I started The Raptors special slayer task after doing Unwelcome Guests, and I didn't realise I needed a higher slayer level to attack the monsters. I spent a lot of time getting 42 slayer points so I don't want to spend 30 of them on cancelling the task. I kind of feel like I should have been told I couldn't get the task yet, or something. Now I can't train slayer at all, ever.
