Is there a general level at which an npc should summon?

Are there special circumstances involving it?

Discuss.

it depends on the mob iirc. some did, some didn't.

lvl51+ except some yardtrashexp mobs afaik

starting at 54-55 almost every mob summoned (?)...memory is blurred

For some reason I remember it being 49. I figure there are a lot more druids or necros that would know good details.

I have only found one reference to support this

revultant rats were always lvl 49, afaik.

Hmm, summoning always was interesting, but I always felt that it was something that should be reserved for named mobs, or at least 'special' types, like a 'shaman' amongst warrior mobs.

for example, geonids (lvl 44-48) in western wastes & raptors (lvl41-44) in timorous deep can bring you up to lvl 60 solo. both mobs dont summon and have been always camped by soloing players.

so it looks like you are right nilbog

ps: (and this backs up my theory that clr+mages are the best combo 50+ :p )

Another question... what all can you be summoned for doing?

Example: I partnered my magician with a druid in Western Wastes. He would cast snare on an Ice Burrower... and recast it over and over again, building up hate but never being summoned.

This leads me to believe that at least 1 point of damage/healing is required?

iirc nilbog, you had to do DAMAGE to be summoned.

EDIT: but like you said. snare no damage spells would not cause summons.

ya i remember it was like 2% of the mobs health before it would start summoning

No.. if you go up to Lord Nagafen, nuke successfully and run away, you're guaranteed to be summoned as soon as you're out of his melee range.
