Patch 4.22 Every standart build

Start with Deaths Toll for maximum sustain and bumbas mask for best jungle clear available.
Blue Stone Pendant is a great item if you are sure u can kill the enemys within the first 5 minutes of the game otherwise Deathstoll will outsustain Bluestone.

Devours rush is pretty selfexplainatory. More sustain great Damage and fully stacked an absolut boxing beast(arguably the best late game lifesteal option).

Warriortabis= more power better boxing and best suited for adcs with and attackspeed seroid(e.g.: cupid, rama, artemis.) The abilitybased hunters like ullr also profit a lot from warrior tabis since it makes ther abilities stronger. When youre not confident enough to hit combos just go for ninja tabis.

Executioner= Attackspeed + power + pen. Absolutley muswt have in any adc build. Get his as a third item since most enemies will have protections at this point.

Qins Sais: Power + Attackspeed + the best passive to take down tanks. (if they only got 1 frontliner consider getting a third crit item either poison star for more utility or rage for more coinsistend crits (=higher dps).

Winddemon: this crit item is standart for crit adc build since it givers you the best crit passive possible.

Deathbringer: when you go crit dont miss out on the glorious extra damage of this item. last item since you need the passives of the other items first.

Beads: must have get this first max asap
Aegis: almost must have since it prevents you from getting one shotted late game

viable options: sprint, ghost(odin counter)
