Spawning habits of rare mobs?

[tuamtuam]

I'm running through WW like a madman trying to get all the rare mobs, but only the trog is spawning regularly....I've bounced out and back in, checked all the secret passages,(except the WIZ runed one) but still have only found three of the six? I've killed the same three rares multiple times, and have been shown by a PUG where the others should spawn but they never show...So my question...how does spawning work?

Do rare's just randomly spawn on instance creation, so i have to recall and wait the 5 mins for it to reset? Do they only spawn at certain times, so it has to be night or noon or something? Will they spawn on the respawn timer after i've cleared an area or can i sit and wait for the respawn?

Game's been great up to now, but its starting to feel like camping trying to get these guys...Clear the dungeon check the secret rooms, clear the respawns check the secret rooms, etc, ad nauseum....

Either that, or get someone to run them with so u can just break then rejoin party to reset it; but to the essence of the question, yes.

Do they only spawn at certain times, so it has to be night or noon or something?
They say that timing is irrelevant....

Will they spawn on the respawn timer after i've cleared an area or can i sit and wait for the respawn?
You can not sit and wait for a respawn. If it is in the instance, it is there. If not, you need a new instance.

Don't get too upset about the explorer area objectives.

While providing a nice XP boost if you come across a rare or explorer, they really arent worth farming for.

The XP/Hour of explorer areas is a lot lower than running a quest. Not counting the first run through picking up all the explorer points of course....

As far as 'completing the game' is concerned, there are no further rewards (other than XP you gain at the time) that I am aware of for completing the explorer objectives.

There's no shared areas where you can gain XP so as soon as you zone into an instance, it is your (party's) instance. This eliminates all the spawn camping and ganking rubbish you see in other MMOs.

Oh, and welcome to Stormreach!

Welcome to Stormreach, M8.

Youll soon see that theyre not called "Rare Encounters" for nothing. :-)
You will will probably have to reset the "Instance" multiple Times if you want to get all of them.
No different Requirements other than being lucky have to be met afaik.
And for the Start all those Explorer- and Rare Encounter Quests give ok XP. And if you complete them you get additional XP, so dont listen too much to the Previous Poster (no Offense). :-)

Welcome to the game!

Some rare encounters are rarer than others. Most explorer instances have a couple that spawn every time, but there are also a few in each instance which have a substantially lower spawn rate. As someone else mentioned the rares are a nice little XP boost, but really aren't worth farming at lower levels.
