Daily Punch 9-8-15 Iron Skin Magic Spell for Shadow of the Demon Lord

I like what I see from Shadow of the Demon Lord.  Let’s build onto what I see.

Iron Skin                                                               Technomancy utility 0

Duration 1 hour                                                                                           

For the duration, your skin becomes as hard as iron.

You reduce all damage you take from weapons by 1 + your level per attack.

Your fists also do 1d3 instead of the normal damage.

If your normal unarmed damage is higher, increase the damage

one step.
