SOL's damage/aoe is too damn high.

Defensive items, especially Warmogs (Belt/Belt), Dragon Tooth (cloak/cloak), and Zephyr (belt/cloak). Blitz is another good one - if you cant reach him, yoink him to you. Assassins are good too, if they can reach him. Especially Pyke. SoS on Pyke means you start pretty much permastunning everything.
