Flash - Must have!

Flash is your only escape tool. It also gives you better chasing potential and repositioning.

Ignite - Preference

Rumble is a lane bully so it is good to run ignite to increase your killing potential. If your match up is hard/heavy fight oriented, I highly suggest picking this.

Teleport - Preference

Teleport is the best alternative choice for ignite. If you are not looking to fight during laning phase nor you feel like you won't have any kill potential, take this. Allows you to snowball from bot lane.

You should always take this. It simply outclasses other options.
+4,95 Ability Power | Gold value ~108
+14,85 Ability Power | Gold value ~323


You should always take this. It simply outclasses other options.
+0,87 Magic Penetration | Gold value ~30
+7,83 Magic Penetration | Gold value ~269


Most common Seal. Other alternative is Flat Health but in my opinion the Flat Armor is better choice.
Flat Health would give you better all-in situation in the early game but let's face it, you will never straight up fight till death. Flat Armor increases the value of health potions and health regeneration making it the better option in my opinion (Effective Health).
+1 Armor | Gold value 20
+9 Armor | Gold value 180
Effective Health?


Take these when against a composition which has non-existent Magic Damage or against a hard matchup where you need extra Ability Power for better results.
+1,19 Ability Power | Gold value ~26
+10,71 Ability Power | Gold value ~233


Most common Glyph. Take these when you are against heavy Magic Damage such as Ryze.
+1,34 Magic Resist | Gold value ~27
+12,06 Magic Resist | Gold value ~241


Take these when you are against Physical Damage while the enemy composition is heavy Magic Damage based.
+0,16 Magic Resist per level (+3 at level 18) | Gold value ~3 (60)
+1,5 Magic Resist per level (+27 at level 18) | Gold value 30 (540)

Your [passive] is a huge part of your damage output, so it's vital to maximize the effectiveness.

Proper Overheat combo; Every spell gets the Junkyard Titan 2 DANGER ZONE bonus effect and your basic attacks gain the bonus damage from Junkyard Titan 3 OVERHEAT.
When you have 2 spells, your heat has to be between 60-75
When you have 3 spells, your heat has to be between 50-55
Safest way to do this,
Engage with [E] because if it hits, it's easy to follow up.
Follow up with [Q] because if you miss calculated your heat and you get overheated, at least you get your primary spell in use.
And finally follow up with [W].
Note:[Q] and [W] are activated pretty much simultaneously.

When a [R] is added to the combo, it should be cast 1st or after [E].
