Bonus - The Great Hollow | Walkthrough Dark Souls Guide
Last update: 11 May 2016
In this location you're exposed to the curse. So you might equip a good armor against this ailment (Gold-Hemmed set for example, which can be easily obtained in Demon Ruins).

An entrance to The Great Hollow is located in Blightown swamps. Look for a branch leading up the large tree - warning: the entrance is guarded by leeches. [1] Climb up the branch. [2]
 |  |
Inside you'll find a chest and a wall behind it. Hit it to reveal a secret passage (you'll have to repeat this after a moment). [1] Before you go down, light on the bonfire. [2]
 |  |
Run forwards on the branch, heading down. [1] Go down to the wider walkway. [2]
 |  |
At its other side you can shorten your way and jump down to a lower level. [1] You might be attacked by frogs there. Watch out for their gas - it causes the curse, which takes half of your HP bar! [2]
 |  |
Head down, going from one walkway to another. Near one of them you'll find a ladder - you can use it to go down very fast. [1] Use the next ladder in the middle of your way and go to the level with a floor. Watch out for holes - you can easily fall down and be killed! Another problem is opponents - more black frogs. [2]
Go down onto the next ladder, located in the centre part of this "chamber".

On the "mezzanine" you'll encounter more frogs. Kill them and go down the branch located in the central part of the location. [1] You'll encounter little mushrooms - they are not tough but watch out anyway. [2]
At the very bottom you'll encounter larger mushrooms. You must be very careful there and attack only after enemies' hits. Mushroom-parents are slow but can kill you with one hit and surprise with a double combination of blows.
An alternative method of killing large mushrooms is to retreat to the path up - after several meters mushrooms will lock themselves on the root. So you can kill them now with your bow.

If you do not want to fight with tough mushrooms, bypass them by running to the side corridor. This path leads to Ash Lake. [2]
