asking about xir, lix, upgrade stones

[yuda_gon]

Hi guys,

can someone tell me the difference between normal upgrade stones (lix, xir, urlue i think) and the bless ones, lucky, and the ones that have xir[2] or [3] on the sides. I've been wondering about these.

And also as you see the window when upgrade weapons, sheilds etc there is the circle (where you put the stones) and there are 3 places on the buttom. What are these for? To put stones to improve the rate of upgrades?

Thanks in advance for the help

Elrue- For weapon upgrading 0-3+
Lix-For weapon upgrading 4-6+
Xir-For weapon upgrading 7-9+

And Depending on their tier they work with certain weapons. [Ex: Elrue[1] can work on weapons with item level 1 requirements. Elrue[2] and work with items with item level 2 requirements. So on and so on.]
Lucky Elrue/Lix/Xir have a chance of double upgrading an item.
Blessed Elrue/Lix/Xir have a less chance of breaking an item.
Normal are just normal xD.

Also the three slots at the bottom are for Fiesta Store miles which protect against breakage and downgrading on varying amounts depending on the type you buy.
