Evenicle 2:Items

Weapons
Similar to Evenicle 1, enemy drops are limited to what you currently have equipped. Your weapons and armor will not upgrade to the next item no matter how many +'s you get. You have to purchase and equip new weapons and armor to keep up to date. I will note that you don't really need to upgrade your weapons and armor on a regular basis, It's possible to keep outdated equipment for several chapters before upgrading.

For secondary stats, equipment that already has a secondary effect won't have another one overriding it if the equipment already has one. This also means that it cannot get randomized either so choosing a final weapon that doesn't have a preset secondary effect might be preferred for super late game grinding. Not that it should be necessary for clearing the game.

Japanese wikis have noted that the chance of treasure chests increase every battle that you don't get a drop and the chance persists if you save/reload until you actually get a chest. Keep this in mind for item grinding.
