You will not evade me, $name

Basically, if you were in melee range and the mob would turn to you and hit you, you'd get summoned if you were farther than his melee range.

Like if I cast an ice comet from afar, and tank has just enough aggro that the mob wont run to me but that if I were in melee range it would hit me. It would summon me(wizard).

Hope that makes sense.

Correct - as of Kunark any mob 51+ when spawned would summon from 97% of health onwards. Gullaback in Burning Woods is a great example of this as he can spawn as a level 49 - 51 mob. Only the level 51 version would summon you. Now there were exceptions to this but the above rule pretty much stood as a base marker.

I remember that there being 3 levels of summoning...

#1 - Summon after some damage is done. This is the most common variety as I remember it. This was a % of the mobs total HP (2-3%), I know this for sure because I would sometimes go and try killing raid mobs and if I felt like I was not going to win the fight I could somtimes stop attacking long enough for them to regen back up to 97% and then I could escape because they would stop summoning. Granted this was with Luclin raid mobs (Ssra mobs primarily), but I think it is the general rule.

#2 - Summon on aggro. This was a special case..some mobs would summon with no damage done. As soon as they had aggro they would start summoning. I know I remember this being in, I just cannot recall any mobs off the top of my head that did it.

#3 - Summon with Spells. Specifically Call of the Zero, but I think all of these were Velious Raid mobs
