Cave Crawling Dragon Age II Guide
Last update: 11 May 2016
The quest giver: Jansen [The Bone Pit]
Step 1: Talk to Jansen
After returning from the Deep Roads and completing the secondary quest Inside Job, go to the [Bone Pit] location. Approach a group of miners standing outside the mine #1, and a conversation scene with Jansen will automatically start (M31, 7). During the conversation you'll find that the mine is occupied by spiders #2. Jansen will of course ask for your help in eliminating them.
Step 2: Eliminate the spiders
Now you can go north and use a passage leading to the [Bone Pit - Bone Pit Mines] location #1 (M31, 4). Once you're inside the caverns (M32, 1) do not go to the main cave, because all the spiders are there (M32, 8). Instead of that order you party members to go up the stairs and be ready #2.
If spiders didn't follow you, use one of your party members to get their attention. Now return upstairs and attack the spiders #1. You'll have to fight giant spiders and poisonous spiders so watch out #2 and heal your party members if necessary.
Note that the queen spider, because of her size, didn't manage to get upstairs. So attack her only after eliminating all normal spiders #1. Do not rush toward main cave during the battle if possible. Go there only after killing the Queen spider. Prepare to fight a new group of monsters #2.
During this battle you have to watch out for poisonous spiders even more #1 and that's because there are plenty of them. Fight until you get information about elimination of all spiders. Now you can return to the [Bone Pit] location and tell Jansen good news #2 (M31, 7).
