Threshold-Based Path Magic

[starslayer]

I haver not played or run a game where the rules were in effect but I did look at them, based on my analysis;

What you'll end up with is a setting where charms are even more important, and your threshold is basically one 'anything' charm in reserve.

Ritual adept becomes less useful (you can only make one charm per thresh regen cycle) being more applicable to the one emergecy cast.

Spells in general which are not charms get used less (which helps prevent the 'a buff for every occasion' effect) it changes the very dynamic problem solving nature of rpm magic into something more along the lines of vanician magic.
