AP gives you attack speed an on hit damage from your passive
passive damage + e damage = fast wave clear
E scales of AP and health, which we are getting both of
R does a lot of damage. > 1000 damage
the percent HP damage from E + riftmaker percent magic pen and bonus true damage will wreck the meta tanks

Always start red side going: Red - krugs - raptors - wolves - blue - gromp - scuttle - gank

high damage and attack speed
huge healing and shielding
clears very fast
destroy meta tanks
one combo squishy's
strong dives
can poke with e when sieging
can bait with low hp, only to get a massive shield from e and loads of health from r

low ability haste means longer ult and E cooldown
hitting both yourself and enemy with e is very important
your team might think you're trolling and if you lose they will blame you
can get bursted if e is down before you have bought defence

E-Q-Auto-W-R. full damage fast burst combo.
auto-W-E-auto-Q-auto-R. passive stacking burst combo.
whilst running away you can place E in the direction you are running from when the chasing enemy steps in the E, R into the E for massive damage.
Try stack your passive before going into the fight if possible
play around your e as much as possible, you can be vulnerable without it.
