Terrain Shift

You change the terrain in an area up to 400 square feet. Sound, smell, even feel (including temperature) are like that of some other sort of terrain. The terrain's general shape remains the same, however. Depending on the change certain things could be more altered such as water sources freezing, thawing, or drying out depending on the new terrain.

This terrain becomes your favored terrain, and moreover it becomes your lair. While in this terrain you have advantage on attack rolls and advantage on saving throws.

Your lair also allows you to take special actions, such as:

• As a bonus action you can create three duplicates of yourself within 30 ft of you. This duplicates cannot attack and have an AC equal to 10+Spell Modifier. If they are within five feet of an enemy attacking you, you can roll a d20 to determine if the attack hits you or one of the duplicates instead. If you have three duplicates, you must roll a 6 or higher to change the attack’s target to a duplicate. With two duplicates, you must roll an 8 or higher. With one duplicate, you must roll an 11 or higher. These duplicates disappear at the beginning of your next turn.
• If you or an ally are targeted by an attack while in your lair, you can use a reaction to shift the terrain to lessen the damage of the incoming attack. The shift in the terrain gives them resistance to the incoming damage and counts as 2/3 cover.
• Your lair is as much a weapon as it is a shield, you can make a ranged spell attack as a bonus action against an enemy of your choice within your terrain. The spell attack deal 4d10 bludgeoning, piercing, or slashing (Chosen before the attack is rolled) on a hit and the spell has a range of 60 ft originating from any point in your lair.

You can only use each of these once per round.
