In my opinion, Engineers or Mechanics should be experts in taking down structures or greatly boost the production efficiency of allied buildings or the combat efficiency of mechanical units. As for the Engineer or Mechanic itself the arsenal should technically consist of ingenious or well designed traps, grenades or portable combat units that are quick and easy to deploy.
1) This option is more for a Engineer or Mechanic that can easily dispatch clusters of attackers, excelling at canceling the numerical advantage of the enemy.
- Q - Raw Petrol Canister - Throw a oil filled canister at the target location slowing the attack and movement speed of organic units by X%. Leaves behind a temporary oil spill that persists for X seconds, enemy units that step on the spill that slows the movement of enemy units. Enemy units affected by the bomb's target location suffer double attack and slow speed reduction.
- W - F.R.I.E.D. - Unload the entire petrol canister of the weapon to cause an explosive burst of flame in front of the caster. Enemies affected by this ability suffer instant X damage and have their armor reduced by 3. Enemies that are affected by Raw Petrol Canister debuff get ignited and suffer damage X over time for 5 seconds. This ability damages both ally and enemy units.
- E - Tender Love and Care (TLC) - Due to the nearly obsessive daily maintenance, everything in the arsenal is freshly oiled, cleaned and in prime condition; they will never fail in battle. Reduces the cooldown of Raw Petrol Bomb by X. Reduces the mana cost of Hellfire Blast by X.
- R - Blaze of Glory - After a short delay, a massive fiery explosion is released on a X radius around the hero. All units and structures caught in the radius instantly suffer X damage and are stunned for 6 seconds while the hero loses 20% total health in the process. When the hero's health pool drops bellow 20% this ability is triggered automatically. 120 second cooldown.
2) This option is more for a Engineer or Mechanic that focuses on controlling enemies rather than dealing damage. Unlike the first option, there are no skill combinations and the Engineer or Mechanic has a way to replenish the mana pool in order to keep up.
- Q - Smoke Curtain - Throws a smoke bomb at the targeted location. Enemies that enter the smoke curtain have a X% to miss their attacks.
- W - Electroshock Bomb - Throws an electrical bomb at the targeted location. This ability deals no damage but will drain X% total mana and remove buffs on enemy units caught in the area of effect. Weak summoned units (Ex: necromancer skeletons) are instantly killed.
- E - Magical Intrusion Rearranger - This ability can be set on auto-cast and cost 0 mana to use. Dispells debuffs on self or ally units. Per debuff dispelled gain X mana points.
- R - Ultra-Flash Reflector Shield - Once activated this ability will return all incoming damage back at the attacker. X.X mana points are drained per damage point taken.
3) This option is more for a Engineer or Mechanic that favors summoned custom built units to aid in battle. Additionally, the hero can enter an Avatar-like state gaining access to devastating abilities temporarily.
- Q - Mechanical Wolf - Summons a mechanical Wolf to fight at your side. The Wolf is melee ranged, has normal attack type, heavy armor, critical strike, resistant skin and Howl ability.
- W - Mechanical Scorpion - Summons a mechanical Scorpion to fight at your side. The Scorpion is ranged, has piercing type damage, medium armor, slowing poison and Endurance Aura.
- E - Incendiary Ammunition // Ignite Weapon - This ability can be set on auto-cast, costs X mana per attack. Empower your basic attacks to deal stacking damage to your target. Each stack reduces armor by 1 and deals X damage points per stack. A maximum of 5 stacks.
- R - Stormsteel Destroyer - Become the Stormsteel Destroyer, temporarily granting you enhanced combat capabilities and access to new abilities that cost no mana. For the next 20 seconds gain bonus X armor, X health, spell immunity, deal 200% damage against buildings and gain Chaos type attack. Q for Thunder Clap, W for War Stomp and R Destroyer's Wrath (can be used only once, unleash a massive shockwave in a 360 degree radius around yourself and deal X damage to enemy units and structures)
