How much fire spell dmg and pirce can u get by blessing an circlet for example? is it only 8% dmg and 5 pirce? im still trying to craft some good eerie crafts with decent rolls on pirce on the gloves but its hard
Circlets are under the "Helms" category, so they can roll up to 10 pierce before shrine. Shrine is 5 pierce so with bless that's 20 pierce possible on circlet.
Same for fsd, 15 max before shrine + 8% craft + 8% bless = 31% fsd possible. You likely won't ever reach these numbers so just take the best roll you can get.
This guide needs a little overhaul with patch 1.7 as the bits about synergy aren't accurate anymore. Same for the skill Familiar. See this page for updated info: https://docs.median-xl.com/doc/concepts/spellfocus
Energy and Spell Focus are NOT linked anymore (unlike energy & energy factor before), so you can't get away with lower SF by pumping 5-6k energy. In short: you should get Spell Focus as close to 1000 as you can. Put points in energy until you reach 2000, then check with your mana hungry spells to see if you still need more to sustain and raise energy accordingly. When you feel comfortable enough, put the rest in vitality.
