Banned becuase I am taking a week long break from the game do to much work. I can do my work and post here at the same time, but can not do the work and play at the same time.
I was training the other day and this exact thing happened. I ate the salmon and yet no health healed. And if you think it is because the thing I was training on hit the exact amount the food I ate healed no.I know you lose your hitpoints before the number actualy appears but when the number did appear it was a 0.
If you have a decent knowledge of merchanting it will be the quickest with those stats. If you don't have a clue about merchanting then stick with wood cutting.
I'm only responding to the trace metals idea. I like it it would make minning way more intersting. I like most of your idea regarding it including you must have a high enough lvl to recive that ore. The odds would have to be lowered however, ecspecialy for runite. Overall I like it a lot.
