Miracle Heal is a must-have medical agent for Creatures 3 and Docking Station. When activated, this agent heals any or all creatures in your ship of any illness. This agent was created by Clucky and is available with lots of other agents at The High Tech Hand.
Notes: According to a post made on the Gameware Forums, this medical agent will also inject life into your creature too.
It's available at Creatures Caves.
