What's the minimum level to access the Crumbling Caverns?

Question

The Crumbling Caverns is a new respawn added with the Between the Lines quest. It's located under the Ivory Tower, in Edron.

Between the Lines is a quest that requires lvl 200 to be finished, but can we begin it and access the Crumbling Caverns before lvl 200?

Answer 1

The requirement to begin the Between the Lines quest (and gain access to Crumbling Caverns) is to have previously learned the summon familiar spell.

This appears to be a somewhat unusual start requirement and is the only quest I know of with this type of requirement.

It does not matter what level the character currently is or if they are unable to currently summon their familiar  

I was able to enter the area on a level 190 that had previously learned the summon familiar spell while being 200+. 

Any other character I tried which had not learned the summon familiar spell was unable to start the quest with the NPC Phillip stating "15:45:09 Phillip: Please find the monster before it hurts anyone. But remember, this is a very dangerous task. You should be sure to have some assistance, preferably from a familiar you can trust."

Answer 2

To enter that place you need to start the quest and to start the quest you need the Familiar spell so you need to be at least lvl 200 or if it is a bazar char you need to see if that char bought the spell at least once
