herblore as a lowest lvl... constructions mine. I have many levels above 70, and somehow my combat skills go above 80. But my highest lvl is 84 and lowest is 15, you can tell i don't like construction (lvl 15).
Isn't that why you bring a teleport? I hate it when i'm on a lvl 3 clue scroll, (i am a clue hunter, this is daily) and i get attacked. Of course, i never have many items on, i drop all but the clue and my dds, and i'm fine, but it annoys me like heck.
