Until Level 29 (Danburite Earrings), there are only 2 other sets of earrings that can be found in-game that give +Intelligence stat. Those earrings are: Cactaur Earrings (No longer obtainable, Item Level 11, Level 1 equip) and Plundered Earrings (EXTREMELY LOW DROP RATE) which are obtainable in 'The Hole' in Sastasha (Item Level 17, Level 15 equip).

Should they not have craftable earrings for Level 9 and 19 for Intelligence and Mind like they have STR and DEX ones?
