Floor 4 Guide: Ganesha's Revenge
What this page helps you decide: whether your team has the role coverage and placement plan to attempt each Floor 4 room, especially Burning Throne and Shadow Courtyard.
Floor 4, Ganesha's Revenge, moves from three-lane rooms to Burning Throne's seven entrances and ends with a reported 1,125,000-HP Shadow Ganesha. Every numeric row below comes from one Rubenakayoshii community guide published August 4, 2026. The placement advice comes from the same channel's August 7 Room 5 strategy video. Neither is an official developer stat table, so verify values in the current beta build.
Evidence boundary
Room names, lane counts, waves and HP are transcribed from WSIfdqA6Ja4 by Rubenakayoshii, published 2026-08-04. The strategy summary comes from BG3CrpQ_V8I by the same channel, published 2026-08-07. These are useful, detailed community sources but not independent confirmation or developer documentation.
Why Burning Throne is a placement check
Seven entrances stretch early coverage while the wooden-platform-only restriction reduces legal placement. A unit with excellent paper DPS can still underperform if its range misses several lanes. Test at normal speed before committing to a fast farm layout.
Room 5 role plan
The community strategy places AOE at crossroads and T-junctions, beam units in the middle or back for longer firing windows, and long-range units near the center. Its example team was Torment, Demon Prince, The Duchess, Deaf Gunner and Demon Cat; the transferable evidence is the role and placement pattern, not a claim that those five are mandatory.
Step-by-Step
- Treat Room 1 as the entry damage check: the source reports Angry Oni at wave 8 with 162,000 HP and Water Oni at wave 15 with 540,000 HP.
- Keep multi-target coverage for Room 2's wave 10 group - Yellow Oni, Red Oni and Oni Warlord - before the 594,000-HP Shadow Oni at wave 17.
- Cover both exits in Withered Garden. The source reports Empress at wave 9, Yellow and Red Oni at wave 14, then Rot Oni at wave 18 with 657,000 HP.
- Plan Burning Throne around terrain, not only Fire Oni's reported 738,000 HP. The room has seven entrances and the source says units can be placed only on wooden platforms above lava.
- Enter Shadow Courtyard expecting earlier bosses to return before Shadow Ganesha at wave 21. Preserve boss damage instead of spending every upgrade on the first rush.
- Use the community strategy as a role checklist rather than a hard gear gate: AOE at crossroads, beam units in the middle or back, long-range coverage near the center and strong single-target damage for the finale.

Tips & Notes
- The August 7 source recommends strong Mythic units with Devil's Pact and at least one Secret unit. That is one creator's successful setup, not proof that every clear requires the exact rarities or curse.
- If you do not own the source creator's lineup, preserve the roles: AOE, beam, long range and boss-focused single target.
