific spell), but not a level 4 spell that costs 4 or more.

As I read it your comment should be that "the cap is the caster's level in the path, +1 to increase his effective casting level."; or what Dimaz said.

Am I wrong?
