If you're just sniping the two newties on the middle platform, you have plenty of range that you don't need Eagle, and Blizzard gives your Strafe a chance for OHKO (11.5% per shot).

But do the instant kill effects stack like that though? Since Strafe usually counts as one hit ( not an insta death with damage reflect. KB's once instead of 4 times ), wouldn't the insta kill be just 3% per strafe? Just a wild guess.
