Does Storm blade affect all weapons or just polearms and what does it do?
Storm blade affects all weapons. When you melee with a weapon you won’t deal additional damage on each hit but you’ll occasionally proc a secondary ‘storm blade’ hit. If you setup a combat chat log you can see the effect. The attack is generally about 75% of the main hit you’d do with a decent sword at the same level. It appears to proc around 20-30% of the time when maxed.
