Monster aggro

[Charismatic]

As far as I know, it only happens when you heal in front of them. Did you heal near the Smilodon? If you are level 90 and heal in front of a Goblin near Bastok in the present, they'll attack you for example.

The only "Too Weak" monster that attacks no matter what are the Detectors in Ve'Lugannon Palace and Defenders in the Shrine of Ru'Avitau. They are aggressive to sound. I can't think of any others off the top of my head.

Actually, no. But what I can say about it is having looked up the enemy's level just now... it's in the right range to aggro and actually shouldn't have been too weak in the first place (but I can assure you it did con too weak and also did not yield experience points). These things are levels 67-70, very odd for there to have been a Too Weak one in the first place.
Now I'm curious if that level range is correct on the wiki or if there's some stranger things going on.

You know what, a couple times now, there has been an Orcish Dreadnought in The Monastic Cavern where I've never seen one spawn before. I've been playing this game for 7+ years now and I have been through that place more times than I can count and NEVER had I seen it where I saw it - in the east tunnel at around G-8/9, south of the small open spot where the 2 tunnels meet up again and there's an Orcish Champion (which has always been there). The Dreadnought isn't always there, but the first time I went there and it was, I didn't notice it until I heard the grunt noise the Orces make upon aggro and I thought "I'm level 90, what the heck is able to aggro me in this tunnel... oh there it is."

Being around for 7 years, this wouldn't have been unheard of back in the early years of the game because monsters didn't used to despawn once the people who aggroed them initially died or warped or whatever. They'd stop, turn around and slowly walk back to their spawn point which would leave them to aggro anyone in their wake (sorry if you remember this time, just inform the newer players). I have, now fond, but then not so fond, memories of massive trains of bats or even skeletons being brought to the Garlaige Citadel's zone and then all of it wiping out parties. There used to be 3 or 4 parties that would be on the first steps just inside gaining experience and every last one of them had to zone themselves or risk being crushed by the returning monsters. I also remember this being used by a higher level DRG back when I was still taking my first job, THF, to Lv75 and in Yhoator Jungle. This individual decided to pull a Tonberry all the way to the Yuhtunga Jungle zone (which, with the distance from the first Tonberry to that zone line, he did it intentionally I think).
