Asking for some help as I pepper a little Vancian in Spheres of Power

[Niztael]

I'm using Rituals as something almost anyone can do with the optional pricing of Blood Price & Cataclysmic Magic as the general roads to using such magic. Most of the ritual can be done beforehand leaving the last bit to be cast at the end, though anyone can only hold one spell in reserve in this fashion. However I've thought that those with a Casting & a Spell Point pool could use Rituals by spending spell points with a multiple to the spell in spell points. I'm just not sure what that multiple should be to have it still be a tool, but not so prohibitive that is becomes a wasted rule that no one would bother with.

Thank you for your time and input.

You might be interested in some of the feats in Player's Guide to Skybourne, mainly the feats: Spell Dabbler (http://spheresofpower.wikidot.com/general-feats#toc49), and Spell Adept (http://spheresofpower.wikidot.com/general-feats#toc48).

Thank you, perhaps any higher might make the option useless. I did originally think higher like 2 to 3 times level in spell points. The versatility granted is something I was hoping to keep slightly more prohibitive.
