Exclusive Treasure ○Try??

Hey everyone, I'm still pretty new and just hit level 10 with Batman. So, treasures got unlocked, and I tried my luck once, and got the exclusive 'Fire Bat' on the first try.. Is it normal for exclusive items to drop like this?? I thought it was rare, so this treasure is amazing. This treasure is currently at +9 enhancement and I'm still using it well. My friend also said they got it on their first try, so is it really normal for it to drop this easily? I'll keep this post short today. Your support is a huge help!!
