Amagahd! Double post.
Okay. I got a question. Can you wear full mystic at lvl 20 def when it says its 40 def in Rs2?
Mage is usually never profitable unless your training on fire giants and they drop a d med (most unlikely) or something like that. Alching has come the nearest (alching is mainly for mage xp rather than cash) profitable way of maging that is not based on monster loot. But once u start Fire Blast w\ bind. You own basically.

For the range, 75 range will do like 14's or 15's with addy arrows (f2p). Range is alot faster than mage so u can always switch off.
