Alternative magic system for DnD

[Ra-Tiel]

While I think that's a great innovation, and used something similar in my invented (now defunct) magic system myself, I think it is all the more reason a caster should be able to dismiss most of his spells at will. Standard D&D doesn't make it dismissable because it's not something that normally drains resources; a caster would have little reason to get rid of it, even if he no longer needed it.

I definitively see your point and if building a system from the ground up I'd strongly agree with you. However, I'm not really keen of modifiying and double-check every spell's duration, and recheck to avoid abusing, I'm leaving it as is. Also, does a caster really have unlimited and absolute control over the forces he sets loose? I don't think so, at least in DnD.
