Let's Play NWN2: Storm of Zehir #62: Fixing a Hole

We travel back to the city of Neverwinter and speak with Akila in the Thayan Enclave, who has completed his research on the arcane nexuses and discovered that the source is coming from two locations: one in Chult and the other on the Sword Coast. He pinpoints the location in Chult and marks it on our map, and we travel there despite some random monster battles. We discover a foreign temple in a valley, and inside is a Champion of Shade, an undead spirit of the Netherese Empire. Although we drop his hit points to zero, we can't defeat him as a purple ray comes out of a portal behind him. Sending Ribsmasher into the portal, he discovers a Netherese Arcanist whom he quickly defeats, allowing for the defeat of the Champion. Walking out of the door on the other side of the portal reveals we are on the Sword Coast again, this time in an area we couldn't get to before. We ford a stream and find a forgotten crypt, inside of which are many undead, including shadows, mummies, and a death knight. Also inside are many sarcophagi that are trapped, and we are nearly killed when one goes off.
