Mana Regeneration

Mana, mana everywhere and not a drop to drink. I just found this out recently ... if your mana is completely drained, and you do not have any regenerate mana items, or skill points in Warmth if you are a sorceress, then it will take 2 minutes for your mana to completely recharge. The more mana points you have, therefore, the faster the rate of regeneration.

If you do have a scorceress with skill points in Warmth, or if your character has a +regenerate mana item, your mana will obviously regenerate more quickly. But how much more quickly?

Here is the formulae to figure how many mana points are gained per second:

25 * [[256 * max_mana / (25 * 120)] * (100 + %Mana Regeneration) / 100] / 256

For example, with 900 Mana and level 20 Warmth (+258% Mana Regeneration), we regenerate 26.5625 Mana/second.
25 * [[(256 * 900) / (25 * 120)] * (100 + 258) / 100] / 256
25 * [[230400 / 3000] * (358 / 100)] / 256
25 * [76 * 3.58] / 256
25 * [272] / 256 = 26.5625 mana per second

Too complicated? It is for me ... so here is an easier approximate rule of thumb to use:

(M * R) / 120
Where M = Maximum Mana, and R = (100 + %Mana Regeneration) / 100

So, our example above would look like:
(900 * (100 + 258) / 100) / 120 = 26.85 mana per second

That's close enough for me.
