For project slayers 2 flame breathing, find Flame Trainer Rengu on the roof of a large wooden building near the Rengu boss area, past the Forgotten Ruins. Bring Level 25, 10 Demon Horns, and Wall Climb before starting training.
Flame Breathing is a close-range Breathing Style centered on powerful singular sword strikes, often from a high stance. Its techniques visually create and manipulate fire, but its known move details are not officially confirmed for Slayers 2.
Trainer location
- Start from the Windy Peaks and Mistfall Harbor side of the map.
- Travel through the Wilderness toward the tall red wall.
- Continue past the Shinora boss area toward the long bridge.
- Cross the bridge, use the water route, and climb the cliffs toward the Forgotten Ruins.
- Find the tall wooden building near the Rengu boss area and climb onto its roof.
Look for the name tag “Flame Trainer Rengu” and a chat prompt. Searching only at ground level can make the trainer seem missing.

What you need
| Requirement | Detail |
|---|---|
| Level | 25 |
| Materials | 10 Demon Horns |
| Traversal | Wall Climb skill node |
| Training start | Speak with Flame Trainer Rengu |
Demon Horns are reported to drop from demons. Collect them before making the rooftop trip so you do not need to repeat the route through the wall, bridge, water, and cliffs.
Wall Climb is important because the route includes a tall red wall and stacked stone cliffs. Double Jump may also make travel easier.
Training progression
Reaching Rengu and beginning training are separate steps. You can locate the trainer before meeting every requirement, but training begins only after the listed conditions are met.
Reported progression includes:
- Speak with Flame Trainer Rengu.
- Complete his quests.
- Defeat the trainer’s trainee.
- Beat Slayer Exam and raise Flame mastery to obtain every move.
You do not need to fight nearby bosses just to reach the trainer. You can pass through the Shinora boss area and continue toward the bridge and Forgotten Ruins.

Known moves
The following move list comes from an earlier Project Slayers reference and is not officially confirmed for Slayers 2.
| Mastery | Move | Key | Effect |
|---|---|---|---|
| 1 | Rising Scorching Sun | Z | Upward arcing vertical slash |
| 18 | Unknowing Fire | X | Dash into a horizontal slash |
| 26 | Blooming Undulation | C | Defensive pose with burn damage |
| 32 | Blazing Universe | V | Leap into a downward slash |
| 47 | Flame Tiger | B | Dash and flaming tiger slashes |
| 59 | Rengoku (Purgatory) | N | Dashing slash with a ground cut |
Rengoku (Purgatory) also reportedly requires defeating Rengoku as a boss. Flame Breathing reportedly has no ranged moves, so expect to close distance instead of relying on long-range attacks.
Is it worth it?
Flame Breathing fits players who prefer decisive melee attacks, vertical slashes, dashes, and fire-themed sword techniques. It may be less suitable for soloing Final Selection if its reported lack of ranged moves applies in Slayers 2.
