Do Reserves contribute to Luck?

[alleryn]

Luck increases research drops, but do only the first 5 active party members' luck contribute, or do any additional "backup" party members count for luck as well?

(Note: Norn has Luck:0 but Luck:30 under her passives, so she might work differently than others?)

As far as I'm aware all side party member contrabute their buff/stat applications

Unless I'm horrendously wrontif so my bad

[Kite Sumane]

The luck of all party members contributes to research drop amount. It does not matter if they are in the front 5 or not.
