World Ender (Aatrox R)

You unleash the dark power within, transforming yourself into a harbinger of death. For the duration, you gain the following effects:

• You grow in size, similar to Enlarge in Enlarge Reduce.
• Your movement speed is doubled.
• Creatures of CR 1 or lower are frightened of you for the spell's duration.
• Your melee weapon attacks deal an additional 2d6 damage of the weapon's type.
• You receive 50% more healing from all sources, rounded down. (e.g. 11 healing becomes 16)
• You have advantage on constitution saves.

If you kill a creature while this spell is active, the duration extends by 1 round. The transformation ends if you are reduced to 0 hit points or if the spell's duration expires.
