Slot Upgrade Skill System

Every time you use a Bonus Crystal on your equipment, you gain experience in the Slot Upgrade Skill. Progressing this skill is the key to unlocking more powerful bonus tiers for your items.

Tier Progression:
Level 0-12: You can only roll statistics from the Tier 1 pool.
Level 13+: You unlock Tier 2, allowing you to obtain maximum statistics (e.g., up to 5.0% Leech or 7.0% Elemental Resistance).
Check your progress:
Type the !slot command in-game to display your current level and experience progress.

Equipment Upgrading (Bonus Crystals)

An item can have a maximum of 3 unique slots.
The system prevents duplicates - each slot on an item must provide a different type of bonus.

Reroll System (Rellor Crystal)

Item Function Description
Rellor Crystal
 Allows you to attempt to upgrade the value of an existing slot without changing its bonus type.

Success Rate: 30%.
Progression Logic: The crystal respects your Skill Level. If you are Level 12 or lower, a Reroll will never exceed the Tier 1 limit. Only upon reaching Level 13 can a Reroll "break through" into Tier 2 values.
