Is Frost Moon Terraria even possible to beat in time?
I already have post Moonlord gear including the Meowmere (which I have found extremely useful for taking out many weaker enemies in the earlier waves), and the Terrarian which I use against the bosses for it's high DPS. But it still wasnt enough.
The only guides I can find online are just general boss strategies like "use campfires/heart lanterns", but dying isn't the issue.
And all of the discussion boards are several years old and talk about "reaching wave 15", but unlike the pumpkin moon, there is apparently 20 now. I can consistently reach 15 or 16 by the end of the night, but always run out of time, and I don't see how it's even possible to reach wave 20 in time.
Is it even intended to be possible?
By the looks of https://www.youtube.com/watch?v=J-HWtu01zds , yes. Towards the end is where they manage to finish it.
The poster of that video tried a few strategies, but it seems the one they went with that allowed them to beat all 20 waves was setting up a https://terraria-archive.fandom.com/wiki/Skybridge#:%7E:text=A%20Skybridge%20can%20be%20constructed,map%20or%20the%20desired%20location. and using the https://terraria.fandom.com/wiki/Zenith sword as their main weapon of choice, among other things.
They originally tried a few other things, such as an arena with traps, but trap damage caused the NPC's to be momentarily invincible, lowering your overall DPS, making it very hard to finish all 20 waves.
