How to calculate base mana pool
As stated above, the base mana pool is only dependent on your class. Each race will have the exact same base mana. The calculation is quite simple.
Código:
Base Mana = Max Mana - Mana From Intellect
Notes:
Mana From Intellect is given by hovering your mouse over the Intellect stat on your character screen. The part that says "Increase Mana by XXXX" is how much Intellect is boosting your max mana.
Some talents boosts your max mana by a flat percentage. You should remove the effect of this talent before doing the computation. So if it says you have 11000 mana and you had +10% mana then you would divide 11000 by 1.1 before you subracted the amount of Mana it says you gain from Intellect.
Código:
Example : Kalium - 70 Human Warlock - Total Mana 8695. Intellect Increases Mana by 5824.
8695 - ( Talents = 0 ) = 8695
8695 - 5824 = 2871 Base Mana Pool
As a sanity check, it can be noted that most spells in the WotLK beta and PTR have moved to costing a percentage of base mana. This can make it very easy to verify that the numbers are correct.
For example, at level 70, Rank 7 Mind Flay on a level 70 Night Elf Priest without Focused Mind nor Shadow Focus costs 9% of base mana which in game shows up as 235 mana. 9% of 2620 is 235.8 (the numbers all get rounded down).
