This build is focused mostly on Conditional Overload, as crit chance for the Kittag is (imo) bad.

NOTES:

• [Drifting Contact] helps keep the 12x multiplier for Blood Rush and Gladiator set bonus, but can be removed if you wanna go for more damage;
• [Virulent Scourge] and [Volcanic Edge] are theoretically optional, and can be removed, although this will result in not a only slower, but more unstable damage buildup, since this build depends on Condition Overload.
• Riven MUST HAVE attack speed and crit damage, and can have any elemental+ bonus, impact bonus, melee damage bonus or even crit chance(although elemental seems to give the best damage boost). You can also go for Status Chance on your riven and make the previous note have less of an impact, although you'll still be sacrificing damage if you do not add more elemental damage types.

POSSIBLE MOD PICKS:
(Swappable mods: Drifting Contact , Gladiator Might, Virulent Scourge or Volcanic Edge)

• Primed Smite X offers +55% damage, which is always nice.
• Sacrificial Steel gives a nice amount of crit chance, which will make damage more consistent and add more chance to orange crits.

Picking up speed
Running out of time
Going head to head
It's the way of life
You gotta fall down
Eat ground
And to get back up again
Let's Beyblade!

Spinning it out
At the speed of sound
Gotta rip it up
Now the bet is down
The team with the bang
Our gang is the one who's gonna win

Let's Beyblade!
Beyblade!

Let's Beyblade!
Let's Beyblade!
Beyblade!
