So you complete a level 34/35 arena match, you go down to the treasure room and you get a couple of strange coins and a mote of light because you haven't got a key, great !! I spent around 2 hours today completing level 34 and got absolutely nothing for it, I've heard ppl talking about trading tokens or whatever for a key but it's simple, when we finish 34/35 for the 1st time per week we should be given a key on completion, it's that simple. Small edit : I should say, this isn't a moan. I am enjoying the prison of elders, just some small changes I think need to be made.
