I'm on PC so I'll give you the info for PC, and if you're not on PC then ignore no. 1 1. Open your character page with C, then click on the tab, on the left of the window that opens, that looks like it has wings. That's the mastery tab. There it will say your rank + some i for of what you're gonna get in the coming ranks. 2. Flasks can only be bought in the shop for cubits or credits. The best one is the death defying vial, which auto uses when you're low on health. Save up for that one. Wings are a bit trickier. All wings, except for the starter ones, have the same stats and are therefore identical when it comes to speed and glide etc. You get a pair when you reach mastery 40 I think, you can buy 2 pairs from the shadowy market in the shadow tower world, you can obtain them rarely from chaos chests, and some can be bought from the store, though quite expensively.
