Game Description: Occasionally reduces spells' MP cost.
Job Traits are always active.
Further Notes:
The Conserve MP job trait is equivalent to "Conserve MP +25".
With a base activation rate of 25%, Conserve MP allows you to retain approximately 7 MP for every 100 MP spent. The actual amount retained may vary.
Effect Overview
When "Conserve MP" activates, the cost of the spell will be reduced to n/16 * (original cost), rounded down, where n is an integer ranging from 8 to 15. All possible values of n have an approximately equal chance to occur. Thus, each activation of Conserve MP save 28.125% of MP cost on average.
Equipment that gives "Conserve MP +X" increases the activation rate of Conserve MP by approximately X% of spells cast. E.g. Conserve MP +5 in combination with the Conserve MP job trait will give a net activation rate of 30% of spells.
Conserve MP will not allow you to cast a spell for which you would otherwise have insufficient MP to cast.
when used in tandem with Parsimony or Penury it is technically possible to have a spell cost 0 MP
Conserve MP gear can be removed MID CAST and you will still have the effect of the enhanced conserve MP rate, it simply needs to be equipped when your casting begins.
