 * can hop over walls using . Place a ward next to a jungle camp and get inside a brush over the wall, then simply attack the monsters. However, make sure they're inside your circle. Also, when your reaches 9 Trophies, use the extra range on your passive to make this wall-hopping easier.
 * This is a great tactic for stealing epic monsters when counter jungling or killing the enemy jungler.
 * A great way to reach high amounts of attack speed very fast and burst down enemies is to use your and then your  right after (or the ). Because the attack speed bonuses stack additively this provides 90% AS at 1st rank and 150% AS at 5th rank.
