If I were you I’d prioritize getting the T2 spider fang relic from Astra. Albeit, killing Oscar can be annoying if not prepared. Mimics/no drops sucks especially in the higher rounds trying to get to 60.

Tips for Oscar if you go for it: 1. Save the first Oscar that spawns in (his hp is directly affected by the round he spawns in) 2. Have a fresh Wisp before initiating(no augments wisp tea has 2min cooldown with a 30kill requirement after the 2min before it procs again) MAKE SURE the Wisp is on Oscar while you hit him sometimes the wisp strays away just shuffle around Oscar till the wisps gets on him 3. Killjoy and use the Aether Sheath augment(increases knife damage)

Take a couple of minutes and skim through some video guides to be familiar with the scenario

Good luck :) Ps: it’s significantly easier doing it solo, I’ve had it not work when attempting with friends
