I have 100 enchant with the dual enchant perk, but only have the fire damage perk for offensive enchanting.
I was thinking something along the lines of Fire Damage + Soul Trap (mixed with the Black Star and hundreds of soul gems in my inventory, weapon will always be charged), or possibly Absorb Health + Soul Trap, or Fire Damage + Absorb Health.
Are there any paralysis enchantments? I haven't found one yet, but Absorb Health + Paralyze would be so hilariously dominant.
