A just reward. The developers should be ashamed.

I have potions of invisibility and found the alternative route to escape the courtyard via the wall.
I have tried 10 times already to escape. Not only does the hydra see me through my stealth, I can't even climb the damn wall. I get two tries before the hydra kills me.

What poor design, I do not believe this game has been playtested on difficulties of normal and above. Even if I manage to gather the nerve and get lucky with my rng, small things like this piss me off because they don't alow me to experience the rest of the product I've purchased.

Fix this.

If you refers to the verdant chambers the escape is largely doable. Potion of vanish, scroll of haste and just run, drink another potion of vanish if needed and then leave by the wall.

[jaypob]

You just have to figure it out. Why are you failing to be able to climb the wall? Are you carrying to much weight? WIth the appropriate potions or scrolls it's not just doable, it's one of the easiest things in the game. This game requires you to think and prepare. It's not hard.

[Morthra]

Git gud. I was able to completely clear out the Verdant Chambers without too much issue - the owlbear was probably the hardest part due to its insane BAB.

If you found the vywer statue in womb of lamashu you can use it to bind and distract the monsters.

[For_Science!]

I have tried ten times already to escape.

Sounds like you've tried the same thing, ten times in a row.

There are other escape routes besides climbing the wall, and other skills that help with them. For almost any character, you can find a trick that works. You might need to reduce encumbrance and armor penalties, buff ability scores, think about items that boost skills directly, use summons to draw monsters away from your path, etc. Every potion, scroll, and wand you've ever found becomes a possible tool here (though in some cases, only if you've got ranks in Use Magic Device.)

I enjoyed the challenge of figuring out how the hell to escape this apparently deadly ambush, but I grant that some characters may truly have no feasible way out. But even worst-case, you can reload and come back when you're more powerful. I don't think there's a time limit on this quest.

[Naked Granny]

I think players who don't want failure to be a possibility should be ashamed...

[JODEGAFUN]

Go on story difficult and you can even kill all the stuff alone.
And yes take the neclace in you found in Varnburg (you can triggern an event that some guards will lead you to the city, the neclace is in one of the chest there. and put away all crap stuff which is havy)

[nemovadis]

Sneak (with invisibility it's easier), go up the stairs and avoid the Redcaps, only the last one should prove any trouble, and you can actually flee to the place where you climb down the tree.

[DimensiO]

Its hilarious to me how everyone just overlooks what I've actually written. As if I havent tried these things. I'm not going to write a whole essay explaining every exact detail I did, which routes I've tried, what weight distributions I've managed. Eventually it boils down to having to make two rolls. One for stealth and one for the climb. If both rolls fail, it doesnt matter what I'm doing. But what am I to expect from the steamforums. Eeh...

[Autocthon]

Fun Fact: Invisble does not mean undetectable in Pathfinder.

If you're in light (with decent dex) or no armor you should be able to actually sneak back and around to bypass the climb check. I've done that multiple times.

[Kung Fury]

Lmao everyone has gave you hint or strategies to overcome the problem and gave actual solutions that actually worked for them.
Who give a ♥♥♥♥ about stealth roll if you are hasted, you outrun the ennemies and even if you take some damage you will be able to escape.

You are the one overlooking what people took time to answer to you. But Eh what to expect from the steamforums....

When you enter the map go to the right side and pass the jump check to get on the other side of the hill. Then kill 2 wolves there.

After that go back and enter the castle through the main gate.

Start dialog with nymph and have invisibility potion prepared. When the battle begins go behind the tree to make Hydra lose a sight on you and drink the potion. The Hydra will stop then.

From there you have 3 options:
1. Pass another check and climb the wall. Then use Haste and run till you can jump to the wolf's location.
2. Just run on the wall trying to avoid Redhats. Again you need haste yourself.
3. Summon monsters to distract enemies and sneak by them.

[Wintermist]

And yeah, naturally, unequip the the stuff before climbing to help with the roll :)

[Maay]

Also you can use dimension door to teleport through enemies. It has insane range.

[Kung Fury]

Potion of vanish + scroll of haste that's 1 turn. You can pass by the manticore and the 2 first redcaps. At this point if your invisible break, drink another one and then run again till the end of the wall, you should not have to do anything but escaping to the south east of the map.
