Actually,
that's the issue I presented in this thread - the order of side-content pre-Cultist.
Is my best score in Frost Moon with Tsunami? Yes.
Could Snowman Cannon help with Fishron? Probably, didn't try it first hand.
Did I have more problems with both Moon events than with Fishron and nighttime EoL? Yup. Still can't reach wave 20 Frost moon.
Now you can add that you not only have Empress of Light in this mix, you have her Normal AI vs Expert/Master AI versions, and then you have the night and day drops, and I'm pretty sure Terraprisma would drastically help with Fishron, the all Frost Moon's 20 waves, and probably later with Cultist, Celestial events and probably even Moon Lord.
Chronologically, Fishron was once the final boss (just before 1.3). And Frost Moon was the final event literally before Fishron. Both were optional.
There's also the Pumpkin Moon, and Tier 3 OOA.
In my case, Fishron ain't that hard with some yellow water, homing hatchet/holy knight's smithing tool, and a flying wooden boat. Which I applied to nighttime EoL. And Martian Saucer. Okay, I did use Vampire knives too, but hey, I didn't bother with getting a Scarf.
It actually is. I
personally couldn't do it with Spectre + Staff of Frost Hydra + Razorblade Typhoon and Charged Blaster Cannon alone, and I didn't even do tiers 1 and 2, so there were a LOT of fail runs to get some Medals.
My first win was with Dark Artist + Flameburst and/either/or Ballista + Frost Hydra + Typhoon + Charged Blaster Cannon + mage accesories, wings, mount, potions (+hot swap Treasure Magnet). Arena is flat Asphalt with few Actuator-able blocks above the crystal as a precautionary "hat", generic regen stuff, and some Platforms.
But I think it's doable if you're a bit more git gud than I am without any gear from Tavernkeep, at least that's how I farmed my Medals. Either Betsy killed me, or mobs got to the crystal while I fought her.
Stellar Tune helps here if you can navigate and keep Betsy on screen, better than Typhoon IMHO. Though a stray Typhoon will kill the mobs.
Then again, I didn't even try Flairon or Tsunami in OOA. Or Starlight+Vampire knives. Or anything else than a mage
And I'm mostly a melee player.

To others reading this part of the thread - OOA, an event that actually scales depending where you are in HM, has pretty much useless Tier 3 drops. Aside from armors and Betsy's Wrath as replacement for Golden Shower, there ain't much.
