"The death of a gauth would cause all the energy in their bodies to explode outwards as raw magical force."

This passage in the FR wiki drew my interest and would be nice to have in CoA too.

That wiki also says "The death of a gauth would cause all the energy in their bodies to explode outwards as raw magical force."

Sounds like a fun idea, can we please have them explode with a magical damage burst upon death?

Yep, in that case the setting should allow you stay stealthed or invisible, which would increase their use and improve the pacing.

As I recall disarming traps removes stealth. My suggestion to start with would be to enable rogues maintain stealth at all times when setting and disabling traps. That way they could quietly go on about their job while the rest of the party is fighting.

Yes, casters and bards elevate the party power level, that is their role in the party. With additional party members, quests are supposed to increase the number and difficulty of spawns.

I fully agree, however empowering traps and promoting a more thoughtful and cautious playstyle should go hand in hand with significantly extending the spell durations so that you're not rushed by ticking buff timers. Ideally, a single set of buffs should last during a quest, or between resting places if the quest has them. This means proper role can be given to planning, scouting, laying traps or their disarming.

From the webbed area in the Abyss to the Underdark there is an opening that you can transition through, however from the other side the transition is covered with a rockslide and you cannot return.

Accepting the quest in conversation with the questgiver NPC does not add it to the journal and you cannot enter the quest through area transition - it does/says nothing when you step on it.

We just did the quest with Theobald and it seems all good.

It seems the Firebrand scroll has been removed; I have not checked the others but there seem to be a few less lines of scrolls in the shopping window. Can it please be returned, as well as the others that may have disappeared?

ShadowRealm said Inowanna had taken them out because they were selling at 1/3rd of of the regular price but when I was buying them, their price was exactly like the price of other circle 5 scrolls so something must have broken it?
