1. It works on weapons and armours, but not jewelery. So u can upgrade your helmet, chest, shoes, though i dont think u'll see it glow like the weapons does.

2. Bless increase your chance of success rate (or degree the failure rate.. but it doesnt mean the item wont break), and lucky gives u the chance to enhance +2 in 1 go... (so u can go straight from +1 to +3...)

3. Yes, for to get to +1, +2, +3, you need elrues, and if you're item is already +3, and u're going for +4, +5, +6, u need lix. And to get to +7, +8, +9 u need Xir.

And note that Level 1-28 items use level 1 stones (with the little 1 on top left corner), and items lvl 30-49? or 59? requires lvl 2 stones. You can check wat level stone you need, by looking at the description of your weapon/armour, it'll tell u whether it's level 1 or 2
