I would go for 52 for terrorbird then 67/68 for warped tortoises and bunyips and then after that go for 79 for titans. It might get a little costly though and as for slayer being most cost effective, it really isn't. You should go to waterfiends, its faster and you make money there, although you shouldn't go there until you have flat 85's. Then if you need cash for shards/seconds just go to aviansies for a while. It's a lot faster than slayer.
