The best synergy you will ever find
+ 
Just played in a game, I main devourer jungle kayle so just went jungle as usual and this mid lulu and i just somehow followed eachother around the entire game practically, and destroyed wherever we went. With all the synergy we had, it took the entire enemy team to kill us both, and by that time they had used to much crap that they didnt have anything left to deal with the rest of our team.
Now for the synergy explanation...
put W on
put W on
Double Speed!
puts E on
heals
with W
Kayle's crazy attack speed procs lulu passive like crazy
Both shields and heals combine to make sure nobody dies
When low...
ults
ults
When the
adc is low, simply turn him into MEGAKOG THE DESTRUCTOR by putting all buffs on him
I don't really think I was able to capture the true synergy potential of kayle and lulu, but if one of the 4 jungle kayle mains out there reading this post ever encounters a lulu, be their best friend and stick by their side. Nothing can go wrong.
