abnormal status resistance & elemental resistance cap?

Should be immune to everything except Chaos Pink Bean, Root Abyss, and a few other bosses.

why not immune to those bosses? special property that ignore our resist?

It's 5/10% for the first CK then 2/5% for additional CK which is 10+5*4=30%. (10+5*2=20% currently available in KMS)

With 100% status resist, you are immune to all status ailments like sed, seal, pig, etc.

ah neat
