"Mr. Hyde" Cu Chulainn Solo

Item One: Obviously warrior boots is the usual way to go, but ninja boots have mana that goes with Cu's Passive. The attack speed is also very nice in Rafe Mode.
Item Two: This Item depends on who you are playing. Against any physical gods you want to go Gladiator's Shield. Against a character that is magical, who has heals, you want to go Pestilence. Against a magical character, without heals, I have been going Gengi's ever since they buffed it.
Item Three: This Item I base on the jungler and if the opposite solo lamer has heals or not. If the solo lane across from you has heals I would go pestilence. Against a physical jungles I would go Breastplate. Against a magical jungler and the solo doesn't have heals, I would go Urchin.
Item Four: I base this Item on how I am doing in lane. If I am losing I will go Urchin or Spirit Robe. If I have a lead I will go with a power Item that also gives mana or mp5 so it goes to my passive.
Last Item: I almost always go with a power Item lady that has added mana of mp5.
