A main class boxer ability to give it some flexibility

Dirty boxing 

A multi rank passive that prevents the loss of sturm upon the first use of a non boxer skill/spell in a round.

Rank1 Utility skills
Rank2 Support skills
Rank3 Defensive skills
Rank4 Offensive skills
Rank5 All martial artist skills count as boxer skills and generate sturm.

That's quite op, they should not generate sturm

Perhaps I should have elaborated.

For the cost of main classing boxer, the first four ranks allow only the first skill used this round from another class to not break sturm, the fifth rank allowing the First martial artist skill this round to count as a boxer skill. You would not be able to Shukuchi into anything, so its  just meditate/cleanse and the various offensives, and only one of them this round.
