What’s Gem?
Gem is for equipment to upgrade its stats. Mainly there are three functions about the gem: Gem Acquisition (Seek Treasure), Gem Embedment, Gem Upgrade.
How to Acquire Gem
1. Gem is available when the main city reaches Lv.30. Players can view it by opening Ninja –Equipment –Gem.
2. Click on Gem tab and players can seek treasure that includes Blue, Purple, Red and Gold Treasures.
3. Blue Treasure is where you start seeking treasure. Seeking Blue Treasure may give you a chance to unlock Purple Treasure that may unlock Red Treasure which in turn may unlock Golden Treasure.
4. Blue Treasure (2000 Ryo) Rewards: Broken Gem, Blue HP Gem, Blue ATK Gem, Blue CH Gem
Purple Treasure (5000 Ryo) Rewards: All Blue Treasure rewards, Purple HP Gem, Purple ATK Gem, Purple CH Gem
Red Treasure (20000 Ryo) Rewards: All Purple Treasure rewards, Red HP Gem, Red ATK Gem, Red CH Gem
Golden Treasure (50000 Ryo) Rewards: All Red Treasure rewards, Golden HP Gem, Golden ATK Gem, Golden CH Gem
5. Players can spend 40 Gold directly seeking Red Treasure, which may give you a higher chance to get Red Gem.
6. Players can use Ryo to seek treasure 10 times every day. VIP extra seeking times will be added after the weekly Beta test. (For example, VIP1 can give you 125 seeking times and VIP3 175 times, etc.)
7. Players can check out the gems you take in the bag and sell them.
8. Players canalso use Seek All (automatically seek treasure 10 times) and Sell All (Automatically sell all broken gems in the bag) for free!
How to Embed
Choose any gem to embed on the equipment to raise its stats
Note: Clicking to embed or remove gems is free of charge!
How to Upgrade Gem
1. There are 10 levels for each gem from Lv.0-Lv.9
2. How to Upgrade: Devour EXP of all unlocked gems in gem slots to upgrade and boost the stats.
3. You don’t have to worry about losing EXP when you devour gems. GemEXP can accumulate and inherit. For example, Gem B devours Gem A and Gem C devours Gem B. Then Gem C gets EXP of Gem A and B.
4. Players can lock gems in Gem Slot to avoid the gem being devoured.
5. Broken gems can’t upgrade or embed, but you can click to vanish it and get Ryo.
6. Note: Remember to lock the gem removed in case the valuable gem is devoured when devouring gems.
