A couple questions about hextech crafting
I'm still pretty new to the hextech crafting, as I wasn't playing league while it came out.
I see you can re-roll 3 skin shards to a permanent skin. Is this completely random, or does it take into account the prices of the shards? If I re-roll 3x 975rp skins, is it possible to get a 520rp skin, or would it be 975rp+?
Also what's the deal on the gemstones? I heard if you get 10 you unlock Hextech Annie. Is that their only use?
And one more, what's the most cost effective way to get blue essence? I've been buying random champ shards in the store for 1,700 IP and disenchanting them. Is there another way?
Thanks!
