2. Watch the video.
3. Orthos Gulo Gulo finished casting The Killing Paw at 0:26 (while under Lethargy).
4. The second part of that attack should have been cast in the same direction right after The Killing Paw, but it didn't.
5. A few seconds later, the second part of the attack (Savage Swipe) came without warning at 0:47 and one-shot me. This was after the mob had changed direction and auto-attacked several times.
6. I don't know if this is due to the Lethargy Protomander, since I used one at 0:05 during the first midcast of The Killing Paw, and it went on to properly resolve the second attack (Savage Swipe).

8. Someone else's perspective. Savage Swipe happened without Lethargy.
9. In this vod at 0:11 The Killing Paw resolved, the mob didn't do the second swipe, and chased down the character from across the room.
10. At 0:17 the second part of the attack, Savage Swipe, came out and killed him. It almost looks like the second attack can be queued as part of the mob's basic attack, and will kill someone as soon as they catch up with them.
