Well, toxic rain benefits most from + gem levels so either get a Lightning Coil with double corruption +2/+2 to gem levels (duration, projectile, aoe can get +2) or +2 and +1 to all socketed gems or go for standard toxic rain bow that can be self crated for 8 divines (or more if you are trying to get all t1 rolls):



Then second best source of DPS will be good +2 gem levels amu or if you have a good budget you can craft focused amulet for +4 gem levels.



Also roll on your boots searin exarch mode +4-6% action speed, it will increase movement and attack speed at once.

You can check also my POB however I took a bit different root. I'm at 89% all max res, high evesion and 97% physical damage reduction/converstion while still keeping DPS at like 47mln shaper dps. I feel pretty much immortal in 8 mods 10k whisp t16 maps.
