Guild Wars 2

So superior sigil of restoration heals on kill with no cooldown. If I use a mark to hit several foes, or hit them with minions, does the sigil heal when each of those foes eventually die?

Ie. if I hit a bunch of baddies with mark of blood, do they all get placed on the list of foes that will trigger the sigil upon their deaths, provided I get the kill credits?

Yes, marks trigger the sigils, it will only proc on one of the enemies due to the cooldown effect. I don’t believe the sigils are affected by minions as they aren’t weapons.

As long as you get credit for the kill, the sigil will trigger. The sigil apparently does not have any internal cooldown, so you should get healed every time you see the XP message on your screen.

Minions, phantasms and pets all contribute to giving you credit for a kill.
