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.

For Argos, hammers count as melee for some reason. Frenzy and biotoc enhancement combined came out to me doing a 1.5 million per super use, so I had almost 6 million after 2 damage phases. One person on our team had a staggering 500,000. How do even do that little damage?
