I tried suggesting just one extra building, and got a lot of negative responses from it-there's a lot of anti-building sentiment going around, unfortunately.

I'd like the ability to create spells that not only have greater effects depending on your path level, but different effects if you're strong enough to actuate them. Like, you could have a spell that creates a cone of wind that stuns enemies be the first effect, but if you have 2 more Water than you need to cast it, it also causes ice damage.

You could even have spells that can be improved if you've got other paths beside the standard one-like casting a Bladewind that, if you've got high enough Fire magic in addition to Earth, the spell does additional fire damage.

It would look something like this:

Bladewind, cost 3 Earth
If caster has 5 Earth plus 5 Fire-each blade does +1 fire damage. Every 2 levels of Earth and Fire beyond 5 (7, 9, 11, 13, 15) grants +1 fire damage beyond that.

Something like that

It wouldn't necessarily be over-powered, because mostly only Pretenders are going to be able to use these kinds of spells, and the really powerful ones might have increased gem-costs associated with them
