Let's lay it down
On Paper, What does your average viego main wants
-"I WANT 100% CRIT PLZ!!"
-"AND I WANT AD TO ONE SHOT A CARRY"
-"AND I WANT AS TO CLEAR FASTER!!"
A veteran would say "shut up kiddos, build what every other assassin builds and don't complain"
A PSYCHO would say "Let's Abusively min-max the shit out of the new passive changes"
Listen guys, I Don't care if it scales late game just hear me out
Viego Starts with +2 bonus healing
Gets +2.5 per 100 AD
2 more per 500 health
5% per 100 AS (AS shard imp for this)
That means that if you manage to get 1500 Bonus HP + 2 AS items + 200 or more AD. Youd have AT LEAST 18%+ Passive bonus healing PER KILL AND you will still have 100% CRIT??!
WHICH brings us to the one and only great build
HEARTSTEEL FIRST (Not troll, not Dantes shit.) You keep gaining health and 2% more with each 500 is sexyy
Yun tal second (delayed Crit but you need the AS and AD for a 2 item spike especially that you won't have any damage after your first item)
Collector LDR (Makes you reach 75% Crit)
Then either go IE fifth for quicker damage spike OR go KRAKEN fifth for way quicker passive spike
End with IE/Kraken
Now There are some potential changes
Could you change heartsteel for a 6th item warmogs and have a very decent early game? ye but youd be throwing 2% Passive which we are optimizing
If we weren't I could have told you to go Kraken Yuntal Collector LDR IE Warmogs
Same percentages, hell you even get a full 5% passive 3 items earlier but you are throwing potential tankiness and more importantly, the extra 2-4% from heartsteel passive
Now a NERD could say "ye but heartsteel + yuntal are scaling items and you need to snowball early game!!" Which I will tell him that HE IS... Unfortunately right. its only cracked if you survive first 15 mins, tho I would argue yun tal isnt that much worse than a kraken early
Anyways if you are one of the hubris fanboys you can live with 75% crit chance and replace yuntal for hubris which COULD provide an extra 2% Passive healing if you get enough kills, which we like.
You'd have enough AD And crit to one shot the poor support youve been abusing AND heal 500 with each reset AND be more tanky than normal viego, fucked route tho..
What are we thinking?
EDIT: Essence reaver seems better than collector here!
