Wands are one-handed mace class weapons, so Mace Mastery applies when equipped by Barbarian.
Normal, superior, magic, rare and crafted quality wands can spawn with up to three +(1-3) skill bonuses to individual Necromancer skills (Poison Dagger is normally an exception).
Wand with magic level have affix level (Alvl) = item level (Ilvl) + magic level
All have 100 Strength bonus when calculating attack damage, so +% Damage = Strength
