Imo, ribbon spool is not very good. Half of your round you are only using 1 trinket, and it gets overshadowed by speedy shoes. Id rather have half the buff on every floor rather than a combined amount for half the game. Plus speedy shoes gives walk and run speed. Alarm is also kinda bad, if you're priming you should never need to use it and in most cases everyone gets to the elevator fine. You hella right about wrench tho, a free jumper cable every round is op, and you can always get a use out of it because it doesn't have a top capacity. Ribbon spool - D (only good for rnd) Alarm - D (can be useful, but throughout the floor you only have 1 active trinket) Wrench - A (good for newer players, works well in veemote runs for more experienced players. Overall win win)
imo wrench is just a worse veemote, especially for better players i do see your points on ribbon spool and alarm but they're niche and useful similar to the other things I put in b tier like night cap ^^ even though spool is basically just an alternate version of shoes it is still incredibly solid especially for distracting
