While playing as Ziggs you need to care about distance between you and your enemy, if you care about distance then you will be able to lead the game without taking too much damage.

ZIGGS, THE HEXPLOSIVES EXPERT

Ziggs was born with a talent for tinkering, but his chaotic, hyperactive nature was unusual among yordle scientists. Aspiring to be a revered inventor like Heimerdinger, he rattled through ambitious projects with manic zeal, emboldened by both his explosive failures and his unprecedented discoveries. Word of Ziggs' volatile experimentation reached the famed Yordle Academy in Piltover and its esteemed professors invited him to demonstrate his craft. His characteristic disregard for safety brought the presentation to an early conclusion, however, when the hextech engine Ziggs was demonstrating overheated and exploded, blowing a huge hole in the wall of the Academy. The professors dusted themselves off and sternly motioned for him to leave. Devastated, Ziggs prepared to return to Bandle City in shame. However, before he could leave, a group of Zaunite agents infiltrated the Academy and kidnapped the professors. The Piltover military tracked the captives to a Zaunite prison, but their weapons were incapable of destroying the fortified walls. Determined to outdo them, Ziggs began experimenting on a new kind of armament, and quickly realized that he could harness his accidental gift for demolition to save the captured yordles.

Before long, Ziggs had created a line of powerful bombs he lovingly dubbed ''hexplosives.'' With his new creations ready for their first trial, Ziggs traveled to Zaun and sneaked into the prison compound. He launched a gigantic bomb at the prison and watched with glee as the explosion tore through the reinforced wall. Once the smoke had cleared, Ziggs scuttled into the facility, sending guards running with a hail of bombs. He rushed to the cell, blew the door off its hinges, and led the captive yordles to freedom. Upon returning to the Academy, the humbled professors recognized Ziggs with an honorary title - Dean of Demolitions - and proposed that he demonstrate this new form of yordle ingenuity in the League of Legends. Vindicated at last, Ziggs accepted the proposal, eager to bring his ever-expanding range of hexplosives to the greatest testing grounds in the world: the Fields of Justice.

Ziggs is a good farmer. If u are farming remember that perhaps someone from your team need the money so dont be greedy. Ziggs Bouncing Bomb(Q)ability is the best way to farm but remember you musnt be greedy. I had idiots couple times and they raged because of my farm, so this can save your game if you keep it on mind.

I took Ignite for Ziggs because it is good for finishing mid chamions. Next i took flash because you will use the ability Hexplosive Minefield(E) and Satchel Charge(W) much more easier and you will rarely lose kill.

Even if you're far from a fight you can still help from afar with Mega Inferno Bomb.
Slowing your enemies with Hexplosive Minefield makes it easier to land other abilities.
Knocking yourself over walls with Satchel Charge can be great when chasing after or escaping from enemies. Remember that from the longer distance you use your ulti it will travel longer.
