What exactly is the best item for sustain after getting yoummu's ghostblade as first item considering you have the warlords mastery? (Particularly on Quinn)
If you're talking about sustaining from
Warlord's Bloodlust , you're looking for a crit item and since no crit item has life steal built in; The crit item you could get after Youmuu's Ghostblade is Essence Reaver. If you're looking for straight out sustain outside of crit, your best bet is Bloodthirster.
