What's your best weird yet fun build?

Anti-Assassin Lux:

I used this against a team with Zed, Rengar and AP Ekko. They hates me since I always just barely managed to survive.

Life Steal Life Steal Quints Warlord's Bloodlust and Vampirism

During W: 107% at 100% Health and 196% at 2% Health (if W and Spirit Visage is multiplicative) This life steal applies completely to the damage being dealt by BorK and half applies to the damage dealt from Ravenous Hydra. Olaf will also heal from damage dealt through his Q due to Death's Dance. This will be boosted to between 6.25% of the damage dealt from his Q to 9.3% of the damage dealt from his Q.

Tanky Urgot adc, rush tear, then zzrot, ninja tabi, black cleaver, manamune, iceborn gauntlet,frozen mallet. The early tankyness really works well against most bot lanes and your passive makes it even better

Crit Garen

I did what I called "Hopped-Up on Coffee J4" in a custom game with some friends once. (We were just being silly, we didn't give a crap who did what or built what.) I ran so fast no-one could catch me.

LOL

Or in another one, I made "The Tankiest Nidalee this side of Rito"

+tank items. This build in ARAM is really enjoyable. Literal, overkill. Syndra ult is single target. Adds like 600 ad damage to your target with 5 orbs gives you some legit reason to overheat. Tank items are recommended.

rageblade+litchbane+nashors tooth on bard, land q snd attack twice. chunks them then keep attacking to get rageblade charged

. I don't understand why, but this can somehow solo elder dragon.

FULL AUTO ATTACK Skarner = easy pentakill the only way to not get bored out of your mind when playing skarner

late game is actually insane.

Lifesteal quints, Warlords Bloodlust,

The sustain becomes pretty hilarious.

I prefer attack speed Sion with the old devourer.

Have you heard of.... FULLAD ASSASSIN!

Q's that hit for about 1000 damage

Burst Bard. It's hilarious to watch.

with and the old devourer

It was hilarious when I literally deleted a full tank mundo in less than three seconds with that build
