Sorry for asking this as i couldn't see those details while watching the vid on my phone, but are you using a halo of arlyse ? Or have you considered it + ice armor, as your Viz pal Jaetch did ? I couldn't see what rings you equipped ...
Still, a great alternative to TR+SS. Gotta try. What solo GR could you reach compared to your personnal best ?
Do you know if nilfur's affix applies to each single meteor of the shower ? Which means meteor shower would be terrific against a single target ...
A WoH is already hard to find, but an ancient one ... lol
Edit : forgot to say : w/o frost nova you had a non CDR dependant build, which is a real change in 2.2 wizard builds. So i still believe Arlyse would be the real deal !
I use Focus and Restraint. This isn't a solo build, but a build made for speed rifts which usually range from GR34-45.
I don't use Halo because there really is no need for THAT much defense at the cost of THAT much offense. Especially at these "lower" levels.
Jaetch uses the Halo ring in his solo runs GR55+.
Each meteor "rock" gets their own individual Nilfurs bonus as far as I know. Making it extremely easy to hit the top bonus on the boots.
Some CDR is still required for more Flash damage, more teleports and more cold snaps, however you must balance CDR with RCR as well !
Thanks for reading.
