Items often aren't the item level that GetItemInfo claims. This is because of:
- Upgraded items
- Legion Artifacts
- Timewalking scaling
- Overall post-7.3.5 world reward scaling
But sometimes you still want to know what level they are. This is easy enough with tooltip scanning, but has certain pitfalls it's easy to miss. So, this library does that for you.
Example of use:
LIL = LibStub("LibItemLevel-1.0")
-- ilvl of the item in slot 6 of the backpack:
print(LIL.GetItemLevel(0, 6))
-- ilvl of an item by id
print(LIL.GetItemLevel(12345))
-- ilvl of an item in an inventory slot
print(LIL.GetItemLevel("HeadSlot"))
-- ilvl of an item by item link
print(LIL.GetItemLevel("item:12345"))
