AG Puppeteer Chains of Command support gems ?

For this Phrecia event i decided to make an AG Chains of Command build with hte Pupeteer acension

my AG is usin Rathpit (not foulborn) + the grey Wind + Crown of eyes
with doppelgängar suit , gravebind gloves and legacy of fury boots

so im just wondering what would be the best gems to put into the chains of command armor for the manifested weapons flying around

my current setup is
Elemental Damage with attacks
Ruthless
Multistrike
Combustion
Minion damage
minion speed

sofar its going very good in yellow maps but im starting to see the damage drop off and i dont think itll be very pleasant to do some of the pinnacle bosses or maybe even t15-16 maps

ive yet to get my hands on any cluster jewels so i know that would be a good boost aswell
