Here is my adjustment of the leaked rework to make it spicier.
Passive: Corpse of Swain - When Swain falls to 15% health. Swain will grant the enemy 50G as a reward. A demonic form will take control of Swain granting him immunity to all damage for 3 Seconds. While in this form, damage dealt with Swain is applied as a stack on Swain. Healing dealt to Swain reduces this stack. After 3 seconds are over, Swain will restore 100% of his health. Swain will enter a recuperation mode. Stacks will start to de-stack dealing damage to Swain.
While in Corpse of Swain - Swain's basic attacks deal AP damage and Splash damage. Swains Attack Speed is also reduced.
Q - Wakening: Swain calls down Beatrice (As big as the elemental dragons) who flies in a skill shot. Beatrice will apply Zaunite which deals damage over time. When he reaches the end of the Skill shot, Beatrice will then stop, and move towards Swain slowly. Beatrice will apply another wave of Zaunite and Fire lasers at the target (Which slow) with the highest amount of Zaunite stacks. When Beatrice Arrive at the other side of the skill shot, he will fly back into the air.
W - Seed of Corruption: Swain will mark a target, Ravens will fly to the target applying a Seed of Corruption. The seed of Corruption will deal damage over time. If Swain or Allies can apply X amount of damage, the Seed of Corruption will pop stunning the target and leave a pool of dark energy. Targets who walk over the puddle will be rooted and dealt damage.
E - Torment: Swain throws a bolt of Dark Energy dealing initial damage and applying a stack of Zaunite.
Passive: Champions and Minions. (Excluding monsters) who die to Zaunite will refund mana and CDR to Torment. (Radius bound around Swain)
R - The Culling: Swain will begin performing a Dark Ritual which can be interrupted. Swain will mark an area on the map which he and his allies can see (The area is about 25% of the map). Swain will call forth Beatrice and his Ravens to the area. Once Beatrice arrives, Beatrice and Ravens will be applying a massive amount of Zaunite. Ravens will move inside out from the Radius of the circle. Beatrice will fire lasers at the target with the most amount of Zaunite, or the lowest total. Beatrice will not stop until you leave the Radius. Beatrice can be taken down and will be forced to retreat.
Dargon Master Swain will replace Beatrice with a random elemental Dragon and Ravens will be replaced by small elemental dragonlings.
