If All you wanna do is kill sea serps.
Then all you basically need is enough magery to recall.
And a nice pair of vollems
For tougher stuff, you might wanna use a template like basara's.
A badass fisherman with a GD, would probberly also work.
My fisherman template is.
120 magery
120 eval
120 medi
120 resist
120 wrestling
xxx fishing/scribe (I swap as needed)
I use a pair of vollems..
All guard me And fish away.
