Looking through my adventurer list, I saw that I can make a D4 Olive to be a good chest opener (already have D1 Rinne round-trip, D2 Gold Maiden, D1-3 Barbara round-trip, D1-2 Milana). Dex, Speed, or Luck as the boon for Olive's fighter/thief (I probably need to check their thief stats instead of fighter)? I was going to end up with an extra CC from the 6 on the mission pass (using 5 on Gerulf, Yekaterina, Alice, Gold Maiden, Chloe) assuming none show up on the weekly shop.

Also, where should I be dumping the 400xp from Elise's Wild Strike inherits?
