Interesting build and runes. I do like to point out that your forgot to fill in the last level at the skill order and that you did not recommend your readers to take the 3rd R level at 16. Since your item set specifically says 'purchase order' I experience a lot of benefits from an early glory after cleaver rather than building it last with your boots.

I would also like your thoughts around the choice of resolve tree. Like, do you know if revitalize works on yourself (since it says 'targets')? And why would you go for a resolve tree as a secondary while Darius, in my experience, relies on early domination. I personally would go for another keystone as well. I think that harvest is best on farm junglers since you only get if form large minions and it if mid-late focused while Darius is an early powerhouse.

Would love to hear your thoughts!
