Item Level

Patch 6.1 separated out the item level display.

Maximum achievable item level separated by patch, showing a predictable increase every even-numbered major patch, corresponding to the release of new Allagan Tomestones.

Item Level (IL or iLvl) of gear determines that gear's strength. Gear with a higher IL will essentially always be better than gear with a lower IL. This is especially significant at level caps, including former ones, since while gear could no longer increase in level, it could still grow in stats as reflected by its higher Item Level.

Player characters have an average item level that is the sum of the IL of all the equipped pieces of gear divided by the number of slots. Unless the player is equipped with a Shield, the main hand weapon's IL is counted twice in place of the empty off-hand. Thus, when trying to reach a required minimum item level for a duty, it can be best to upgrade the weapon first, even for tank or healer classes.

A notable caveat is with craftable gear. Only High Quality gear has appropriate stats for its Item Level. Any (NQ) Normal Quality gear has a 10% penalty in stats versus same-IL DAetherial, BGreen, or CBlue rarity gear. This is only a critical issue starting at level 50, once the stats on gear get larger than single digits. NPC vendors only ever sell (NQ) Normal Quality gear; the sole source of High Quality gear for Gil is from other players via the Market Board. Leveling gear can also be acquired High Quality from Side Quests, some of which award coffers.

Two pieces of gear with the same item level (assuming HQ items if applicable) equip-able by the same jobs provide the same increases in vitality and main attributes (i.e., strength, dexterity, intelligence, mind) but may differ in the number of materia melding slots and secondary attributes. The "stronger" item is therefore the one that maximizes the most desirable substats (usually Critical Hit) when fully melded.

Item Level vs. Class Level

From levels 1-49, there is a close to 1:1 conversion between the minimum level of the class when a piece of gear is equippable and the item level of the gear.

At level 50 and the current and other previous level caps (x0), there is a larger range of item levels due to higher item level gear being gradually released over the course of several major patches (~2 years worth of patches) when the relevant expansions were the current endgame.

In the "leveling" ranges of each expansion (x1-x9), item level usually increases by 30 before reaching level cap gear.

At a level cap, there are three "tiers" of item levels spanning 100 item levels (a consistent pattern since Stormblood).

• The first "tier" spans 40 item levels and is fully released with the x.05 patch of an expansion.
• The second tier spans 30 item levels and is released in the x.2 patch.
• The third tier spans 30 item levels and is released in the x.4 patch.

Each increase in maximum item level past the initial release of an expansion corresponds with the release of a new Allagan Tomestone and 8-player  raid tier.

Class Level Equippable	Max Item Level
50	130 (135 weapon)
60	270 (275* weapon)
70	400 (405 weapon)
80	530 (535 weapon)
90	660 (665 weapon)
100	730 (735 weapon)

* The Lv. 60 Coven Weapons are IL 280 but are no longer obtainable.

These maximum item levels are used on any former endgame content that lacks a more specific Item Level sync. For instance,  Snowcloak only syncs to level 50, so the effective maximum Item Level will be 130. Non-endgame content without specific Item Level syncs will have an effective IL sync corresponding to the max IL achievable by gear of the same class level as the duty.

Maximum item level is expected to increase to 760 (765 weapon) in patch 7.2 and then to 790 (795 weapon) in patch 7.4 until the next expansion (patch 8.0).
