Attention: You must have a Wyvern for this exploit
Happend on retail: If you wanna se if Antaras is allive you only have to take your Wyvern and fly to the spot over the Antharas Nest who he is spawning. Now you can /target Antharas and if he is allive it will show you his HP-Bar or not if he is not allive at the time.
Edit: Easiest way to get a wyvern --> Be a Clanleader and go for a castle
