How to get achievement "Serious Contender"?

Question

Hello!

Searching some profiles on tibia.com saw someone got the achievement "Serious Contender"?

How is possible to get it?

Thanks in advance!

Answer 1

This Achievement is available for fully unlocking 100 cyclopedia medium difficulty monsters.

 Medium difficulty monsters... I think most often those that we have to kill in bestiary 1k. I'm not sure for 500 monsters, in my opinion 250-500 is 'easy difficulty' and 2500 is 'hard' :)

Answer 2

Achivement Serious Contender can be obtained after unlocking 100 monsters of medium difficulty in the bestiary. I would also like to add that it includes the rarest monsters such as Midnight Panter , Yeti , Crustacea Gigantica  etc.
