Because the game does not provide clear defined names for different tiers of items and resources. The Wiki team decided on the nomenclature detailed in this page for them.
Equipment names depend on the Expertise that is needed to equip them. For better readability and compatibility with chats that do not support emoticons the actual image of the Expertise cannot be used.
|Tier 0||T0||/||Shop bought items that have no requirement to be equipped|
|Tier 1||T1||/||Items that require the Expertise to be used, also bought in shop, though auction sales are common as well|
|Tier 2||T2||C3||Items that require the Expertise to be used, exclusively bought in auction or crafted at blacksmith shops.|
|Tier 3||T3||C4 & C5||Items that require the Expertise to be used, exclusively bought in auction or crafted at blacksmith shops.|
|Tier 4||T4||C6||Items that require the Expertise to be used, exclusively bought in auction or crafted at blacksmith shops.|
|Tier 5||T5||?||Items that require the Expertise to be used. Presumably auction/blacksmith shop only. Not much data gathered yet.|
Alternatively they can also be called "Red Tier", "Green Tier",... equipment, but for purposes of consistency this wiki will adhere to the numbered tiers.
Item Tier T5 is not confirmed, as those items are not released yet.
|Rank 0||C0||Requires no Crafting (Skill)|
|Rank 1||C1||Requires Crafting (Skill) 1|
|Rank 2||C2||Requires Crafting (Skill) 2|
|Rank 3||C3||Requires Crafting (Skill) 3|
Each Rank has the possible addition "a", which indicates that this item cannot be found in quests. For example: Resources with the Rank
C0 resources that cannot be found in quests
While the disambiguation between different tiers of the skill Harvest and Alchemy (Skill) may seem unnecessary, since tier 3 potions use the tier 3 alchemy resources, the player levels to unlock these tiers differ. This is the reason for the differentiation between those two classification systems.
While the skill Harvest has more levels than the ones mentioned for classification in the following table, meaning it is more subdivided than needed for the different tiers of alchemy resources, finding the herbs is only unlocked at certain levels of Harvest, to be precise: Level 1, 2 and 7.
|Harvest Tier 1||H1||requires Harvest 1 to find|
|Harvest Tier 2||H2||requires Harvest 3 to find|
|Harvest Tier 3||H3||requires Harvest 7 to find|
|Harvest Tier 4||H4||requires Harvest 12 to find|
|Alchemist Tier 1||A1||Brewed with alchemy level 1|
|Alchemist Tier 2||A2||Brewed with alchemy level 2|
|Alchemist Tier 3||A3||Brewed with alchemy level 3|
|Alchemist Tier 4||A4||Brewed with alchemy level 4|
