DISCLAIMER:This dude is HARD TO PLAY.

Okay first let's talk about the Weapon: Inferno Gloves (This is the best weapon to equip imo because it is his only weapon to give him a skill power increase. plus it has a nice Attack Damage and Critical Damage boost which is incredibly helpful on this Basic Attack reliant Champ.)

Now onto the Badges: I can only think of one Badge that is increadible to use on him and that is Hard Learner (When you get KO'd your max energy goes up which so useful on Vooghoul.)
You could use Heart Bomb to stack with his trait but it's not recommended.

Now for the Training routine:
Strength: Bowling x5

Endurance: Extra Batteries x5

All-Star: Coffee x3
Aromatheropy x2

The Training Routine is pretty self-explanatory.

I could go on for hours and hours about how great this guy is but I'll keep it short.
Let's begin with his more noticable factor, His damage. You might think all of his damage is coming from the Skull of Death but no, far from it. Belive it or not his greatest damaging tool and the starter of all his combos is his Basic Attack. His Basic Attack is no ordinary one, to start this off, it isn't a projectile but it attacks from a long range, The auto attack throws a bomb on the ground where you aimed the Basic Attack ,(This has Omniversal range, meaning you can shorten or Expand the attack range up to a cap) you can have up to 8 of these Basic Attack bombs which can be detonated with his first Skil Detonate. All of the current bombs explode and deal 110 Elemental Damage each to all enemies around them. That is around 800 damage from one skill! But thats not all, you still have The flying-Rage inducing-Team Healing-Enemy Destroying-Skull of Death (aka Infectious Curse).
Infectious Curse in the most infamous of his abilities to do the most damage but it isn't, it is still a very strong skill and it also makes me think why Vooghoul is considered to be Defensive rather than Offensive or Supportive as it is a Single Target nuke which heals your team when they attack the infected Target. You can effectively turn a Scathe or a Minos into a Healing Station. Infectious Curse has a power of 200 which is very stong considering Vooghoul's kit.
Now last but no least we have the Nether Bomb which is one of the strongest abilities in the game. Not strength wise but in Utility. Nether Bombis a ranged AoE ability which creates a rift and Enemy Champions caught in the radius of the initial cast will be pulled to the center of the radius. After 1.5 Seconds of casting, the Nether Bomb will explode and deal damage to all enemies inside it's radius (Even those who weren't pulled) dealing around 160-170 damage. This skill, this freaking skill is what ties this guy together with a knot of ownage. If you're a quick-handed player, you can easily lay out 8 bombs and lure your enemy into the middle with Nether Bomb, Dealing massive damage and throw in a skull of Death just to piss them off. With this combo, you have already dealt over 1000 damage to 1 or more enemies!

That is in as short as possible a good explaination of how to use Vooghoul and why I find him so good, but there are a couple thing I don't like about him.
1. He's too squishy
and
2. His 2nd trait is not very good

thanks for reading my guide, this si the fourth one i've made so far and i'm trying to improve the quality with each guide. Support will be solemnly appreciated.
