Punching the pots/plates in Ca'our's room triggers the "Triumphant Rush" weapon damage buff. This is actually super useful for DPS if you're doing Wardcliff strat as there's a bunch of pots up on either side of the boss plate.
Discovered this with my clan last night and it ended up being super helpful. Easy one-phase if you have Melting Point and an Empowering Rift.

Useful EoW tip. The triumph buff + a tether on Argos=1 mil damage per celestial GG shot.
