Skills with the Passive tag need to be equipped at special Passive Skill slots.
Passive Skills have various powerful effects. Choose Passive Skills that suit you best.

When certain skills are equipped (mostly Aura Skills and Triggered Skills), Mana will not be deducted when players use these skills. Instead, a portion of their Mana will enter an unusable state as the cost of using these skills. This is referred to as Sealed Mana. Similarly, Sealed Life is the process of sealing Life.

The sealing process does not change the Max Mana or Max Life.

A fixed amount of proportion of Mana and Life can be sealed. The amount of Mana or Life sealed is also affected by other skills and affixes.
