Notes about crafting materials.
- Every (stackable?) item can be used in any crafting discipline (and in mystic forge as well). Each item gets it's own flag for this.
- If an item is usable in crafting, the description says so and list all crafting disciplines that can use it and on which minimal crafting level. I believe it's automatically generated.
- The flag that determines it is different from the flag that tells to which bag an item should go. Not every item that goes to crafting bag can be used in crafting (various upgrade components) and not every thing usable in crafting goes to this bag as well (dyes and I think some food too)
Some "items" does not appear in inventory, but are treated similar to items anyway. These are marked with italics.
- Items that are consumed upon buying (influence bonuses, some recipes...)
- Recipes that are discovered
- Enviromental weapons (bundles)
- Items visible in your personal storyline
- And maybe Backpack as well.
Weapons are sorted by the type, it's useless to sort weapons to melee/ranged or martial/magical, because it all depends on profession - axe is a ranged weapon for ranger and melee weapon for warrior, while dagger is a martial weapon for thief and magical for elementalist). I loosely based on weapon article to sort them (types are alphabetically, and order is either hand -> offhand only -> two handed. All aquatic weapons are two handed, so no need to split these. Environmental weapons are a specific cause.
- Regular weapon (this needs a better name)
- Aquatic weapon
- Environmental weapon / Bundle
I prefer the word "bundle", since the game uses it. GW2DB & Guildhead lists "small bundle" (main hand) and "large bundle" (two handed). We can also split bundles for static/controllable (canons, siege machines, turrets...) and mobile (guns, stones, eggs etc)
The main sorting is by armor type (or class), but armor needs at least one more property - slot. I suggest splitting them by slot they come to because not all head armors are helmets, not all chest armors are coats, not all hands armors are gloves, not all legs armors are leggings, and not all feet armors are boots. Fortunately, all professionalism wear "Aquatic Helms", they are only "light", "medium" or "heavy". I sorted them in order they appear in hero window, from top to bottom with aquatic helmet as last, but we can sort them according to defence values - then it'd be: chest, legs, feet, gloves, head, shoulder, aquatic helm - with aquatic helm still as last, and head before shoulder, because head is more common than shoulder. All armor parts except for aquatic helms also have 1-3 dye channels or dye slots.
- Light armor (most names in parenthesis are from trading post)
- Medium armor
- Heavy armor
- Accessory (Trinket)
Back slot is arguable, but it still sits on the accessory section of the Hero screen and shares much more with accesorries than armor (no runes, and no division by heavy/medium/light). I sorted them in order of importance, but they can be sorted as they appear in-game in Hero screen as well.
- Gathering tool
These share a lot with consumables, they are similar to salvage kits, but it's hard to classify them as consumables, since they need to be worn in order to use them. Gathering tools can be split by quality too (copper, iron, steel, [...], masterwork, black lion)
- Town clothing (Costume)
Bags can be classified by # of slots as well). Backpack is a specific "item", as it can't be removed from it's slot.
- Equipment upgrade
- Crafting material
- Basic crafting material (these can be further split into "raw" materials, "refined" materials and maybe even "additional" materials for materials that are bought from crafting NPC (spools and lumps) but I don't know if that's needed. Materials are also tied to the crafting disciplines and levels as well as tied to "tiers" 1-6, so they can be split based on that. Gemstones, Jewels and Doubloons are also an upgrade components.
- Fine crafting material
- Rare crafting material
- Gemstone and Jewel
- Crafting component I'm not 100% sure about this, as I only done leatherworking, so I don't know much about cooking or jeweler intermediate products (if any).
- Mystic item
- Crafting material
- Consumable - these items disappear after double clicking on them. Are "consumed". Various consumables (nourishment, alcohols, manuals, recipes) are tied to character level, while recipes and nourishment are also tied to professions and professions levels, as well as tiers 1-6
- Package (or Container) - TP list them separate from consumables, and that may be quite accurate, because some other item is given in return, you don't "lose" anything by consuming them
- Salvage Kit (they are quite "unique" consumables, as they have "uses" that works similar to stacks, but not quite - can't be split and merged. Kinda similar to gathering tools, but they work by simple double clicking on them, unlike gathering tools which needs to be equipped
- Manual (or Trait Guide)
- Tonic and Hylek Potion ("Festive")
- Skin (PvP, HoM and Halloween weapon/armor skins for example )
- Transmutation Stone
- Items that grant bundle upon using
- Various other consumable items that aren't tied to any category - like Tome of Influence, Chalice of Glory, Black Lion Key, Instant Repair Canister, Revive Orb, Evon Gnashblade's Box o' Fun, Cow Finisher or letters
- Gizmo - similar to consumable but are NOT used up after use. Might be time limited (Golem Banker)
- Dungeon tokens
- Other tokens (Badge of Honor for example)
- Salvage item
- Event item
- Items used to complete Hearts - similar to "event items" but without the tag
