Heal is a blue spell component under the Defense tree that instantly restores health points to the recipient.
The spell heals any living thing that its shape comes into contact with instantaneously. The power of the heal is determined by its modifiers -- most obviously, the Healing modifier. The power of the Heal is also affected by the Lunar modifier and the Solar modifier.
Additionally, if the spell comes into contact with undead creatures such as Zombies or Skeletons, they will instead take damage, making it an excellent spell to use offensively for avoiding friendly fire.
Heal has 100% Life affinity.
The materials required for the heal spell can be found in the Arcane Compendium under the components tab and clicking "Heal" from the list, provided you have unlocked that entry. If this entry is unlocked you can see the required items around the component as shown in the image.

Side-note: This is just the required materials for the Heal component itself and does not include the required materials for additional shapes, additional components, or additional modifiers. The materials needed for these can be found in your Spell Recipe book that you collect from the Inscription Table.
- The "heals harm undead" rule was made popular by the iconic tabletop game Dungeons & Dragons. In earlier editions, specific rules allowed heal spells to deal their heal value in damage towards undead creatures. Later editions codified heal spells as discharging "positive energy," akin to "life force" in most other settings. Since undead were supposed to be constructed and/or animated from negative energy, the two magical forces are said to cancel one another out.
