Septic Strike

Your strikes are septic; through honing the power of disease, you have gained the ability to harness your septic nature in combat, granting you the following benefits:

• You gain resistance to necrotic and poison damage, but you also gain vulnerability to radiant damage.
• You take half damage when attacked by unarmed undead.
• Three times per short rest, you can convert half of the damage you do from an unarmed strike into necrotic damage.
• You can instantaneously cause plants smaller than two feet in all dimensions to wilt on touch.
