Path of Idle Doom guide: what the final three stages demand
Doom is a roster check, not a single team check. Any hero who finishes a Doom site gains Fear and cannot be sent to another site in the same stage. Dread has 7 sites, so a full Dread run needs seven separate teams that never share a hero.
That is the wall most players hit, and no amount of gear on one team gets around it. Doom opens after you clear chapter 20, Rift-Star Expanse.
The three stages
| Stage | Sites | Concurrent teams | Entry per site | Reset cost |
|---|---|---|---|---|
| Dread | 7 | 1 | 1 Faith Skulls | 1,000 Bone |
| Suspicion | 4 | 2 | 2 Faith Skulls | 2,000 Bone |
| Frenzy | 3 | 3 | 3 Faith Skulls | 4,000 Bone |
Every stage fights level 100 enemies, but the attribute level rises: 110 in Dread, 115 in Suspicion, 120 in Frenzy. Since crit, dodge and defense resolve against a level threshold, those attributes are worth progressively less across the three stages while resistance keeps its full value.
A clean run of all three costs 24 Faith Skulls: 7, then 8, then 9. Faith Skulls drop only from chapters 19 and 20, at a base 0.10% to 0.15% per roll.
Advancing to the next stage or resetting the current one clears Fear from the heroes who used it, so a reset buys your roster back at the price in the table.
What each stage permanently gives
| Completed | Equipment corruption cap | Hero level cap bonus | Cumulative |
|---|---|---|---|
| Dread | 1 | +3 | +3 |
| Suspicion | 2 | +3 | +6 |
| Frenzy | 3 | +4 | +10 |
The hero level cap bonus is permanent and cumulative, so finishing Doom raises the cap by 10 in total. The corruption cap controls how far a piece of equipment can be corrupted; the Stele pages cover corruption outcomes and prices.
Enemy power climbs as you clear
Within a stage, enemies get an attack and health bonus that grows with the number of sites you have already finished.
| Sites completed | Dread | Suspicion | Frenzy |
|---|---|---|---|
| 0 | +8% | +8% | +10% |
| 1 | +10% | +12% | +14% |
| 2 | +12% | +16% | +18% |
| 3 | +14% | +20% | complete |
| 4 | +16% | complete | |
| 5 | +18% | ||
| 6 | +20% |
The bonus applies to both attack and health. Each stage ends at +20% for Dread and Suspicion, and Frenzy finishes at +18% across its three sites.
The practical reading is that your weakest team should go first. Site order is sequential, the penalty is smallest at the start, and by the last site you are fighting enemies with a fifth more health and damage than the first one had.
Who you fight
Dread and Suspicion draw from a shuffled set of chapter themes taken from chapters 1 to 10, and each site’s boss comes from its selected theme. Those are the same ten bosses you met in the campaign: King Gollum, Giant Tree Warden, Kuru the Warden, The Butcher, Vera the Ranger, Ice Lord, Mushroom Champion, Blazemane Chieftain, Demon Hunter and Nexus Prince Harvey. Their skills and drops are on the enemies pages.
Frenzy has three dedicated bosses instead: Wrathful Will, Cold Will and Destructive Will. It also shuffles three area restrictions independently of the bosses, so there is no fixed boss and restriction pairing to memorise. You find out what you are dealing with when the stage generates.
All three stages drop Set Chests alongside equipment chests, gold, blood and souls.
Preparing for it
Build seven teams before you start Dread, not one good one. The seat roles in team composition still apply to each of them. Souls from chapter 19 and 20 are the fastest way to level a bench: at chapter 20 they average 116,667 experience each. The farming guide has the soul table.
Weight resistance over defense on all of them, for the attribute level reason above. The attributes guide shows how far apart those two scale by stage 3.
Keep bone in reserve, and read the resource economy guide if bone is already tight. A reset costs 1,000, 2,000 or 4,000 bone depending on the stage, and getting stuck on the last site of Frenzy with no bone left means the run stops there.
