I Defeated Duke Fishron for the first time.

Immediately got the bubble gun (now I can defeat every boss (Mobile version 1.2.4.) with spectre armor. Its OP) Defeated him again, got the Flairon. Then again. Got the staff + the wings and again and then I got the book and then again and I got the tsunami. (Good thing I got all of this in order I didn't get anything twice :D)

Then I killed all bosses with ease: Got every boss trophy (except Duke Fishrons) and Ocram's trophy twice.

I read the news about Terraria 1.3.6 coming for PC and 1.3.1 coming for Xbox1/PS4/Switch. And I read about that is going great with Terraria update 1.3 for mobile.
