Like, you can consume one to reroll a lockpicking check. That bit makes sense.
But also sometimes you’ll pick a lock, not reroll, and it’ll consume one of your tools anyway.
Same thing with trap disarming kits.
Do they have a ‘durability %’ that is just hidden to the player? Does it relate to the difficulty of the lock itself?
Sometimes I’ll pick seven doors without a single one being consumed, and sometimes three of them will be consumed in a row… ?
I don’t get it, and I found no explanation for it anywhere in the game.
Are you sure it’s actually consuming the tools when you get the message that they were used? I noticed the same message and had the same concern but when I started paying closer attention to the number of tools I had in my inventory it only ever went down if I failed a lockpick. If I lockpick and succeed I get the message, and sure I did use my tools, but they remain in my inventory.
