It is very difficult to beat full Tal's for all the great mods on it.
If we are talking uniques, I would list them as follows:
1. Death's Fathom
3. Eschuta's Temper
4. The Oculus
From my list, I value the damage of 1. over resists. If you don't have 1., then I value resists over damage. In SC, Occy is 4. and Wizzy is 5. In HC, Wizzy is 4. and Occy is thrown out with the garbage.
To answer your question, Wizzy is a great weapon, but if you can get the resists and FCR elsewhere, then Occy is better (provided it is SC).
thx a lot im fairly new so this character will be playin with pretty much what she gets as far as weapons go. I need resists and FCR because i dont have great equimpent so i guess I'll use my spike. thx again for your input
