Why Are Some Codes Not Working?
There are a few common reasons why a code might not redeem:
- You’re on an old server – rejoin to refresh.
- The code has expired – most codes have short lifespans.
- It was a one-time code already redeemed.
- Typos or case sensitivity errors – codes must be exact!
Tips for Using Your Kengun Online Rewards
Once you redeem your codes, you’ll get a bundle of rerolls or spins. Here’s how to make the most of them:
1. Use Spins Wisely
If you’re aiming for a top-tier clan like Kure, Niko, or Raian, save your spins until all potential clans are in rotation. Don’t burn them all on basic rerolls.
2. Stat Reset Timing
Use stat resets only after you’ve experimented with a few fighting styles. Some builds work better with specific stat spreads, so don’t rush into resets until you’re ready.
3. Trait Strategy
Traits like “Fast Learner” or “Iron Body” can seriously change your training or combat efficiency. If you land a good one, keep it!
4. Switch to Empty Servers
Codes sometimes glitch on older or full servers. Use the Roblox extension RoPro or similar tools to find a new server for better redemption rates.
