Death Strike

You embed your weapon with shadow-wreathed energy that can siphon life force from others to heal your wounds. Make a melee spell attack against a creature within your reach. On a hit, the target takes 1d4 + Your Charisma modifier in necrotic damage, and you regain hit points equal to half the amount of necrotic damage dealt.

• Blood Shield: You receive half of what is healed to you or 1/4 of the necrotic damage, rounded down as temporary health points after being healed. 
• The effects of Blood Shield can occur even when the caster's health is full.
• Blood Shield fades by one temporary point at the start of each caster's turn.
  • Example: If you damage the target by 4 necrotic damage, 2 health points heal you, then receive  1 temporary health point 
• Hitting a target with this attack spell causes much blood to be expelled into a 3ft radius centered on the caster;
  • This gore makes the ground slick and challenging to walk on, causing the caster or any other creature to slip and fall while moving. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d4 for each slot level above 1st.
