Before you go

Where: the storm drain on the Trailer Park's south side.
2 to 8 of you go down, the grate shuts, and what's down there is yours. Like the Crypt, it has three depths on one map.

Depth	Door opens at	The kings want	Ante each	A clear pays each
The Undercity	Combat 65	about Combat 75	1,500	12,000
The Deep Drains	Combat 78	about Combat 88	2,000	12,675
The Rat Court	Combat 88	about Combat 97	2,500	13,325

How a run works

Four chambers side by side: the Outfall, the Drains, the Cistern (a chest to restock from, and the sluice wheel) and the Rat Court.
Each grate lifts when its tunnel is clear. The Court's lifts at the wheel, once everyone still alive is in the Cistern.
Expect sewer rats, rat knights, rat crossbowmen who shoot from three tiles away, drowned plumbers and sludge.

Watch the floor

Sludge (the green pools) eats 4% of your health a second while you stand in it. Walking through costs nothing.
The gutter channels carry anyone standing still in them a tile downstream about every second. Cross at a walk. Stop to fight in one and you'll be washed away from the fight.

The Rat Parliament

Three kings: the Speaker (slow, hits hardest), the Whip (quick) and the Backbencher (won't fall over).
They share a vote. When one falls, the other two get angry and hit about a third harder.
If the other two aren't both down within 9 seconds, the fallen one is re-elected at half its health. Bring all three low together and finish them close together.

Rewards

When the last king falls, everyone who earned the clear opens their own chest: the clear's tickets, then two to six more things: drinks, dinners, clovers, scrolls, casino chips, a horseshoe, now and then buff gear.
The Rat Prince, a pet: 0.5% of chests in the Undercity, 1% in the Deep Drains, 2% in the Rat Court. Only the Rat Court can give its Legendary, the Rat Emperor, 0.25% of chests.

Gutterplate come from this chest and nowhere else: Gutterplate helm, Gutterplate cuirass, Gutterplate greaves, Gutterplate gauntlets, Gutterplate sabatons. Melee 90. Plate with a little more defence than singularity and its Melee damage; all five: every kill heals you 5% of your health. A chest never gives you a piece you already have (worn, in your bag or in your bank); own all five and that roll is tickets.

Limits

Three paid clears a Chicago day each. After that a clear pays 25% and three rolls with no gear, set or pet.
Anyone who did under 10% of the damage to the kings gets half pay.
The fastest clears are on the Hiscores.
