Ever wondered if your healing spells and abilities can turn the tide against undead foes in Dungeons & Dragons 5th Edition? It's a question that has puzzled many a party, and the answer might surprise you. Healing in 5e doesn't just mend broken bones and cure diseases; it can indeed damage undead creatures. Let's dive into the mechanics of this unique interaction.

In the world of D&D 5e, healing magic is often used to restore hit points, cure ailments, or remove negative effects. But what about when it comes into contact with the walking dead? The rules, as we'll see, can be somewhat nuanced and require a deeper understanding of the game's mechanics.

Healing Spell Effects
Many healing spells in 5e have phrasing similar to that of the Cure Wounds cantrip: "You knit together these wounds, healing up to 5 hit points...". The keyword here is "heal," not "restore hit points." This small but crucial difference hints at the potential interaction with undead creatures.

Moreover, some healing spells specify that they remove positive energy that undead creatures can't utilize. For instance, the Beacon of Hope spell states: "Any undead within 30 feet of you Autoheal 1d8 hit points." This explicit mention suggests that healing magic has an inherent effect on undead, even if it's not always beneficial to them.
The Undead's Vulnerability to Positive Energy

According to the Monster Manual, many undead creatures are vulnerable to positive energy, which is the lifeforce that animates living beings. This vulnerability is often noted in their stat blocks. When exposed to positive energy, undead typically take extra damage equal to their proficiency bonus.
Healing spells and abilities are among the primary sources of positive energy in 5e. Therefore, casting a healing spell on an undead creature can deal additional damage, as the spell's positive energy harmful to them. This is a nuanced interaction, so let's illustrate with an example.
Calculating the Damage

Let's say you're facing a Zombie, a CR 1/4 creature with a proficiency bonus of +2. You cast Healing Word, a 2nd-level spell that restores 1d4+2 hit points. The zombie would typically heal for 4 hit points (avg), but due to its vulnerability, it instead takes 2 extra radiant damage (from the spell's positive energy) plus 2 more damage for being an undead creature.
So, the final damage dealt to the zombie would be equivalent to the spell's healing output. Not impressive, but potentially useful in a pinch or when fighting multiple undead with ally healers.
Creature Features and Healing Interaction

Certain undead creatures have features or resistances that modify the above interaction in interesting ways. For instance, a Death Knight is resistant to necrotic and radiant damage, potentially rendering the entire concept moot. On the other hand, a Deathlock Wight's ability specifically targets healers, further complicating things.
Therefore, it's essential to understand not just your spells, but also the specifics of your foes. This knowledge could make all the difference in a tough battle.
