Status System Save Roll Formula

Major: (MajorInflictStatistic - MajorResistStatistic)/5, minimum -20, maximum +20
Level: (InflictLevelStatistic - ResistLevelStatistic)/2 (no cap)
Minor: (MinorInflictStatistic - MinorResistStatistic)/10, minimum -10, maximum +10
Additional Modifiers: (NetInflictModifiers - NetResistModifiers) (no cap)

Save Roll Difficulty = 51 + (Major + Level + Minor + Additional Modifiers)

Resist Status Roll = Random # Roll (1,100)

If Resist Status Roll < Save Roll Difficulty, the status condition is applied. Otherwise the status condition is not applied.

The monster can resist each with a save at a +0 bonus (inflict with END/LUK, resist with END/LUK on both).

The Devs haven't provided any info about save stacking mechanisms for status conditions, it may keep track of the saves for each instance or the most recent application overwrites the earlier ones similar to how higher level damage statuses don't stack with lower level ones, but replace them.

As long as the status potence is present when the save is made on a turn, the status condition benefits from it.
