Ant-Man Suit

Created by some weird guy who loves ants a little too much, you now have the suit of the legendary adventurer "The Ant-Man".

One of the ten charges can be expended to change the user's size to tiny, huge or gargantuan.

While tiny (you can be in other people's spaces), attack rolls against you are made with disadvantage and you have immunity to fall damage. Additionally, when attacking a creature, any bludgeoning or slashing damage you deal is changed to piercing damage and any perception checks made to see you are made with disadvantage. 

When the user's size is changed to large (10 × 10 × 10) huge (15 × 15 × 15) or gargantuan (to a max of 30 × 30 × 30), they gain a + 2 to their strength score (+1 to the modifier) for every 5 × 5 increase. For every 10 × 10 increase, they gain 5 temporary hitpoints. They also gain resistance to all non-magical, but they can only stay in this form for a number of rounds equal to their proficiency bonus, multiplied by ten and then divided by the amound of 5 × 5 increases (large would not be divided, huge would be divided by two and max gargantuan would be divided by 5)

When you revert to your normal size from large, huge or gargantuan, you gain one level of exhaustion. You also gain an odd, but not detrimental, craving for citrus fruit.

 

The armour also allows the user to communicate and control ants within a mile. You can use an action to command all the ants within the mile to complete a task that is achievable. Multiple different commands can be issued at once, at which point the ants in the mile will split evenly to complete the tasks.

Made from tough but flexible leather, studded leather is reinforced with close-set rivets or spikes.

Notes: Buff, transmutation
