Wyvern is a mob added by Better Dungeons that can only be summoned by the incomplete item The Exterminator Prototype. There is no known way to get that item or summon this mob in survival.


This mob will fly around the target before it decides to collide with the target (like Ender Dragon), upon impact, the target will receive 2(HeartHeart) point of damage, using a bow is very recommended because of its flying speed.


  • It attacks everything except peaceful mob (animals).
  • If it doesn't have any valid target nearby it will stay still, until it finds a valid target.
  • It does not make any sound.
  • Even though it looks like a large mob, it's real size is only 2x2x2 blocks.
