I see that there are Living Armor Training Bracelets so that you can train just the upgrades you wish. Would a variant where it stops the training of a specific upgrade be unfounded? I came across this seeing that people jump a fair amount while running. You level up strong legs, but not everyone wants to leap 10 blocks every time they jump, but it levels quickly if you do this type of running a lot.

I actively added some other upgrades to stop strong legs training so high cause it interfere's with jumping between EnderIO's travel anchors (especially if you use them like openblocks elevators) So an inhibitor would be great to have

There are already Bracelets for training specific upgrades whilst not allowing for training of others with it in use.

@mywither the request is to have both Blacklist and Whitelist options.

Having only the whitelist bands works, but it's tedious and would be quite nice to be able to just cap certain abilities so you can start and train any others, including those you have not yet gotten the first level of so you can't yet whitelist them.

I feel that this is part of what makes it balanced.

Training bracelets fulfill this fuction. Close.

Actually: Inhibitor bracelet that just completely negates all effects?
Then again, could just unequip the armor at that point.

In practice, for my last game I just "rinsed and repeated".: Trained the armor to its limit, stripped it and re-added the stuff I wanted, continued training, then did the same again until my desired upgrades had maxed out the armor.
