Over 60 sets of dialogue typed out, that was fun... Another quest down though.
Those three items (Slayer helms being added back in the very beginning of 08) only affect gameplay in the aspect that they IMPROVE Slayer, by making it more interesting and giving you something to work toward besides gaining levels. I'm sorry that you're one of those sorts of people that can't consider something oldschool if an item that only affects a skill is added, that's past 07. If you play RS07, you'll be one of the people to hold it back and eventually lead to it's downfall (lack of any updates due to mindsets like yourself that vote no to EVERYTHING), because anything past 07 instantly becomes terrible because it wasn't added back at that time, regardless of what the content itself is and does.
Complaining about rocks, really? As for Mandrith, he could be replaced by anyone (if you'd like to get technical, BH was released in 07, which makes him an NPC from the 07 era). If anyone besides you SERIOUSLY has a problem with him, I'll change him to something else. The clue scrolls (look the same as every other clue scroll in RS?) stop players from being able to camp monsters for an indefinite amount of time because they don't stack and have to be exchanged at a NPC to receive the money. Considering my server has one of the best economies out of some of the top private servers, I think this change will not only maintain that, but improve it from the previous system.
