Yes raditz is right, all defences there are utterly crap except namek rare defence with 860 base defence
here's a picture of a jacket with physical defence.
Anyway i'll make a list of very usefull stuff from the gambling machine.
~Level 60 scouters (ex/rare/) Legend is epic due the 8 slots and not binding.
~all rare ear-rings (either due their effect, if not can always be boxed into 19 CD or 9 attribute bonus)
~all rare necklaces (either due their effect, if not can always be boxed into succes rate, anti bleed or w.e u want)
~~Excelent ring that gives you stun and fear reduction
~~Excelent ear-ring that gives you stun and bleed reduction
~1100 LP , 10 RP scouter chips
these are the major ones.
However there are loads and loads of different kinds of item effect rings and ear-rings, up to you if u need it in certain situations or not.
