What I meant by 10 seconds is that you have to stand still for 5 seconds and then spend 5 seconds actually regenerating runic energy.

If you want to keep people from just spamming their abilities, use energy and then have things that cost 120 and stuff. Despite its simplicity, the energy system is very flexible, and I really think you should consider alternative applications of already-implemented resources before going and making a whole new one.
