An extreme Watery Seam

[Scrappa-yeti]

I can see the quest "A watery seam" getting run successfully by a good (and possibly specialised) team.

But for a normal bunch of adventurers/players, it is pretty damn hard. I think it deserves the QA safety sticker.

If "Lord Dreadskull" is a very hard, this deserves at least the same, possibly higher.

[The Old Hack]

This quest is kind of scary, yes. Especially if you are going in blind.

[Time_Stomped]

Change phrasing to saltwatery seam and people will get the idea eventually.

I almost soloed this quest on a level 7 fighter with a low level wizard following me around not doing anything. It is scary yes, but not nearly as hard as darkskull. It probably deserves a "difficult" rating, and it is probably harder the more people you have. I got the end boss down to badly wounded but died to bad back to back rolls and a reluctance to drink potions.

[Scrappa-yeti]

I am up to five runs of this now, I think, and people have died on three of those runs. Now it might just be bad luck, but it does seem pretty high.

If you are coordinated and especially if you have done it a few times, it becomes manageable. But if you have done it a few times, you don't need the warning!

I think anything that takes that many PCs deserves a safety sticker. I have not seen 60% of Darkskull runs take a life.

It definitely seems quite a bit tougher than it was back in EfU:R which can be very jarring to people entering expecting the former difficulty. A very specifically built group definitely has advantage over a random hodgepodge. For random hodgepodge groups if they're willing to pull monsters in small groups, and possibly put on their armor while under water the difficulty greatly decreases, but I'm pretty sure both of those things aren't smiled on by the DM team.

As far as I am aware it hasn't been modified at all from when it was reliably crushed for supplies.

Having done it twice in this setting I don't think the quest is any harder than it was in v5.
Its just the annoyance of being underwater as usual.

[Charnelist]

I honestly feel that this issue can be placed on the 'growing pains' of transition to a new chapter. Things in v5 are a little harder, as progression is slower and the setting isn't one we're intimately familiar with on any level, including mechanically. And other reasons besides.

I don't know that it matters whether the quest has undergone any changes, or that a well-prepared group - or quest-savvy group with foreknowledge - would do well here.

On the basis of this being an easily discovered quest which is unique in its dangers, I'd suggest giving it that safety sticker. It's tricky, opinions on actual difficulty aside. It couldn't hurt to say so.
