Welcome to my ultimate Olaf guide for 3 Vs 3. This build focuses on high health for max survivability and because of Olaf's [Vicious Strikes] and Atma's Impalor for a high damage output.

I've tested this build out alot now and I've been able to carry rather bad teams and still win. :)

Pros
- High DPS.
- Tank slayer with Reckless Swing.
- High HP so you won't be targeted in a team fight.
- Very strong when at low HP but most people will underastimate it.

Cons
- Fragile early game with first blood (never engage alone).

For runes I chose the standard:
- armor pen. marks: Just straightforward the less armor the enemy has the more you hit. ;)
- Flat armor seals: For a little bit of extra survivability.
- Flat atk. speed Glyphs: Faster atks = more dmg duh.
- Armor pen. Quintessences: Same like the marks less armor more DPS!

Just a standard 21/9/0 build for maximum armor pen and crit which will let you crit about 500-600 on enemy champions with 50% dmg reduction.

The reason I chose for early hp is for maximum OPness end-game.
End-game you will have about 4k health if the match lasts long enough.
With a medium long match you will have around 3-3.5k hp.

Undertow is a nice ability for both harrassing and clearing creep waves mid-late game. Undertow is also a good ability to regain some health together with vicious strikes.
