However, while a character with 600 mana and another with 1,200 mana will take the same amount of time to regenerate from zero to maximum mana, the former will do so at a rate of 4 251/256 mana per second while the latter will do so at a rate of 9 246/256 mana per second. Ideally mana regeneration should equal mana consumption to allow skills to be used indefinitely, although practically this normally isn't necessary since skill usage is finite, and there are intervals between skill usage which allow mana to regenerate without consumption. For example, a skill like Tornado with 10 mana cost and 10 frame cast rate consumes 25 (10 * 25/10) mana per second when cast continuously: a Druid with 3,000 maximum mana would regenerate 25 mana per second, allowing him to cast it indefinitely. However, while a Druid with just 1,500 mana would only regenerate 12.5 mana per second, it would take 120 (1500 / (25-12.5) ) seconds or two minutes to run out of mana when casting continuously, which shouldn't normally be necessary for that length of time. Alternatively, Regenerate Mana 600% would allow the Druid to cast indefinitely with as little as 434 maximum mana: 25 = 25 * [ [256 * Maximum Mana / (25*120) ] * (100+600) /100] /256 256 = [ [256 * Maximum Mana / 3000] * 700 /100] {256/7} = [256 * Maximum Mana / 3000] Maximum Mana = {37 * 3000/256} Maximum Mana = 434 Shrine Mana Recharge Shrine applies Regenerate Mana 400% to player who activates it.
