I have both bonecrusher and herbicide, as well as the level 95 prayer necklace (forgot the name) and I use all three on practically every single slayer task I get. I also have a cls, rapier + chaotic staff and an eagle eye kiteshield. Those are all what I'd consider to be worth it. If you PK a lot, maul is where you wanna be ;)
see this is exactly where i stand, i have been leveling slayer, all these herbs dropping, all big bones and shit just going on the ground, and i do need the prayer levels, i am pretty much certain i want the bonecrusher, but herbicide, is it really worth it? like 2x xp for a herb drop? better than a kick in the face i suppose. and with the neclace, should i wait till the highest level prayer neclace then buy it? my prayer is currently 85 so it is still a long while away, would i be best to just get the one that does up to big bones?
i know chaotics are great, but in the long run i think it would be better to get these items, only a one off purchases and they can add up
