PoE throwerere builds

I can get someone to help me with my Fire Shockwave Totem build? So the weapon/shield has 35% phys as extra fire while cast linked to searing bond totem (70% extra). Skin of the lords, +2 wand, +1 shield, +2 amulet gets me lvl 33 shockwave totem. I could eek out another level with lvl 4 empower or two with awakened. With my setup I have max 1 searing + 6 shockwave totems. with all totems up, tooltip dps shows 250k per totem so about 1.5m? I'm sure it's a little higher if I could properly check on pob. I honestly had higher hopes with the gear. There are some gems that still need leveling,

I know that people usually do it with Lightning/molten strike for attacks or spark for spells. I have another combo I want to try this with: Hydrosphere Vortex. The idea is to use vortex on m1 which should clear trash but also inflict a freeze/brittle on Hydro. Hydro has a bunch of extra levels + crit so should be good enough for map bosses/guardians. The method for Self-chill is Winterweave, Call of the Void + FR
