The Military Police

At level 3, you have joined the Military Police and have dedicated your life to serving the king. Because of this, you have instant contacts throughout the Royal Government and Military. You can learn the whereabouts of any important people in the government if you spend an hour asking around any military installation. You also have full access to classified information in the government, as well as first class gear and equipment. Because of this, you do not need to do weekly maintenance on your gear and it will not fail unless excessively damaged.

When you reach level 9, your defensive capabilities go unmatched. When a creature makes a melee weapon attack on you, and if you can see them and you are holding two Titan piercing swords (or two loaded anit- personal guns later), you can use your reaction to gain a bonus to AC equal to your Constitution modifier for the attack and impose an opportunity attack on the creature if it misses. Later, if you choose the Non-shifter feature at level 18, you can do the same if you have to guns equipped.

When you reach level 13, your developments in Grappling Gear flight technology have reached their limits. You can stay flying for double the charges of what it normally would be.  Your flying speed also increases to 90 feet.

At level 18, you have either designed or received from your superiors guns that are designed to work in tangent with your 3DM gear. You now have 2 sets of triggers: one for swords, and one for guns. You can switch which triggers you are using as a bonus action. The gun triggers can connect to barrels that act as shotguns. You can connect these barrels as a bonus action, and fire one of them as an attack. Make a ranged attack roll. On a hit, the target takes 4d8 piercing damage. Anyone within 5 feet of the target also takes an additional 2d8 piercing damage (including the target). Once fired, the guns are spent, and you can detach the barrels as a free action. You can store up to 5 additional barrels on each of your thighs.

If you run out, you can create more by spending 10 gp per barrel and 30 minutes crafting it, or by getting more at a military center.
At this level, you have also received or crafted custom 3DM armor that features a lightweight metal breastplate and arm and shoulder guards. When you wear this armor, your AC is 14 + your Dexterity modifier.
