Need some tips on my Magma orb Templar

So I have been trying out a new build that I made (Or I havent seen this build before atleast) and now I just want your guys oppinion on how it will do =)

I play at Standard League and 90% of the time I play with a friend that is tanking.

This is how far I have planed atleast. I´m only lvl55 right now but the tree goes to 67.



My gear is really bad right now so I take any tips on what gear I should get to optimise my build.
Is this build viable or do you think this will be complete dog shit at the higher levels?

Regards
Fempflar!

Have you try Magma + LMP + Faster attack + Faster Projectiles / life on hit?
