if you only wanna participate and not going full speed/engagement for winning then i wouldnt chip out imo...
also you have to chip out quite some...because when you hunt ,you gain hp again and you could fall then within into the next higher category...
but if you really insist on it..since entropiawiki is down (they have a marvellous skill calculator)...you can chip out things that contribute to hp like ...commando (if you unlocked it),courage,martial arts (i think)..
-->at jedegree site there is a option for chipping in/out health, there you see also the % contribution to hp...
