Rune and sigil choices for MM?
Spiteful talisman has always been a better choice for me. You don’t really have the luxury of staying in DS very often at all (pretty busy keeping minions summoned and setting things up for them), and the extra boon stripping (or forced dodges) and the regen/vuln are pretty big imo.
Lich is bad for your build. You aren’t a condi MM, so you’re only benefitting from the 6th rune (which isn’t good enough), and that condi damage is basically useless to you.
Lyssa is great, imo. I don’t usually use it, but it is an awesome rune set, and because Golem is not only such a short CD elite, but also procs on summon and active, you get a lot of uses out of it.
I’d also look at a 4set of Vampirism, and melandru.
For sigils, I generally use Leeching or Hydromancy for on-swap, bloodlust on my dagger set (you want to finish people off with dagger out anyway for the LF generation), and Hobbling on Axe, as it increases not just Axe 3 but also Golem’s and Bone Fiend’s cripple durations.
