How useful is an HB mule nowadays?

I've been trying to make one...but considering the limitations of mules now...how useful are they to a mage?

They exist to reduce pot costs by alot.
By well over half for me.
Also if you get hit also it can reduce deaths (not paying attention and you can die at newts/skeles).

Definitely not required though.

i love my hb mule <333 so much i spent 40$+ exping her hair.. LOL! it saves my pots by 50% (no lie!)

but if you dont have 2nd computer next to you to constantly hb by hand, don't bother making one =p

HB mules are only for those who have a 2nd computer within 5 feet of them. If you have to run up and down stairs to your other computer so you can get more HP then might as well not make an HB mule at all.
