I was thinking of going on an 85 slayer spree (along with everyone else in runescape :?). I was curious if it was worth it to use lunar magicks spellbook so I can use the "Contact NPC" spell, keeping in mind I won't be able to use the traditional teleports. I do have a lectern to make all available tele tablets, if that plays into the equation. Thanks in advance for the advice!

I find contact npc for slayer work out great. And instead of making tele tabs to every other place I suggest using house tele tabs and portals to tele everywhere. Getting new tasks or switching them aren't as annoying because of it too.

Contact NPC is the most efficient way to do it, because you can go directly to the next monster. Plus, you get a ton of free sand every day from Bert without much trouble.

Thanks for the advice, I'll use home tele tablets and lunar magicks.
