[quote name='jalu6']Two more questions: is it worth saving the gems I'm finding along the way? Do they get combined later on like in RE4? Or should I just sell them?
Also, the body armor that's for sale? Does that cut down on the damage you take permanently, or just until it runs out? Is it worth the investment?[/quote]
You can go ahead and sell those treasures. There is no combining of treasures in RE5 and you don't need to have all of them at once for the Treasue Hunter trophy. You just need to have had each of them once.
As for the body armor, it's helpful in all modes but Professional (to an extent). It can make noticeable differances. In Pro, almost every hit will put you into Dying state, however, the correct armor can sometimes leave you with a sliver of health, so you can heal yourself. It's random though and not too reliable. I say it's worth the slot.
