good strategy for case gambling

if you get your dodge as high as possible you can attack for basically free.

it still uses ammo and I think the gun still gets worn down but the other equipment is fine and you don't lose heart for that attack.

if you get your dodge high enough, by upgrading the skill and wearing high quality boots then you can sometimes even get 5 free attacks in a row.

then just get to about 70% case chance on each battle and your pretty much guaranteed to get alot of cases. Use food as well since it's worth it.
