Enchanting is a way to make your weapon stronger. Push the limits and achieve power that can help you overwhelm your enemies.
There are three ways of enchanting your weapon:
1. Hyuuga Scrolls
You can get these scrolls from various in-game activities like sagas, missions, quests and completing Rifts or killing Raid monsters.
The chance of successful upgrade is pretty high, but gets lower with every level of enchantment. If you fail to upgarde, there is a chance that the enchantment level will drop by one. Also, there is a 5% chance that your weapon will be completely destroyed in the process. In summary:
5% chance to destory weapon on every upgarde attmept
there is a chance of degrading if you fail your upgarde
chance of success depends on current enchantment level
2. Ultra Enchant Scrolls
You can get these scrolls from some quests, rare rewards, events and cash shop.
They work excatly like Hyuuga Scrolls, but are slightly better:
no chance to destroy weapon - it's completely safe
higher chance of success than Hyuuga Scroll
3. Enchant Extractor
You can get this special item form rare in-game rewards and from the cash shop.
This box can extract most of upgrades from your weapon, but destroys it in the process.
Extracted upgrades come in a form of enchant scroll, which then you can use to instantly upgrade non-enchanted (+0) weapon to that level of upgarde. In summary:
extracts upgrades from weapon, but destroys it
you can use received scroll on a non-enchanted weapon to instantly upgrade it
