Thade looks like headsman - humpbacked male with black robe and hood. He's holding giant scythe. He's melee fighter with 175 attack range. Additionally his skills haven't got mana cost. So let me introduce his skills:

[Passive] Pact with Death - For every kill and assist, Thade receives 1 stack of Pact with Death (2 for scored kill). Each stack allows him to respawn 10% faster, however all stacks are lost upon death. Max. 8 stacks.

[Q Skill] Slaughter - Thade cleaves all nearby enemies around him, dealing physical damage and additional true damage equal to target's missing health in %. Half effect to enemy minions.

  • Physical Damage: 65/90/115/130/155 (+0.65 total attack damage)
  • Bonus true damage equal...: 4/5/6/7/8%
  • Range of AoE: 425
  • Cooldown: 13/11.5/10/8.5/7 seconds

Great AoE skill to deal massive damage. However it's cooldown doesn't make this skill spamable.

[W Skill] Stalking - Gains stealth for 1 second after use. Additionally Thade gains increased move speed and reduced crowd control effects. Lasts for 4 seconds.

  • Bonus move speed: 8/14/20/26/32%
  • CC reduction: 20/25/30/35/40%
  • Cooldown: 24/22/20/18/16 seconds

Great to suprise enemy from bush or just run from him.

[E Skill] Death Touch (Passive) - Gains chance to deal bonus true damage with next hit.

  • Chance: 15/20/25/30/35%
  • Bonus true damage: 25/40/55/70/85

Well, this skill can save your life when fighting.

[R Skill] Demonic Dash - Rapidly charges to enemy champion, dealing his basic attack with increased damage. Thade is untargetable for the time, when he dashes.

  • Increased Damage: 15/30/45%
  • Range: 650
  • Cooldown: 40/35/30 seconds

With it's long range you can easily last-hit enemy or just initiate fight. While dash animation, there's something like lion who's black and burn with black flames. After reaching his target, Thade starts to laugh.

Epilogue: Thade is great on every line. As jungler, his ganks are great even without 6lv. Combining stalking with dash cause you to win almost every 1 vs 1.

Waiting for your opinions ;) Thanks!
