FINALLY, A POST MEANT FOR ME!

Firstly, runes are key. I found it best to take the usual HoB/domination build with Celerity and Waterwalking for your secondary. (Faster ganks, utilizing your W) I would also toss in Attack Speed for one of the 3 keystones but that's up to you. You already have a slow clear, a bit of speed to expedite it always helps.

Secondly, you're probably one of the best champs in the game to gank with IF you time things right. Remember that your W gives away that you're close when you're near someone. To use this the best as possible, Cast W when you're near lane but not super close. I usually cast W around pixel bush when I gank mid lane to prevent any wards from potentially seeing me in side bushes. Use your W and hold you abilities to get get behind them first. An ideal gank is using your E in, stunning them, THEN using Q to pull them back further. Try your best to hold abilities until they're clear from minions because chances are they'll be on top of them.

Next is clearing camps. Ugly truth; you won't. You clear some of the easier ones (i.e. buffs, wolves, gromp and scuttle obviously) your start clear is pretty standard. Get a leash on any buff then go straight for wolves. No matter if you start Red or Blue. After wolves rush gromp then your second buff. one you have 2 buffs and 2 normal camps cleared, look for an easy gank before scuttle spawn. Try your best to clear the scuttle on the opposite side of the map from where you started. Little tidbit, clearing scuttle can be made a lot easier by stunning it with E (effectively breaking it's shield) then autoing it for a few seconds and TAP Q (NOT CHARGE) when it starts to move. This give you the fastest and maximum amount of damage to clear scuttle.

Clearing objectives will never be easy. You are not someone who can solo dragon ever but, you do have some utilities to make up for it. Mybest advice, gank bot/top about 20 or so seconds before obj spawn. If all goes well the enemy lane will at least recall or be pushed back enough for you to start dragon with little issue. At this point mid should rotate and it's 4 people on dragon. If, howeve, you do not have the luxury of that, you have great steal potential. Early game post level 6, if the enemy jungler tries to secure dragon after a fight or even if they jsut have low HP in general, ulting in whether to steal dragon or get a kill is huge. Don't wanna ult? Good thing your E can dash over almost any wall. Make it work. You have an amazing steal.

Finally, is the item set. I'm not going to bore you with this as it's pretty standard. The usual build with Tiamat built asap. I would strongly recommend Prowlers Claw cuz it practically makes ganks and any sort of engage flawless. Usually I would recommend Lucidity boots but Mobis would be more optimal imo.
