When a talisman is added to inventory (picked up, bought, traded), identical talismans automatically merge into one item — the remaining resource (mana / lifetime) is summed.
Why
No need to manually merge duplicates — inventory stays clean, and the resource is always stored on a single item.
~140 NPCs (essentially every raid and grand boss, plus a few special mobs) that take part in Soul Crystal level-up (the «Enhance Your Weapon» quest) carry a passive crystal icon — like a «Raid Boss» badge
Icon color
How the level-up is distributed within the party: red — to one member (the one who holds a matching crystal), blue — to a random party member, green — to everyone
When hovering over the icon
The resulting stage range this NPC raises the Soul Crystal to · the success chance · who in the party receives it
Why
You instantly see whether it's worth bringing a crystal of the needed stage — no cross-checking tables. The crystal must be in your inventory at the moment of the boss's death; one kill raises the stage by +1
