I have dedicated DAYS to unlock ONE skin...And, by the way, it lies to you.
Here's how it works...
You need Shadow Points to unlock Shadow Skins, unless you feel like forking over real-life cash.
It SAYS you can get 1,000 Shadow Points per fight, but that is a blatant lie, told twice. You only make a maximum of 500 per win in Shadow Survival. It says it in the top corner.
Here's what angers me even further...If you challenge a high level Shadow for 2,000 Shadow Points...You fight it twice, and it says in the top corner that you've earned 2,000...WHICH IS A LIE!!! You only get 1,000...WHICH, YOU CAN GET FROM 2 FIGHTS IN SHADOW SURVIVAL!!! Why does this happen, and why am I seemingly the first to bring it up?
