德丝缇拉克 is one of many rare spiders introduced in patch 4.2 along with many other challenge tames. He has a unique lavender/neon blue skin. Unfortunately, players cannot simply tame him since he is immune to taming until he drops below 20% health. As of Battle for Azeroth, Deth'tilac has been scaled up to level 120, so killing him prematurely is no longer an issue. However, his ability 必死一击 is still a huge issue. If he casts this on you, it will instantly kill you. It cannot be dodged, blocked or parried.
*As a special note, Deth'tilac is one of the few pets that have a unique attack speed. Most pets have attack speeds and deal damage that balance out (despite having varying speeds and damage), however, Deth'tilac's attack speed is so fast, that at certain Haste levels it can be a DPS loss due to hitting an attack speed floor. I do not recommend actually using him for PvE or PvP content.

How to Tame:
- After engaging in combat, send in your current pet as a sacrifice. Dethtilac will use 必死一击 which will kill it. Doing so will cost him 10% of his health for every cast. Be careful to avoid stealing aggro from your pet.
- Use 焦油陷阱 and 震荡射击 to continually slow him, while resurrecting your pet after every cast of 必死一击.
- After he is reduced to below 20% health, tame him!
