What is Thought Experiment?
Thought Experiment is Silver Palace's premier permanent, story-gated combat gauntlet. It unlocks right away after clearing Main Quest Act II, Scene II: 'The Constabulary' and is accessed through Game Menu > Agenda > Challenge > Thought Experiment.
Unlike open-world encounters, Thought Experiment is structured around high-octane burst execution. The built-in Dream Enhancer modifier provides all operatives with a flat +20% ATK boost, and starting with ready-to-fire Ultimates lets you open fights with coordinated elemental detonations.
Mode 1: Ongoing Project (Rooms 1 to 10 Breakdown)
Ongoing Project is a linear 10-room ascent where enemy levels scale from Lv. 19 all the way to Lv. 75. Floors 1 through 4 test a single team, while Floors 5 through 10 require two independent squads:
| Room Tier | Squads Required | Total Stage Clock | 1★ / 2★ / 3★ Thresholds | Highlighted Element RES |
|---|---|---|---|---|
| Rooms 1–4 | 1 Squad (Partner Team) | 240 Seconds | 60s / 110s / 150s remaining | 20% (Regular) / 30% (Room 4 Elite) |
| Rooms 5–7 | 2 Squads (Top & Bottom) | 480 Seconds | 120s / 220s / 300s remaining | 20% (Regular) / 30% (Room 6–7 Elites) |
| Rooms 8–10 | 2 Squads (Top & Bottom) | 480 Seconds | 120s / 220s / 300s remaining | 40% (All Bosses) |
The Room 8 Boss Cliff & Dual-Team Lockout
Three critical mechanical shifts occur as you ascend into the upper half of Ongoing Project:
- No Duplicate Operatives (Rooms 5–10): Each floor splits into a Top half and Bottom half. You must field two discrete 4-character squads (Partner Team and Partners2). An operative used in Team 1 can't be selected for Team 2.
- Highlighted Attribute Resistance: All enemies have a baseline 10% RES to all elements, plus a highlighted 20% / 30% / 40% RES to one specific Reactor Attribute displayed on the briefing card. Bringing a DPS matching the 40% resistant attribute will drastically extend your clear times.
- Consecutive Boss Showdowns (Rooms 8–10): Mob waves vanish entirely in favor of standalone bosses with inflated Stun bars. Ongoing Project 10 culminates in a brutal dual-boss gauntlet against Soulless Lord on the Top half and "Manager" & "Supervisor" on the Bottom half.
Mode 2: Brainstorm (Bi-Weekly Endgame Boss Rush)
Once you conquer all 10 rooms of Ongoing Project, you permanently unlock Brainstorm. This bi-weekly endgame mode consists of a compact 4-room boss challenge centered around enhanced variations of the Room 10 boss pair (Soulless Lord and "Manager" & "Supervisor").
Bosses in Brainstorm feature randomized tactical affixes and shifting elemental resistances every rotation, requiring versatile roster depth to claim the full crystal bounty.
Complete Rewards Matrix (Depth vs. Brainstorm)
Thought Experiment represents one of the largest crystal reserves in Silver Palace:
