As a bonus action you can expend a charge of your wild shape to take on the power of the natural world around you, channeling the wrath of nature into your abilities. While in this form, jagged icy rain begins to pour down around you in a 30ft radius, each droplet as focused and as sharp as high pressure water, and jagged, flowing water envelops your body like flexible armor. You gain downpour charges equal to your wisdom modifier, and can have a max of twice your wisdom modifier. Downpour charges can be spent any time you would be able to use an action or reaction. Although you have much more control over the wrath of the nature around you, it is impossible to truly tame the raw power it has to offer. Should you be hit with a melee attack while in this form, the attack is considered to be an automatic critical hit, ignoring any critical hit damage immunity you might have. Whenever you deal damage, you gain a charge for every 25 points of damage dealt, and can expend charges in the following way. At the start of combat your charges become 0. Should you start your turn under a storm or rain (not created from this ability) you gain one charge.

Down Pour: At the start of your turn you may expend any amount of charges (minimum 1) to cause the jagged rain around you to grow heavier and sharper, more volatile. When you activate this effect, yourself and creatures of your choice in the radius must make a strength saving throw equal to your spell save dc. On a fail any creatures flying lose their ability to fly or hover until the end of your next turn, falling to the ground taking 5d8 bludgeoning for every 10ft they fall, and take magical piercing damage equal to 3 times the amount of charges spent in d8's. On a success, they take magical piercing damage equal to 6 times the amount of charges spent in d8's. This damage does not count as being dealt by you.

Thorns Armour: You may expend 5 charges to cause the thorns around you to grow sharper and longer, protecting yourself from those who wish to strike at you. Whenever a creature hits you with an attack, they take an amount of d12's in magical piercing damage equal to the amount of charges you have, as your thorn armour strikes back, or double that amount on a critical hit. This effect lasts until the end of combat.

This form lasts however long your wildshape would last. When it ends, your charges become zero.
