Crimson Samurai

The Crimson Samurai were created and trained by the Shadow Assasin ranks to crush the Origami Monarchs. Their Petal magic revolves around explosions, the petals flying and blowing up to deal excrutiating damage, especially to the paper weapons and armor of the Origami ranks. They decimated the front lines and took the Entaiyan capital within days.

Burning Petal Whip

When you choose this archetype at 3rd level, you may spend an action to summon a petal whip. Petals appear out of thin air, linking together in a long chain that begins to burn. It hardens to the strength of steel, red petals twisting to form barbed spikes. The new whip deals 1d6 + 2 damage, and when it hits, three small explosions erupt up the chain, each dealing 1d4 damage in a small radius. 

Explosive Bloom Armor

Beginning at 7th level, as an action you can summon armor with your magic. Glowing red petals wrap themselves around you to form scaly Samurai armor. While wearing the armor, your AC is 18, and you gain +1 Strength. In addition, whenever an attack made on you misses on a roll lower than your AC minus your Dexterity modifier, an explosion ricochets towards them and deals 1d6 + 2 damage. 

Explosive Latching Scales

Beginning at level 15, while you are in your Explosive Bloom Armor form, you may use a bonus action on your turn to shoot petals off of your bottom, three at a time. They latch on to any creatures of your choice that you can see. You can place one on three different ones, three on one, or two on one and one on another. Using an action, these petals can be detonated, dealing 1d8 + 2 bludgeoning damage each, and knocking the victim or victims prone. 

Consentrated Crimson Storm

Beginning at 20th level, as an action on your turn, you can cause petals to explode towards an enemy in a concentrated blast. It deals 4d12 damage to each enemy in the path you concentrate it on, and each enemy it hits gets four explosive petals attached to it, which can all be detonated at once with an action dealing 1d8 + 2 bludgeoning damage each to their victims and knocking them prone.
