@faflec, I'm generally in favour of your plan but uncomfortable with specifically calling to inflict Severe Consequences - that's saying we're ambushing people and breaking their legs or equivalent, which
may be
technically tournament legal but certainly isn't in the spirit of international cooperation - maybe limit it to draining their Chakra, drugging them, maybe Moderate Consequences (as they're a fair bit less terrible and heal much faster)?
E: Moderate Consequences still take a week to heal, which is enough to screw them in the next event without taking them out of commission for a whole month+.
