OK, so let me say straight away that I am a relatively new player to LoL so would prefer constructive feedback rather than flaming please :-D

This build is just something that works for me and that gives me some nice scores.

I chose these runes as they are quite cheap but pack a nice bit of punch in-game.

Pretty standard setup on these i'm afraid, just geared up for armour pen to match the runes.

Again, these are pretty standard items for quick damage but i've tweak the recommended slightly. I like to use the Chalice so it enables me to have Frost Shot on 100% of the time from around level 11....which, to be fair, is when the team fights generally start happening.

makes sense when you look at the items.....try and minimise the use of Frost Shot where possible in the early levels but keep levelling it up so once you have got your Chalice you can slow your enemies for sheer fun!
