Let's say I, level 50 Paladin, try some 20-level dungeon. I have a 50-lvl sword and a 30-lvl sword. Would wielding a 30-lvl sword make any difference compared to 50-lvl sword, since it's a 20-lvl dungeon anyway? Same goes for armor, of course, and stats they give to character.
Both swords will IL sync to the max item level available at character level 20-something and materia will be ignored. The only difference will be in which secondary stats are present. If you had a third sword that was the maximum IL available at the dungeon's sync level, you could equip that sword and it would not IL sync, and its materia would be active.
