Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
HI. How ya doing? Goooood. Anyways. This guide is for Sion and his awesome Enrage and tanking aspects. With his abilities its very easy to do so. Enrage + Warmogs is fantastic, equally out at 6.6 hp per kill.
There are 2 main items I go for. Rod of Ages and Warmog's. Rod of Ages gives you enough mana and AP to last you the whole game. Warmog's + Enrage, well, I've gone over it before. I LOVE IT. Its so much HP mid and late game.
Rod of Ages- I start every game, usually with this, it gives you the Hp, Mana and AP boost you will need for your game. Starting early with Ruby Crystal and Enrage gives you a good start. If you don't like it, try a Sapphire with HP pots for more sturdy survivability. Focus on them last kills, you can usually finish this fairly quickly if you skip boots.
Boots of Swiftness - I have experimented with other boots, but the speed chase + Quintessences are just so yummy. Offsets, I'd go Mobility to go to creep groups to creep groups.
Warmog's Armor - The cream and crop and my favorite item in this game. Enrage+ warmog's = well, I've already said what has needed to be said.
I have tried a Regrowth Pendant+ pots as starting game, but the lack of time lost when you get the Rod of Agesand the lack of AP and mana was a big loss mid game when I need it. Your mana dies so fast without it imo.
Hextech Gunblade - If the game goes late, its my last item I get for that extra damage, the life steal, and spell vamp. Otherwise, if you are getting nuked hard, either some armor via Thornmail or Magic Resistance w/ Abyssal Scepter. Hell or even another Warmog's. Its been a while since I have finished a gunblade.
