Dota 2
Legends of Dota 7.39b (Pick your skills, draft abilities, play with bots, make a custom hero, use any ability on any hero)
My ONE PUNCH MAN build (Magic Dmg)
Hero: it works with all heroes, but I choose SLARK .
Why Slark?
Well Slark is weak base hero but Slark is the only hero with 1800/1800 day/night vision, Slark is the perfect hunter for this build.

Skills:
  • SKYWRATH MAGE , Ancient Seal (this skill amplifies magic dmg your enemy takes and also SILENCES the enemy so blink skills will be LOCKED)
  • PUGNA , Decrepify (same as above, it also SLOWS and DISARMS)
  • CLINKZ , Skeleton Walk (great mobility ambush/escapes)
  • ELDER TITAN , Natural Order (increase both physical and magic dmg your enemies take)
  • SLARK , Shadow Dance (great way to recover missing health and great mobility/escape)
  • HUSKAR , Life Break (the one shoot skills, only aghs upgraded)

Items:
  • Aghanim's Scepter
  • Shadow Blade

Tips:
  • Check the map and enemy heroes skills/items (you dont want to get dusted, or get on Thirst threshold)
  • Dont stand too close of your enemies since Natural Order is a debuff aura (experienced players will blink away if they see a debuff aura and no one around)
  • You can buy Veil of Discord/Aether Lens to increase your dmg even more
  • With Aghs and Octarine, Life Break cooldown is 3 secs, also Shadow Dance cooldown is 45 secs
