When Tekagen halves your STR in battle, it seems to proportionately reduce your carry limit, leading to being overburdened if you're anywhere near your actual carrying capacity and losing out on M if you try to activate Tekagen. Hasn't been thoroughly tested, but in line with that line of thought I was able to act normally by severely reducing the amount of stuff I'm carrying.

This isn't a bug I think, Tekagen halves your strength, and thusly all the benefits it brings.

It's meant to be a representation of the character holding back, according to its description. Lowering their stats is just a mechanical expression of that but it almost certainly isn't meant to make you actually weaker.

If anything, this needs to be moved to Balance Fu.
