Unfortunately for the typical warrior, almost all spellweaving spells require a heck of a lot of mana to use. That means that with spellweaving, meditation is almost a requirement. I say almost because there is an exception to my needing meditation policy (as is demonstrated in the template above).
My samurai does use spellweaving for nature's fury and the occasional gift of renewal, but only against one particular creature or champion spawns.
My spellweaving mage, which is from what I've seen, the most common SW template, is my favorite character to play. Since I haven't bought or won many 120 scrolls yet, I do have a lot of 110's and 115s in my template.
Magery 110
Meditation 115
Eval Int 115
SW 120
Resist 110
Wrestling 90, working up to 120 the slow way
The rest of my skills are currently in inscription, since I raised it to 50 to get an undead slayer spellbook.
Now if you have necromancy, you can use lich form, dark wisp familar or wraith form and high damage spells to regain your mana for spellweaving, leaving out the need for meditation. Or you could keep meditation on the template to make truly insane mana regeneration. But my current necro-weaver is:
100 magery
100 meditation
100 EI
100 Necromancy
100 Spirit Speak
100 Spellweaving
100 Resist spells
When I get my scrolls and suit, which will take a while, I'll improve EI, SS and SW while dropping meditation and then run in wraith form most of the time. But I'll need a lot of SDI and LMC to make that work.
