You can stack ALL resist with specific elemental resists in order to trigger the momentum loss. For instance, if you had Sayakana and fully-ranked Golden Glow active with Brighter Darkness (20% ALL + 5% Light), anyone who tries to smack you with Light damage will trigger a RESIST message.

Given that all other nonspecific resists, such as Physical Resistance/Magical Resistance, do not cause momentum losses, I'm inclined to believe this is a bug.

[MegaBlues]

General Physical and Magical Resistance are Damage Resistances (I.E. Black Knight and Void Assassin Stuff), which work differently (and are accounted for after elemental and statwise resistances)

Resist ALL counts as an elemental resist.

It's not a bug.

[Rendar]

Black Knight and VA stuff counts as damage reduction.

Damage Reduction is different from Damage Resistance.

Damage Resistance applies before Stat Resistance.
Damage Reduction applies after Stat Resistance.

Sayakana+Golden Glow+Brighter Darkness are all RESISTANCE effects that provide for 25%.

This is working as intended.
