I think with the addition of some rares with the latest holiday drop events, it would be a perfect opportunity to add clue scrolls to the server. Even if you had no chance of getting p-hats, santas, masks, etc. it would still be worth it to me to do them not only for the break away from the grind (something new) but you could add items that would make it worth it like the exp elixers as the rares. I understand how getting p-hats and masks and what not would mess with the 'rares' economy, but i think you could add items that are just as valuable.. I know trimmed armor sets were a huge deal with clue scrolls first came out but i think you could add things that would get players just as excited about getting. some of my suggestions for items obtained by clue scrolls are listed below. Some may seem weird, but after playing in this server I noticed that there are a few mundane items that are actually very time consuming to obtain, like vials.. feathers... what not.. Take a look.

Sorry to those who read this and think some of the drops are retarded or too much? this is just a very crude list of stuff that kind of just popped into my head, its more to get an idea across. I always thought clue scrolls were very fun and if it is possible to add I think the server would benefit in the same way adding the slayer skill would.

Those who say pvp will be ruined by adding slayer and other things... I don't think pvp will be going anywhere, its already very popular on this server and I honestly dont think anything will change that. Adding these skills and activities will just give the players who dislike pvping more options.
