this is just something in general (although the gun blades and revolvers are something i generally tend to keep on fiddle.) Rabadon's the void staff and malady are quite helpful though.

well the gun blades as i have mentioned before can be used on any caster for its spell vamp and AP but i prefer you all to add your own items as well for needed improvements that i may have missed. you also you depending on your caster once again may need a survival item or so,you will need to sell the ring for whichever item you see fit.

The runes i use are just guidelines for you.Depending on the situation i use different lower tiers,so use whichever you like.
