After she had swam into the medium-depth (not too deep) she took another breath and dived under. She was engulfed in another plant. She almost rolled her eyes, if she hadn't been terrified! She looked at the plant - it looked black but she was sure it was green. It was probably a shadow of something. She racked her brain to try and remember something, some spell or technique to use when plants try to drag you under. It wasn't hurting her at all, and she didn't want to harm it with a spell that shouldn't be used, so she tried to remain calm. Maybe that was the trick? She cast "Lumos" to get a better look at the plant, and as soon as she did that it released her. She wasn't sure if it was the light from lumos or the relaxing which had done it. Probably the relaxing... it wasn't as if it was fire or... Devil's Snare.

She cast "Nox" because she didn't want to disturb any of the life under water. She went for another swim around, trying to look for a chest near her. As soon as she started swimming, she started panicking. She hadn't taken a breath. She came back up and gasped to catch her breath. A moment later, she took another bit breath and dived under.
