**Energy advantages over mana**

AFAIK, the only benefit of energy is in attaining maximum mana - it helps in nothing else, unlike Diablo. I've reviewed the maximum mana formula and here's my immediate conclusion.

Assuming a Barb reached CLvl99 with no added energy, there'd be an obvious benefit of %mana if it existed, since it's multiplied against a sum which includes item mana, while item energy simply gets added to the end. So item mana, point for point, will be the same or better than item energy, but item energy would only be the same as item mana if no added energy or %mana exists. Can the same be said for all other classes?Facts & Formulae Archive said:Maximum Mana Potential

Formula for calculating the maximum amount of mana a player will have after items, stat points, etc.:

Maximum mana = ((BaseEnergy - StartEnergy + Level - 1) * ClassBonus + ItemMana + StartEnergy) * (1 + PercentMana / 100) + ItemEnergy * ClassBonus

Where:

BaseEnergy = amount of Energy without items

ClassBonus =

Amazon : 1.5

Assassin : 1.5

Barbarian : 1

Druid : 2

Necromancer : 2

Paladin : 1.5

Sorceress : 2

ItemEnergy = total "+X to Energy" and "+X to All Attributes" gained from items

ItemMana = total "+X to Mana" gained from items

Level = character's level

PercentMana = total "Increase Maximum Mana X%" gained from items and skills

StartEnergy = amount of Energy the class starts with:

Amazon : 15

Assassin : 25

Barbarian : 10

Druid : 20

Necromancer : 25

Paladin : 15

Sorceress : 35

Note: The assassin gets 1.5 mana per lvl up and 1.75 mana per point of energy. Therefore this formula is inaccurate for assassins.

The maximum energy from items appears to be: 340 for a Barb, 330 for a Sorc, 325 for everyone else. I suppose there must be an easier way to figure out the ideal amount of item energy versus other mods to attain a healthy maximum other than casting until everything is dead or you run out of mana, with the latter meaning add more. I started by deciding end gear item energy summed with added energy to reach potion critical of 200. Is that a good place to start?
