I want to unlock lvl 7 mastery on nid but don't have enough essence but it says I can unlock it with one "nidalee permanent"
Does that mean I will get lvl 7 mastery but I will lose nidalee and have to buy her again? And do I still keep my skins?
no. it means if you have a champion shard for nidalee, you can use that to unlock the mastery instead of blue essence.
you can get more blue essence by buying mystery tokens with ip btw.
A "Champion Permanent" is a Hextech crafting component (which is pretty poorly named to be honest) which is obtained when you reroll three champion shards, and randomly get a champion you already own.
Why do you have to use anything to unlock the next level mastery?
I mean .... shouldn't we be able to get the next level mastery w/o unlocking chests?
Me personally I just save the keys and the chests and do not wish to unlock any of them. So I cannot get essences and I cannot get any of the other requirements so I just sit with 2 tokens and cannot do anything w/o spending IP on a RANDOM chance at the needed thing for 1900 plus LP which takes time to farm ...
There are just so many other ways they make money forcing RP use to achieve and get things in this game why does EVERYTHING have to be this way?
