Mana is a must for this guy to keep up in any game.
Without mana farming gold is limited to 60-65 auto attack damage good luck.

Primary escape combo- E W Q - running for life
Secondary escape combo W E Q - more damage might get them to back off
Note. W E Q if enemy has abilities like Yi's Q !!!!

Farm jungling possible, gank jungling possible, solo any neutral monster possible. Best wave clearing ive seen in my whole time playing league.

If you can solo baron you can solo any enemy just might take longer and a few tries to get the kill ha lol. Ryze's mobility is lethal try to catch him. Prefer fights where there is minions to life steal from and land huge damage by e q deaths on minions for a prox to land on the enemy full combo q e q w q e q r etc. Team fights stay back let them do the work and stay in range of closest enemy to land devastating blows inside of your security.

Early Slow and need to deal with constant harassment while trying to land 60 ad auto attacks keep mana high for the engage/disengage, late game- prioritize e on weakest minion ( if weak enough to kill with e aim through the rest of the minions as to avoid missing q ) follow up with e on minion closest to unaffected minions, finish with q .
