Sunstrike.. Maybe more...
 

Did a duel, Sunstrike hit for 1082 x2 when only supposed to hit once?
Might want to look into this....

I believe there is a bug currently out there (since last patch?) that is duplicating the killing blow. It's a display issue as it is not actually doing twice th damage or two hits it just appears that way.

It actually did dbl damage not just the message, so broke....
Twincast ? =P

the more i see of vyal, the more i start to sympathize with lord bob

if it really did 'dbl damage' cut and paste your log

Telling you what happen no need to troll a bug forum.

was the sunstrike a killing blow?

It was on the second, I was over 1048 HP buffed and at 100% Life when it was casted.
Died on the second cast / caster only showed one cast.

Well over 1048 btw.

The double damage killing blow bug shows in logs.

no shit

doesnt sunstike do 1600+?

Good test actually. If it's actually doing double damage and not just reporting wrong that would be a pretty big bug (and explain why my charmed rogue pets seem be getting a killing blow with backstabs more often than normal).
