There may be good loot up in crystal, but be prepared for harsh attacks on you, especially if your defenses aren't that well upgraded
I've got all black walls with a couple at level 9, most are maxed defenses and 4 attackers over the night stole 500-600k gold altogether (2 wins and 2 loss defenses), while I had 6.5 million gold saved up for my level 3 xbow)
And I was only at 1800 haha!
So be prepared
