I had the oddest encounter...

One week ago, me and my friend Where playing in at the Mystic Castle When all monster disappeared we jumped around our spot and saw nothing. So we moved on and fought on our way back, we jump to a corner to rest my stamina. You’ll never guess what we saw a huge group of bat stuck in each other there were about 30 I killed them all and with double exp got 2 level 85.

p.s. I know seeing stacked monster is common but seeing 30 in a single stack

p.p.s I don't know how 2 take screen shot or I would have
