Grinding EXP in Rohan Online is a long road — but a Growth Seal can cut that pain significantly. Here's how to upgrade your Growth Seals through the Recycle System and aim for the best possible outcome.
What Is a Growth Seal?
Growth Seals temporarily boost your EXP gain. They come in two durations (7 Day and 15 Day) and three boost tiers:
- 100% — doubles your EXP gain
- 200% — triples your EXP gain
- 400% — quintuples your EXP gain
⚠️ All recycled Growth Seals are untradeable. You can't sell these, but you can use them yourself.
7-Day Growth Seal Recipes
Basic Recipe (No Extra Material)
Growth Seal (7D, 100%) + Growth Seal (7D, 100%)
= Growth Seal (7D, 100%) OR (7D, 200%) OR (3D, 400%)
Three possible outcomes — pure RNG.
With Rare Preservation Stone (Better Odds)
Growth Seal (7D, 100%) + Growth Seal (7D, 100%) + Rare Preservation Stone
= Growth Seal (7D, 200%) OR (3D, 400%) OR (7D, 400%)
Adding a Rare Preservation Stone removes the lowest-tier outcome, improving your minimum result. The 100% result is gone — you're guaranteed at least 200%.
15-Day Growth Seal Recipes
Basic Recipe
Growth Seal (15D, 100%) + Growth Seal (15D, 100%)
= Growth Seal (15D, 100%) OR (15D, 200%) OR (7D, 400%)
With Rare Preservation Stone
Growth Seal (15D, 100%) + Growth Seal (15D, 100%) + Rare Preservation Stone
= Growth Seal (15D, 200%) OR (7D, 400%) OR (15D, 400%)
Again, the Preservation Stone eliminates the weakest outcome and opens up the top-tier result.
Should You Use a Rare Preservation Stone?
Yes, if you care about the result. Without it, you risk landing on 100% — the same tier you started with. With it, your floor jumps to 200% and the 400% result becomes achievable.
The Rare Preservation Stone is available from the Item Mall and also as a tradeable item from other players, so you can source it from the market.
Quick Tips
- The Recycle System never fails — you always get one of the listed outcomes.
- Growth Seals are untradeable regardless of recipe — these are for personal use only.
- If you're farming EXP seriously, aim for 15D 400% — the longest, strongest option in the game.
- Save your Rare Preservation Stones for Growth Seal recipes where they matter most.
- Place the Preservation Stone in the Stone Slot in Recycle 2 — not as a regular item input.
- ⚠️ Novice Preservation Stones do NOT work in these recipes. Rare or Unique only.
FAQ
Q: Can I combine a 7D and a 15D Growth Seal together?
No — recipes require two seals of the same duration tier.
Q: Why did I get a 3D 400% instead of 7D 400%?
That's RNG. The 3D 400% is a valid outcome in the basic 7D recipe. Using a Rare Preservation Stone removes it from the pool.
Q: Are these worth recycling?
Absolutely — especially if you have extra 100% seals sitting around. Even without a Preservation Stone, you have a chance at 400% which is a massive upgrade.
