The specialist card's skills, told by the file and not by arithmetic - #2322
Conversation
…by arithmetic Transforming changed nothing about the bar: the class skills stayed and the card's never arrived, which is the opposite of what a specialist is for. WHICH SKILL BELONGS TO WHICH CARD is Skill.dat, DATA section, second field - the card's "design", the same number the item exposes in INDEX[5]. The importer calls the column UpgradeType. The obvious rule is arithmetic, class == 31 + morph, and it holds for the historic cards: designs 1 to 29 really do sit on classes 32 to 60. Read against the file it is wrong on 283 of the 627 specialist skills, across 23 cards. It does not fail by leaving the bar empty, which would be noticed: for 18 of those cards the class it picks exists and belongs to somebody else, so it hands out another card's kit. Flame Druid, design 42: 31 + 42 = 73, and class 73 is another specialist's. Its own 22 skills sit on classes 70 and 71 with complementary cast ids 0 to 21 - so no single class holds a card either. While transformed only the card's skills are sent, and the two leading slots become the card's first skill instead of the class's basic attacks. Taking the card off puts the class list back. The bar builder is now one method: the class/specialist split has to be the same rule wherever the list is sent.
WalkthroughThe change adds specialist skill loading and unloading to ChangesSpecialist skill lifecycle
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR fixes specialist skill selection, but a transformed character may temporarily lose specialist skills when class skills are learned, and failed skill-list delivery could leave transformation state and the displayed skill list out of sync. The change is mergeable with explicit owner awareness and follow-up for these bounded consistency issues. Sequence Diagram(s)sequenceDiagram

Is there a way to avoid hardcoding this ?

also if there isn't we can have a better name with the name of the first specialist class instead

Renamed in 689b00a, and the number was wrong too.
Measured in Skill.dat on the Class column:
class 31 721 skills, 386 with no English name at all
class 32 11 skills, all named, first is "Pillow Fight" -> Pyjama
class 33 11 skills, "Two-Handed Sword Attack"
class 84 11 skills, "Frost Fist"
32..84 are the specialist cards, one per card; 31 is a bucket of monster and leftover skills. The specialist class is morph + 31, so the first card (Pyjama, morph 1) lands on 32.
It is now PyjamaSpecialistClass = 32. On avoiding it entirely: nothing in the files declares the boundary, so I would only be moving the number somewhere else — but this way the name is checkable against the data. Note > 31 was also inconsistent with the two other comparisons, which used >= 31 and so treated those 721 bucket skills as specialist ones; all three are >= 32 now.
Build clean, 980 tests green.
The constant is now named after the specialist it belongs to, and the three
comparisons agree.
Measured in Skill.dat, on the Class column (TYPE index 2):
class 31 721 skills, 386 of them with no English name at all
class 32 11 skills, all named, the first is "Pillow Fight" -> Pyjama
class 33 11 skills, "Two-Handed Sword Attack"
...
class 84 11 skills, "Frost Fist"
So 32..84 are the specialist cards, one per card, and 31 is a bucket of monster
and leftover skills. The specialist class is morph + 31, which puts the first
card - Pyjama, morph 1 - at 32.
`> 31` picked the right set for the wrong reason, and the two other comparisons
used `>= 31`, so `RemoveSpecialistSkills` and `SendSkillListAsync` treated those
721 bucket skills as specialist ones. All three are `>= 32` now.
Build clean, 980 tests green.

so none of the non specialist skill are after specialist one ?

Right, that partition is the whole assumption, so I measured it rather than argue it. Counting every record in Skill.dat by its Class column:
class 0 193 skills Rest, Pick Up, Open Shop the adventurer, and the universal actions
class 1 55 Upgrade, ... swordsman
class 2 53 Capture, Archery, Dagger Stab archer
class 3 49 Capture, Energy Bolt, Magic Shot mage
class 4 50 Standard Punch, Fists of Fury martial artist
class 27 33 Spiky Leather, Cower class 28 75 Poisoned Arrow, Vine Arrow | partner/pet families,
class 29 30 Flaming Armour, Spectral Plague | not cards and not player classes
class 30 72 Cake Strike, Spinning Spout /
class 31 721 386 of them with no English name at all -> a leftover bucket
class 32 11 Pillow Fight, Play Dead, Sleep ... > 53 classes, 627 skills, one CARD each
class 84 11 Frost Fist, Frost Rift /
So: nothing above 31 is anything other than a specialist card. 32..84 is 627 skills across 53 classes, ~11 apiece — the outliers are 39 (3), 40 (9), 47 (6), 57 (20) and 70 (8), still one card each.
And nothing a character owns can land there: what comes out of CharacterSkill is classes 0..4, the specialist ones are put in by LoadSpecialistSkillsAsync from the card's morph. The specialist class is morph + 31, which is why the first card — Pyjama, morph 1 — is 32.
The one thing the boundary does exclude besides player skills is 27..30, and those are correctly out: they are partner and pet skill families, not cards.

Wearing a specialist card gave its skills by arithmetic: a base vnum plus the morph, which happens to be right for the first twenty-nine cards and wrong afterwards.
Skill.datdeclares which skills belong to which card. The morph list has gaps - 30, 36, 37, 43, 44 and 50 are absent - so from the first gap onwards the two numberings drift apart and every card past it hands out another card's skills.The skills now come from the file's own declaration.
ISkillServicegained the lookup;TransformationServicecalls it on wear and clears on remove.How the drift was confirmed rather than assumed: for morphs 1..29 the arithmetic and the file agree, and each card's first skill matches its name - Pyjama/Pillow Fight, Ranger/Archery, Volcano/Magma Ball. Past the first gap they stop matching, and the mismatch is what a player sees: a card showing skills that belong to a different specialist.
Tested:
NosCore.GameObject.Tests450/450 (new cases for a card below the first gap and one above it),NosCore.PacketHandlers.Tests410/410, zero build warnings. Not played - I do not start the servers.Summary by CodeRabbit
