A friend of mine currently has 120 magery (real skill), which he says helps him produce slayer spell books. He wants to take taming up to 120, which would require bringing his real magery skill down to 100. He has a +20 magery crystal ring to offset the loss in magery. However he isn't certain if lowering his real skill will adversely impact his ability to produce slayer books. Does anyone know the answer? Thanks in advance.
