You can't miss, so you benefit from the heavy War Scythe damage with no drawback. And look at that range!
It's also excellent with Sunray's blind effect for two surprise attacks! Once when they are two spaces away and again when they are adjacent.
I found it as +2, used a stone, and got Projecting. I feel lucky. I'm actually a Wand of Living Earth build because I wanted to try all the ally buffs, but this War Scythe let's me safely do some serious melee damage.
And it's even better when my Golem is distracting an enemy. I can blind the enemy from 2 tiles away and get up to 6 surprise attacks. This is truly an excellent combination on a Paladin.
That's the max range. You get +1 from Projecting, and +300% from Smite. So a range of 5.
