When they reached the room and the battle began, Fenna took a moment to see what happened around her before moving. Zell and Barracker seemed to stay closer to James, which meant she could focus on something else. Sil, recognising the skeletons as enemies from the fight when they met, dove onto the back of one of them, using beak and talons to assault the spine and rip out a disc. Once the skeleton fell, she moved on to the next.

Fenna used the blunt end of her spear to hit the skull of the closest skeleton, but it wasn't the target she was going for. The wraiths were an issue and Barracker handled the two closest to him, so she'd deal with the other two. She held her spear with two hands again - a painful reminder of her injured hand, but it wasn't that bad she couldn't fight with it. 

James said something about a phylactery... what was that and what did it look like? She glanced only briefly at the greater wraith, that one had to be dealt with and she had an idea, but she needed a moment to focus and a clear path, she couldn't do that with the lesser wraiths floating around yet. 

When the Lesser Wraith attacked Mackensie, she attacked it from behind and stabbed it in the back. It screeched and turned around, raising a sword to attack, but that left an opening Fenna could use to pierce it again. If she hadn't been able to catch it by surprise, she wouldn't have been able to finish it off that easily. Being busy with MacKensie's wraith, she didn't have time to prepare for the one coming for her or evade the ghostly blade coming down at her back, unless Sil would be fast enough to come to her aid, if she noticed the danger in time.
