Granger: Best build, Counters

Capriccio

Granger's unique Demon Hunting Gun and Cannon are powered by Demonic Energy. Both his weapons start with 800 max Energy. His Gun restores 8% Energy per second while his Cannon restores 2% Energy per second. Killing a Minion / Creep permanently increases their max Energy by 6 / 6, and instantly restores their Energy by 5% / 5%, respectively. Each kill or assist on an enemy hero permanently increases both weapons' max Energy by 12 and instantly restores 10% Energy.
Every 1% Cooldown Reduction converts to 2 Physical Attack. Demonic Energy costs are not affected by Energy Cost Reduction.

Rhapsody

CD: 0.3

Granger rapidly fires 6 shot(s) with his Gun, with each shot dealing 60 (+45% Total Physical Attack) Physical Damage and consuming 70 Gun Energy. The last shot is guaranteed to Crit. While firing, Granger's Movement Speed is increased by 10%.
Granger stops firing when he runs out of Energy, or when the skill is cast again. Rhapsody has no cooldown and can be cast once his Gun Energy is over 420.

Rondo

Granger uses his Demon Hunter agility to dash in the target direction, instantly restoring 15% Energy for his Gun.
Rondo can be cast while channeling Rhapsody. Each time Rhapsody hits an enemy, Rondo's Cooldown is reduced by 0.5s.
