"Invulnerability" bug in quest "Striking Off the Chain".

[CHIPS]

Talking about this quest in Nonmoa Lake:

While doing this quest, the monsters will go randomly "Invulnerability" and regen all the health. This happened many times as I was ascending the poles. I guess the height differences in some areas are too great, resulting in this. I had to run away to "reset" the mobs.

After the quest I tried to ascend the poles for the vista. Same thing. So this looks like either a map bug or a height-differences bug. (Sometimes when you try to hit a mob from way up top, the game make the mob go "Invulnerable" to prevent abuse. e.g. c+1 spam at some location all day=free experience.)

Its a hight differences problem in general. What makes it especially annoying is that those invulnerable foes don't always break aggro but stay around and even attack back while invulnerable. Happens a lot in under water combat too.

[CHIPS]

I agree with you Gorani. But I understand the reason behind the invulnerability: prevent abuse in certain locations.

Maybe it is better to change the AI instead of this "invulnerability". The example:

If
1) Fight started for over 10 seconds.
2) Mob failed to attack even once (doesn't even have to hit, just have to at least swing his sword.)
3) Mob failed to cast any skills that damaged the player

Then run away.

Invulnerability should be removed by (1) using a melee attack on foe, or (2) being in range of a ranged foe.

I had a ton of problems with invulnerability tonight in Mt. Maelstrom. I went in to stealth on a skill challenge to backstab and the guy went invulnerable. On the 2nd attempt I fell in to the water and he reset to full health without even regen.

On the krait platform I fell in to the water repeatedly and got stuck underneath it, they went invulnerable each time.

Later I was doing the skill challenge against the slow attacking largos. He was attacking so slowing that I blocked every single attack and he went invulnerable. On the second attempt I went in to haste and used my evasive skill twice quickly in a row and he went invulnerable.

Too bad Anet doesn't read these forums anymore. I was not a happy camper.

I went in to stealth on a skill challenge to backstab and the guy went invulnerable.

That seems to happen at a lot of skill challenge guys. I reported that several times at three to four different skill challenges last week.

I have been on a thief playing rampage lately and this invulnerability is really pissing me off. Thieves revolve around not getting hit; blocking, blinding, evading, dodging and going invisible. Every single one of those resets the enemy. It's obnoxious. I'd estimate 5% of my fights go to invulnerability.
