These are similar abilities. Regeneration is limited to the mutants themselves, and is usually an unconscious action. Healing is the ability to cause others to heal or regenerate, and is usually under conscious control. Most healers are able to apply that ability to themselves. Note that some healers and regenerators are limited to affecting either wounds or infection/disease only. High-level regenerators are typically only affected by a drug the first time they ingest it, and for a shorter time than a non-regenerator. Some devisor drugs however work better for regenerators than normal drugs,.
