Shield Wall

You hold your shield in front of you and duck behind it, making the shield like a wall. While behind the shield wall you cannot move, however any attacks that target you must first get past the shield wall. This increases your Physical and Magical Armor by 1d4, making it harder to hit you. If any of your allies use this with you and are next to you, a more secure wall is formed further increasing Physical and Magical armor by 1 for everyone involved. 

Guard

This skill allows you to defend an ally from attack. You use this skill when a nearby ally, one that you can reach with one movement action, is being attacked. 

Dwarven Tuck

When in defensive stance, the dwarf can sacrifice his or her movement action for the next round and pull him or herself in even further, tucking into the dwarf's armor. This will increase the dwarf's Armor Defense and Armor Spirit by 20% for the duration of the defensive round.
