Summary

UpgradePacketType.CellonItem was already defined and UpgradePacket already carried CellonInventoryType / CellonSlot, but no operation claimed the kind — so up_gr with type 3 silently did nothing. This adds CellonOperation.

Cellons add a permanent stat option to jewelry rather than raising an upgrade level:

  • the cellon carries its tier in Item.EffectValue
  • the jewel caps how many options it holds (Item.MaxCellon) and how strong they may be (Item.MaxCellonLvl)
  • success odds fall as the jewel fills (85% empty → 30% at five options)
  • the cellon is consumed either way
  • a jewel already holding every option its tier offers fails outright, rather than reporting a success that adds nothing

Rolled options are persisted through IDao<EquipmentOptionDto, Guid>.

Also adds a protected Roll(int) helper on UpgradeOperation for operations needing more than the skeleton's single success check — cellon rolls an option type and a value on top of the outcome.

Not in scope

The options are stored but not yet applied to a character's stats. EquipmentStats already carries Hp/Mp fields that nothing consumes, and EquipmentStatsService.CollectBCards documents that a worn piece has no route to its options. Wiring that up means loading options alongside the inventory rather than querying per stat resolve, so it is left as a follow-up.

No schema change: the EquipmentOption table and its FK already exist.

Test plan

CellonOperationTests — 5 cases covering success, failure, a cellon above the jewel tier, a full jewel, and exhausted option types. Full UpgradeService suite green (33 passed).

Summary by CodeRabbit

  • New Features

    • Added Cellon upgrades for jewelry, allowing players to permanently apply a randomly selected stat option.
    • Cellon attempts now validate tier compatibility and available jewel capacity.
    • Successful upgrades charge gold and add the selected option to the jewelry.
  • Bug Fixes

    • Cellon tier information and jewelry capacity are now read correctly from item data.
    • Failed or invalid attempts consume the Cellon without modifying the jewelry.

Cellons add a permanent stat option to jewelry instead of raising an
upgrade level. UpgradePacketType.CellonItem was already defined and the
packet already carried the cellon slot, but no operation claimed the kind
so up_gr with type 3 did nothing.

The cellon carries its tier in Item.EffectValue; the jewel caps how many
options it holds (Item.MaxCellon) and how strong they may be
(Item.MaxCellonLvl). Success odds fall as the jewel fills, and the cellon
is consumed either way. A jewel already holding every option its tier
offers fails outright rather than reporting a success that adds nothing.

Rolled options are persisted through IDao<EquipmentOptionDto, Guid>. They
are not yet applied to a character's stats: EquipmentStats.Hp/Mp exist but
nothing consumes them, so that wiring stays a follow-up.

Adds a protected Roll helper on UpgradeOperation for operations that need
more than the skeleton's single success check.

ImportEffectValue maps DATA by ItemType and had no case for
ItemType.Upgrade, so cellons (vnum 1017-1026) parsed with EffectValue 0.
CellonOperation reads that value as the option tier and rejects anything
at or below zero, so no cellon could ever be applied.

Item.dat carries the tier in the third DATA value, matching vnum - 1016
across all ten cellons. Every other upgrade material has an all-zero DATA
row, so reading it there leaves them at 0 as before.

Review Change Stack

Walkthrough

Adds cellon parsing and a CellonOperation that validates jewelry and cellon tiers, rolls unused options, persists successful options, consumes cellons, and charges gold. Tests cover success, failure, rejection, capacity, and parsing cases.

Changes

Cellon upgrade flow

Layer / File(s) Summary
Cellon and jewel parsing
src/NosCore.Parser/Parsers/ItemParser.cs, test/NosCore.Parser.Tests/ItemParserTests.cs
Upgrade items now read their effect value from DATA. Tests verify cellon tiers, other upgrade materials, and jewel capacity values.
Cellon option application
src/NosCore.GameObject/Services/UpgradeService/CellonOperation.cs, src/NosCore.GameObject/Services/UpgradeService/UpgradeOperation.cs
CellonOperation validates tiers and capacity, selects unused options, rolls values, persists successful options, consumes the cellon, and refreshes both inventory slots.
Cellon operation validation
test/NosCore.GameObject.Tests/Services/UpgradeService/CellonOperationTests.cs
Tests verify successful and failed rolls, invalid tiers, full jewels, exhausted option types, persistence, gold, inventory consumption, jewel state, and response packets.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to d1979

The new jewelry upgrade path can treat certain non-cellon inventory items as valid cellons and create permanent option records, while concurrent or partially failed requests may leave item, currency, and jewelry state inconsistent. Merge should wait for canonical cellon validation and explicit state-consistency guarantees, or documented owner acceptance.

Validate that the selected material is a Cellon.

Line 84 uses only EffectValue to identify a Cellon. A client can select another owned item with an accepted effect value and use it to persist a permanent jewelry option. Require the canonical Cellon item identity before reading its tier.
