Jungle Altar Barriers Block Entry 1/2 Of The Time

The boss altar for the passage quest has an invisible barrier which is just outside the boss room, so far five out of nine times I've gone there. The passage is quite narrow, so I don't know how I'm missing a plate or trip wire, if that is the issue. I have noticed that it seems to go up if I take too long to enter, if I get inside the entry tunnel and then afk, or even just sort my inventory. The two times I charged straight down the passage I got into the room.
I assume it is there to force you to enter the room and fight, and not cast spells from up the corridor. But I have only done that twice, the other three times it was just up and I hadn't cast any spells in the corridor (i think).
Hope this helps.
Oh I agree with other posters that the boss is too hard for a required kill at the quests level.

 

What boss is this? Haven't done the new the passage quest yet.

 

I'll look into the teleporter failing to work, but as for the boss's actual difficulty, it's an Altar Boss. These are generally much tougher than normal bonus bosses; if it was the difficulty that the other altar bosses were at it would be way harder. Admittedly, this is above the par for a normal boss, but not by too terribly much.

Normal Lv 60 boss stats:

Health: ~21000
Regen: 5%, 1050
Damage: ~460 at Attack Rate 1.0

Tribe Zombie Chief:

Health: 28000(~1.33x multiplier)
Regen: 2.5%, 700(~0.67x multiplier)
Damage: 550-670, avg 610(~1.33x multiplier)

So, overall he's about 33% tougher than a normal boss of his level, but he has an air weakness and subpar regeneration that he needs to rely on his easily-knocked-back, fire-weak healers to overcome. Those other Tribe Zombies are rather slowpokes, despite their numbers, so it isn't anything that you shouldn't be able to handle at this point in the game, considering there are other Altar Bosses before this that are honestly much much tougher.

I mean, Rymek Luke has just over double the health of a boss his level and deals 500 damage per hit! At Lv 40!

 

Another jungle boss that essentially forces mages to use sunrise, you really like at wand, don't you?

 

Use Ciocca? Sage? Sunsetter? Alaxica? Literally any wand with an air powder?

Or, alternatively, you could utilize just -not- an earth weapon...he doesn't even really have that much earth resistance(65). He doesn't resist fire, water, or thunder at all, as well. It isn't like you won't be able to wear him down, he has lower than average regeneration as I noted. Considering I beat him with a fire/water Wirt's Leg...?
