Okay, this is driving me crazy. Where the heck is the key to the hidden jarrin root room in the subterrarium? I've looked all over the college and I can't find it.
In the Subterrarium there is a small pond beneath the area where the mushrooms grow. Look to your left to see a part of the wall that also serves as a secret door. There should be a handle near it. That should help.
Go from the yard in the Hall of Attainment, then inside straight forward through a door that say also "Hall of Attainment". You come to an enchantment room. Again straight through to a door to the Subterrarium. When you go through that door, to the right is a small table with a candle and the key. Found it a few days ago, i hope i remember correctly.
