Money Spend Per Mana
For this table take in consideration that:
 * You will use rings completly.
 * You will drop empty vials.
 * You will buy the Ring of Healing from players for 1,000-2,000 gp and the Life Ring from the shop, but you wil hardly get Ring of Healing for that price on most worlds.
 * You will hardly get mana fluids now.
