Flame Breathing is one of the heavy-hitting Slayer styles in Slayers 2, built around wide sweeps and burn damage that stack up against high-HP bosses. Unlocking it takes more than finding the trainer. You need a specific level, a Wen fee, a stack of Demon Horns, and a run of six training tasks that end in a boss fight.
Quick answer: Reach Level 25 with 6,000 Wen and 10 Demon Horns, find Flame Trainer Rengu atop the large wooden house in Forgotten Ruins, and complete all six training tasks.
Flame Breathing requirements in Slayers 2
Rengu will not start the training until your character clears every entry below. Bring all three before making the trip so you can begin immediately instead of backtracking to farm.
| Requirement | Amount | How to get it |
|---|---|---|
| Level | 25 | Quests and defeating enemies |
| Wen | 6,000 | Quests, mobs, and map enemies |
| Demon Horns | 10 | Hoyuzu Subordinates and the Hoyuzu Boss |
Level 25 is only the floor. Level 45 or higher makes both the farming and the training far smoother, since the materials and the final fight punish an underleveled character. If a higher-level friend can carry part of the work, you can attempt it sooner.

Add to Google Preferences →Where to farm Demon Horns
Demon Horns drop only from two enemies, and both live inside the waterfall near Bamboo Grove. Ten horns is a light target compared with some other styles, so this step rarely takes long once you are the right level.
| Enemy | Drop chance | Horns per drop | Recommended level |
|---|---|---|---|
| Hoyuzu Subordinate | 30% | 1 | 40 |
| Hoyuzu Boss | 50% | 3 | 50 |
Head inside the waterfall by Bamboo Grove to find both. Prioritize the boss when you can survive it, since three horns per successful drop clears your quota fast.
What to sort out before the trip
Two small things can stop you cold at the trainer. If you already have a breathing style equipped, buy Reset Breathing from the in-game shop for 100 Robux to free the slot. Hold onto your skill points too, because Flame techniques are purchased individually in the Skill Tree after the style itself is unlocked.
Wall Climb and Double Jump are useful additions. They are optional, but make scaling the cliffs and reaching the wooden house near Rengu much easier. Equip a katana and bring healing supplies, as enemies occupy the route.
How to reach Flame Trainer Rengu
In Forgotten Ruins, Flame Trainer Rengu stands atop a large wooden house. The building is close to the Rengu boss area, but reaching that landmark does not guarantee you have found the trainer. Travel there from Mistfall Harbour.
The Rengu boss occupies the ruins on the approach, and his cinematic attack can kill an underleveled character outright. If his health bar appears, break line of sight and keep moving toward the house instead of trading hits.
The six Flame Breathing training tasks
Complete the six objectives in sequence. Most are mini-games that require 100% progress. Use the task list on the screen’s left and the matching map waymarker to find each area.
1. Meditation
In this timing mini-game, a moving marker appears on screen; click when the timing is right. Follow the prompts repeatedly until progress reaches 100%.
2. Push ups
Follow the button prompt each time it appears and click it. Repeat until the task reaches 100%.
3. Boulder Split
For the boulder-cutting mini-game, shift the marker into the specified spot, then perform the movement displayed on screen until the progress bar is full.
4. Aim Training
Strike each target as it appears. This is the easiest mini-game; keep landing hits until progress reaches 100%.
5. Cup Training
A memory game. A black ball sits under one of three cups, which then shuffle, and you pick the cup hiding it. You need 10 successful rounds and have three lives, so a wrong guess costs one attempt. The shuffle speeds up as you go, so watch closely before the cups move.
6. Defeat the Flame Trainee Boss
The last task is a real battle against the Flame Trainee Boss, waiting atop the Forgotten Ruins area. Study its movements and dodge instead of attacking recklessly. Defeating it awards the style.
How to confirm the unlock and buy techniques
The quest’s completion and the base Flame Breathing style appearing on your character confirm the unlock. Before then, the Flame branch stays blank, and you cannot equip any Flame moves.
Unlocking the style is only the beginning. Spend skill points on individual techniques in the Skill Tree. Later moves require mastery, which increases when you fight with the style equipped.
| Technique | Unlock |
|---|---|
| Unknowing Fire | First skill tree node |
| Blazing Universe | Second skill tree node |
| Flame Undulation | Mastery 27 |
| Flame Tiger | Mastery 40 |
| Purgatory | Later tree requirement |
Buy Unknowing Fire first as your gap-closer, then grind toward Flame Tiger, which works as both close-range slashes when held and a forward flame projectile when tapped. Mastery climbs fastest on repeat Rengu boss runs in the same ruins.
Ignore the Wop City directions
Older walkthroughs direct players to Wop City, a location on the Ouwohana map reached through the map screen at Level 50 and above. It belongs to the original Project Slayers, where the Flame Trainer requires Level 75, 10,000 Wen, and 150 Demon Horns. Those directions and figures do not apply to the sequel, and following them wastes travel time. Requirements may change with updates, so use Rengu’s dialogue box to see what your character still lacks.
