Focused a lot in teamfights or in lane
Pretty squishy until you have you Warmog's armour

When you reached level 4 and you have three abilities you can start hurras in this order, Sonic wave (Q) and jump to them then use your Temppest (E) and then fast use Safeguard back to a allied minion or champion.

When you reached level 6 you should use Sonic wave (Q) then Dragon's rage (R) and then activate your Sonic wave again (Q) and then use your Temppest and they pretty much should be dead from your hurrasing you've done before.

These items is very good if you wanna get a bit tanky but still have some heavy damage. you can try to switch around the items if you would like to but I particular like this order.

Flash and Exhaust is very standard summoner spells but if you like to you can use Ghost, Ignite or some other summoner spell you like. It can change around witch one u use depending on ur team's champions and summoner spells.

Thornmail : If you are against heavy AD team you can pretty much Fu*k them up buying this item.

Banshee's Veil : When you think you stilll lack some durability you can buy banshee's.

Stark's Fervor : It's nice to have one fervor in team because it gives pretty nice boost to everybody in your team.

Force of Nature : You are against LeBLanc who has 600 AP and insta kills you every time you fight her ? buy FoN.

Last Whisper : Enemies are stacking armor ? Solve that by Last whisper.

Berserker's Greaves : It synergises well with your passive, so feel free to take these boots.

Supports

Janna : Great support champ she has knock up, slow, shield which absorbs damage and increase your attack damage and of course her life saving healing ultimate.
Taric : Heal, stun and aura. What else do you want ?
Sona : True definition of support. Heal, movement speed boost, spell increasing attack damage and AP, aura's and AoE stun.

Carry's

Twitch : His brutal damage, slow and his finishing Expunge makes him great lane partner.
Ashe : Slow and global ulti with stun, with that you will get some easy kills.

Tanks

Rammus : You will love his op taunt while laning with him.
Singed : Extreme AoE slow and his Fling are just awesome.
