Primary path on Draven
Domination improves burst damage and assassination tools on Draven. Most of high elo players – and our LoL pros in the the major regions – have agreed that
Hail of Blades is the best keystone rune to run on
Draven. This keystone rune helps you to win short damage trades in your lane by increasing your attackspeed at the beginning of a fight. This is usually followed up by taking
Taste of Blood,
Eyeball Collection and
Ravenous Hunter.
Taste of Blood heals Draven as soon as you damage an opposing champion.
Eyeball Collection is next up. This grants the user additional damage with every killing they score.
Ravenous Hunter is the final rune of the
Domination path. This rune gives some survivability during short fights and damage trades during the laning phase. The additional health is nothing to scoff at and can mean the difference between winning or losing a battle.
Secondary path on Draven
When it comes to your secondary path, most
Draven players prefer to go with
Precision.
Precision improves attack and sustained damage on Draven troughout the match. On the
Precision path, the best runes for Draven are
Presence of Mind and
Legend: Bloodline.
Presence of Mind helps Draven with the mana problems by restoring missing mana, if a champion is killed.
Legend: Bloodline gives life steal, which aids in winning damage trades and fights in the later stages of the match.
