The free autoprayer bot from rsbots.net does that.
and it worked last time I tried it.. but it's been a while.
I don't see how bone burying could have changed though xD
http://www.rsbots.net/bots/AutoPrayer/ is the link for it..
or you can just add the auth: 92xz77B7P16KRPCU9 to your client.. it's a free bot.
Because they are stackable.auto clicker and just spam them lol
