Weak Legacy 2 Flame Breathing V2 Guide
Rengoku clan, Flame V1 mastery 200, Ablaze Spirits, Essence, yen, and demon player kills.
Flame Breathing V2 is the prestige upgrade for Slayers who started with the convenient Rengoku trainer in Starter Village and want a top-end PvE kit. Unlike clan-agnostic Water V2, Flame V2 hard-gates on the Rengoku / Renkogu clan, Flame V1 mastery 200, Ablaze Spirits, Crystal Essence, a large yen bank, level checks, and a short PvP kill requirement that must happen on a public server. This guide lists every common requirement, where to farm materials, and how to talk to the trainer without wasting a trip. Cross-check rankings on the Breathing Styles Tier List, clan odds on the Clans Tier List, style basics on Breathing Styles, free rewards on Codes, and raid loops on Raids and Quests.
Weak Legacy 2 (Roblox, Weak Games Corp.) rewards players who plan Flame as a lifelong main early. If you are still spinning clans, read the Rengoku section on the clans tier page before you sink weeks into Ablaze Spirits on the wrong lineage.
Who should chase Flame V2
Pick Flame V2 if you:
- Already train Flame V1 at the Starter Village Rengoku NPC.
- Own or can realistically spin Rengoku / Renkogu (Mythic band, about 0.5%).
- Prefer a village-adjacent trainer over mountain-only prestige lines.
- Want a style that frequently sits near S-tier in community PvE charts after the Flame V2 update.
Skip or delay Flame V2 if you are locked into Tsugikuni Moon, Kamado Sun, or a Water/Insect plan with no clan reset budget. Breathing reset potions cost Crystal Essence and yen—never reset Flame mastery until you can rebuy fees in one session.
Core requirements checklist
Community creator guides (including full Flame V2 walkthroughs) converge on this package. Always confirm the live NPC text after patches:
| Requirement | Typical target |
|---|---|
| Clan | Rengoku / Renkogu |
| Style mastery | Flame V1 mastery 200 |
| Ablaze Spirits | 10 |
| Crystal Essence | 2 |
| Yen | about 1,000,000 |
| Level | Meet the trainer’s level gate (high; confirm dialogue) |
| PvP | Kill 2 demon players on a public server |
| Trainer | Flame / Rengoku NPC in Starter Village |
Missing any single row usually blocks the V2 unlock even if the rest are perfect.
Step 1 — Lock Rengoku clan
Open the clan spin panel from the menu and chase Rengoku (UI may show Renkogu). Mythic odds around 0.5% are better than Tsugikuni’s 0.1%, but still rare. Redeem every working string on Codes before long spin sessions. Keep a strong Legendary only if you refuse to main Flame; otherwise Rengoku is the correct S-tier chase for this path. Full rarity tables live on the Clans Tier List.
Step 2 — Finish Flame V1 and hit mastery 200
Learn all available Flame V1 forms from the Starter Village trainer, then grind mastery:
- Quest packs along the Leveling Guide route
- Final Selection repeats while still human
- World bosses and early raids documented on Raids and Quests
- Hold G between fights so capacity never strands mid-combo
Mastery only counts when Flame skills land. Spam M1 without forms and the counter stalls. Capacity gourds from the village shop make long mastery sessions possible—buy them before cosmetics.
Step 3 — Farm 10 Ablaze Spirits (Mugen Train)
Ablaze Spirits come from Mugen Train content. Drop rates players report:
- Hard difficulty — roughly 100% spirit chance per clear (best farm)
- Medium difficulty — roughly ~40% chance
Farm Hard whenever your level and party allow. Medium is acceptable while undergeared, but expect longer sessions to hit 10 spirits. Bring potions, full breathing, and a haori with durability. If Mugen Train also drops Crystal Essence or spins on your patch, loot both in the same loop. Recheck Updates when event modifiers change Train rewards.
Step 4 — Bank 2 Crystal Essence and ~1M yen
Crystal Essence also drops from Little Village dungeons (often discussed around level 250+), some raids/events, and occasional codes. Flame V2 wants 2 Essence on top of whatever potions you already spent. Yen near 1,000,000 is a separate bank—quest turn-ins, boss clears, and weekend 2X drops help. Do not walk to the trainer with 900k and two spirits short; the dialogue will reject you and waste travel time.
Step 5 — Kill 2 demon players (public servers only)
Flame V2 includes a short PvP gate: defeat two demon-path players. Critical rules from community guides:
- Kills must register on a public server—private servers do not count.
- Targets must be Demon race players, not NPCs and not human Slayers.
- Fair fights in hubs or open fields work; griefing new players is unnecessary if you duel willing Demons.
Practice dash (Q), evasive dash while stunned, and block (F) from the Controls page before you hunt. If servers are quiet, hop public instances during peak hours rather than idling in a private lobby.
Step 6 — Talk to the Starter Village trainer
With clan, mastery, spirits, Essence, yen, level, and two demon kills complete, return to the Flame / Rengoku trainer in Starter Village. Confirm each checklist item in the prompt, pay the fee, and unlock Flame V2 forms. Learn the new kit in a safe biome, then take it into Mugen Train Hard and dungeon content for mastery and clear speed.
How Flame V2 plays
Flame V2 extends the aggressive mid-range fantasy of V1 with higher damage ceilings suited to boss burn phases. Compared with Moon V2’s mountain logistics, Flame keeps your trainer next to spawn—ideal for players who re-roll cosmetics and codes often. Compared with Water V2, you trade clan freedom for Rengoku synergy and Ablaze farming. Meta snapshots after the Flame V2 patch frequently place it beside Moon V2, Sun V2, Water V2, and Insect near the top of the Breathing Styles Tier List—verify after each balance pass.
Efficient weekly plan
- Monday codes check → spin toward Rengoku if still missing.
- Quest + Final Selection for yen and Flame mastery.
- Mugen Train Hard nights until 10 Ablaze Spirits and spare Essence.
- Dungeon Essence fill if Train RNG stalls.
- Public-server Demon duels for the two kills.
- Trainer unlock → form practice → boss routes.
Common mistakes
- Farming Ablaze Spirits before owning Rengoku clan.
- Attempting the PvP kills only inside private servers.
- Spending Crystal Essence on unrelated reset potions before banking the 2 required for V2.
- Ignoring Flame V1 mastery until the last day, then discovering the counter sits at 180.
- Comparing only thumbnail yen numbers without reading the live NPC list.
Flame V2 is a structured checklist, not a mystery. Secure the clan, master V1, clear Mugen Train Hard for spirits, stock Essence and yen, grab two public Demon kills, and the Starter Village trainer finishes the job. Keep Breathing Styles open for capacity rules and Raids and Quests open for Train and dungeon routes while you grind.
