At what level does pet stop needing torch to dual wield?

[Yami Blind]

Topic says it all,

I have both MAG and NEC so an answer for both would be delightful

I almost torched my Invoke Death L49 pet spell, but briefly glanced over a handful of combat logs (nothing conclusive sadly) and it *looked* like he was dual wielding and double attacking

Would love confirmation so I can stop carrying these dumb torches around
