Help me make sure this is going to work

Here is the idea: I hit with hammer, screen explodes in several lightning spells

I am farming last flames, so the next one that drops (I have already found 2 this season). I will have plenty of divs to put it together.

Temporalis, for cooldown of all the skills to be able to proc on almost every hit.

Druid for guaranteed crits on all hits

CoC with lightning orb

2 mjolnirs. One with ball lightning, this would start the orb moving. The other with spark, to get a bajillion crits.

Choir of the Storm - auto lightning bolt with every hammer hit, spark hit, orb hit, and Lightning orb

Andvarious ring, kalandras touch and ingenuity. Giving me over 200% rarity find

Vortex helm with +4 skills and "equipment has no attribute requirements" to bypass the high attribute cost on mjolnirs

Gloves and boots needing maxed out fire cold and chaos resistances.

Then just slam all the skills with +skills and energy collection

3 grand spectrum sapphires to get another 54% res all

I can't decide on running blink, harold of lightning, CoC, or other persistent spells....

Please let me know if I am missing some interaction... as this sounds like an easy "just swing a hammer" to get 5 skills hitting constantly.
