This lag-fest spark-spamming winterfest mission doesn't seem as hard as it can get. I have a suggestion for a 'new year' themed danger mission.

1. Have a 5x5 tile room.
2. 8 rocket puppy spawners surrounding the spot. Only Callahan/Iron Slug charges can hit them but they are aggrovated instantly when spawned.
3. Have shadow fire spawners surrounding the field with water in the middle.
4. Surrounding the water spawner, have a Shock Greaver spawner, Trojan Spawner, 2 Mender spawners, 2 overtimer spawners (fire and poison), a silkwing spawner and a deadnaught spawner.
5. On top of all that give all the monsters immunity to stun, poison, curse, fire and freeze.
6. Let snow randomly fall from the sky that slow knights down.
7. Also include x4 swamp seeds out of the room in each corners, so the middle is effected by all 4 swamp seeds.
8. The boss will be a 'Cursed Knight' wearing a triple max all status-immune jelly set.
9. The boss' blitz shoots out rainbows with a random chance of any offensive strong status in this game.
10. The boss drops one token. Collect 100 to forge the new 'reskin' Ancient Plate Sets along with 'Winmillion' and 'magnus' line reskins. Crafting them will cost 25k cr, 3 Eternal Orbs and no life.
