Question of a new player about MP-regeneration

[Coldea]

Shroud of Saints
Shroud of Saints is a White Mage ability that recovers 1090 MP regardless of your MP pool or other stats. When used it will give you back 1090 MP spread over 15 seconds or 218 MP every 3 seconds.

Shroud of Saint does NOT gives a flat amount of MP, it has a potency, which means it varies with your weapon damage. It feels 'flat' because you dont change your weapon very often.
