I recently picked up 
a few days ago (and of course he is free this week, just my luck), and i've been really enjpying playing as him. But I'm not really sure what i should build with him. So far, I've got 
, and 
as key items, but after i get those two I have no idea on where to go from there. Any help would be greatly appreciated. Thanks :)

Essence Reaver is actually bad combined with Muramana, Mura gives plenty of mana regen to NOT need both while BT gives a shield helping you out more. Not a Jayce player but I do know brutalizer into cleaver is fairly core, as well as LW, BT, Mura most likely CDR boots (completely unsure here just off how I have played him in the past) and a defensive item (game dependent)
Infinity edge or bloodthirster is better on Jayce than essence reaver Infinity edge if you use your W frequently Bloodthirster if you don't really use your W, like you only use your W when you push towers. Before building items above get a brutalizer for early power spike, then build the brutealizer into youmuu's gjostblade.
