SMITE

"As He Bo kill three or more enemy gods with a single crushing wave."

Another painful "kill three gods with a skill shot" achievement (similar to Hou Yi, Chiron, etc.). You'll need a lot of patience and a lot of luck to get legit.

How to get: Crushing Wave is He Bo's ultimate ability, and you'll need to kill three gods in one cast. To get legit, your best bet is probably Arena, as all the enemy gods generally clump up in the same spots for the majority of the match, giving you the most opportunity to hit and kill three in one go. Good luck!

(Note: This achievement, like all other achievements is SMITE, must be done in PvP matches. Co-op matches vs AI do not count.)

EDIT October 13, 2016: According to Caboose McCloud and Element3579 in the comments below, it looks like you have to hit at least three gods with Crushing Wave, but you only need to kill one of the three you hit. This makes this achievement much, much more achievable (HOORAY!).

The strategy outlined above should still be the best method of achieving since once again, gods tend to form huge clumps in Arena, which gives you more opportunities to hit three gods in one cast.

EDIT November 6th, 2016: Fifapro reports that the hit three, kill one method described in the last edit does not work on PC. May be patched or may only be a Console/Xbox posi-bug. WIll edit the solution when more info comes in.

EDIT March 3rd, 2018: According to mereel1, a year and a half later on, and the hit three, kill one unlocking is still valid. At this point, I doubt it will be patched.
