Are there any other sources of minion elemental conversion other than Triad Grip?

I suspect the answer here is no, but Triad Grip allow you to convert minion physical to elemental. Is this the only way to do this?:




I'm particularly interested in cold, but any would be helpful!

Churnobog's Pilar + Necro Aegis.

Colds super hard, probably deliberately. You are kinda restricted to 4 green triads for that one

physical to lightning support gem should work when linked to the minion skill gem.

Grip of the Council allows converting physical damage as extra cold damage, which is useful if your minions already convert to cold or another damage type.

If the damage is purely physical with no previous conversions, a Triad Grip with four green sockets is the only way to go.

OK, thanks everyone. Triad it is :)
