Passive.
Increases mana regen by a portion of Techies' max mana equal to 0.08% + 0.02% per level.
When Techies die, they leave behind a barrel that explodes after 1.5s, dealing magical damage equal to 50 + 30% of their max mana to enemies in a 400 AoE. The barrel provides 400 obstructed vision until it explodes.
Increases mana-to-damage by 10%. Adds an active component — Techies plant the M.A.D. barrel and detonate it later via a sub-ability. The barrel is invisible and can be destroyed before detonation begins. Detonating makes it visible and immortal, then it explodes after the same 1.5s delay. Only one M.A.D. can exist via the active cast at a time. Barrel Health: 200. Cast Range: 450. No Mana Cost. Cooldown: 30s. Cast Point: 1s.
