Your Adventurer's Atlas improves, gaining the following benefits.
Safe Haven
When a map holder would be reduced to 0 Hit Points but not killed outright, that creature can destroy its map. The creature's Hit Points instead change to a number equal to twice your Artificer level, and the creature is teleported to an unoccupied space within 5 feet of you or another map holder of its choice.
Unerring Path
If you are one of the map holders for your Adventurer's Atlas, you can cast Find the Path without expending a spell slot, without preparing the spell, and without needing spell components. Once you use this benefit, you can't use it again until you finish a Long Rest.
