As you can see, next to the “wear removed” and “forge effect” the text is displayed as purple, indicating that the bonus from Wear and Tear is a defect, when infact it should be orange as it is infact a boon.
I thought those were always purple because it’s removing dmg on the machine. If it was adding health to the machine I’d think it wouldn’t be purple but as how I thought it worked was removing damage not adding health
If im not mistaken, according to this list there is both a boon and a defect called “Wear and Tear” One makes you do more repair, one makes you do less.
