Happy Wars

This achievement is for adding buffs to items.

To get to this part of the game, go to the "Character" tab at the top and then go to "Item Remodeling." From here you can add a buff, store a buff, or remove a buff. While the description indicates that this only counts for adding a buff, I have found that storing a buff and removing a buff also counts towards this achievement, with one caveat - when storing or removing a buff it doesn't add to your achievement progress bar, and only "locks in" the progress you made storing or removing buffs once you actually add a buff to an item.

Storing buffs is much faster and much more useful than adding buffs to 100 random items that you may or may not need, so I highly recommend going that route. Once you find an item you want to use, you can add one of those stored buffs, and the achievement progress meter will finally update, reflecting all the buffs you stored. Removing the negative buffs to items is also a useful.

Example: If you start at 0% progress and then you store 10 buffs, then after that add 1 of your stored buffs, you achievement progress will jump to 11%. It will still show 0% until you actually add the buff.

When adding buffs, you are prohibited from adding a copy of an identical buff, but different levels of buffs (i.e. Attack up lvl. 3 and Attack up lvl 2) will stack on the same item.
