[ARENA-DMG BUILD] Thanatos

That's an incredible Thanatos build that works better on Arena games. I managed to make 2 pentas in a single game on my main and other 8 pentas on smurfs in a single day. You must be aggressive early in game, so you can make it work and maybe get a penta.

Have fun & Good luck !

The build it's based on Cooldown Reduction (30%/40%), Crit chance (40%), Pysical Power (275/250) and Pysical Lifesteal(15%)/Protections(15/60/65[Only Pysical]).

Warrior Tabi - The basic shoes, taking those instead of Ninja Tabi for extra damage. You can also take Ninja Tabi if you want more Attack speed, but you will deal less damage.
Hydra's Lament - It's a good starting item because of it's passive and because it gives cool down reduction and some damage.
Jotunn's Wrath - Taking care of the cool down and adding more damage, now your cool down is reduced to an acceptable amount. Giving some extra useless mana for Thanatos, but that doesn't matter.
Wind Demon - Adding more damage and trying to add critical hits, not enough yet, but it's ok because the passive gives us more movement speed, which will help before we build Deathbringer.
Short sword - Build that for more critical hits, which will help you move faster around your enemies and take less damage, making you a harder target to hit. Also giving more damage, you could upgrade this to Deathbringer before taking Bloodforge.
Bloodforge - It's the life steal, an optional item, you can use something else instead this, but I prefer to have life steal, because more it's better than nothing. You could use 'Masumune' or 'Stone Cutting Sword' instead. Masumune would give you more movement speed and some protections while giving pysical power (damage) too. Stone Cutting Sword also gives movement speed and decreases target's protections, so you give more damage. Also you can get some protections if you really need them instead of this.
Deathbringer - The maximizer for our damage and critical hits. Also giving a 40% damage extra on every crits from passive, great assassins item.

Before finishing the build you could take some extra physical power potions, if you have extra money, of course for extra damage. :)

RELICS:
- Aegis/Purification Beads = to protect you from different attacks, it depends of your enemies.
- Heavenly Wings/Blink = To move around arena faster, speed means kills baby. I prefer the "Heavenly Wings".

We are going to upgrade 1st ability as fast as possible because it's a good regeneration source and gives strong damage.
When you upgrade to the maximum the 1st ability you are going to upgrade the second one because you need speed to move around the Arena, so you can get as many kills.
Now, finally upgrading the 3rd ability, just in case.

You'll see that you will not really need the ultimate late in game, because you are going to get 1-3 hits kills, mostly.

+ High Damage.
+ Good Critical hits chance.
+ Good Cool down reduction.
+ High movement speed.
+ High health retrieve.
+ Over Powered late in Arena games.
+- Could work on Joust(3v3) or other game modes.
- You need a good aim with the 1st ability for getting early kills.
- You must be as fast as possible, because you can die as fast as the build makes you move.
- If their team work is good you may not be able to get many kills, but if you are a decent player you could get some nice kills.
- Could be easily killed by some mages with high damage. To fix that you could get some protections instead of bloodforge.
- May not work on Conquest, I didn't tried yet.
