How to play the run
- Level Sludge first. It is your only attack at the start. Push it to level 5 with upgrade cards.
- Take Power once (+10% damage with every move.) so a golden card turns Sludge into Sludge Bomb (×1.8 damage, +2 projectiles, +2 pierce and bigger).
- Add Toxic Spikes for the hordes. Only your active move fires, so switch to it (1–4, Q/E or tap) when you are surrounded.
- Enter every rift you can. Beating the legendary gives a bond: fuse Sludge with Toxic Spikes so both fire together from one slot.
- Hold Leftovers: You recover 1.5% of your HP per second. Held items drop from chests and bosses; you keep one at a time.
- Before minute 30, stack damage and defense: the Judgment of Arceus sends ever-stronger legendaries until you fall.
