second, you are level 18 and I'm going to guess don't know how to cs well. Practice last hitting in general to increase your gold income
third, practice, watch streams, just play, read GOOD guides, etc. You will eventually get somewhat better, however you need to hold yourself accountable to do this, don't just aspire to get better, really practice (if you want to be better)
edit: also to restate an above poster, use smartcasting if you aren't already
I am not level 18, I am level 8. I meant when Ryze is 18. Also maybe I suck but I went 29-0 with teemo my 3rd game playing and I do just fine with other champs. I mean it has nothing to do with the balance of champs like oped teemo and a weak champ like Ryze right?
So I don't recommend doing this normally..... just for fun in random normals.....
But I have been having some fun with a full MANA SWIMMING POOL runepage starting mana crystal + 2 pots and as much mana as I can get in the utility tree and cdr in offense tree.
It is super gimicky but my level 1 damage is just so intense I just walk up to my opponent while csing and spam q on him every cooldown. and they just can't handle the damage, and I have so much mana I can do it about forever. A good player will get around this, but it is too good for random normals =P
