In Don't Starve Abigail is summoned by placing the Abigail's Flower on the ground and by killing any Mob near the flower. Wendy's own death is also enough to summon Abigail. However, "murdering" a captured mob creature (Rabbit, Butterfly, Bee) directly from the inventory does not work as a sacrifice.
Mobs engaging each other and causing a mob death near the flower (e.g. Pigs vs Spiders ) can also cause Abigail to spawn. However, if Abigail "dies" and despawns into a flower and mobs die (or Wendy kills something) around the flower after the cooldown period, Abigail will not spawn unless the flower is picked up first and then placed down near a death occurring.
Summoning Abigail drains Sanity by 50 points. When she "dies", she will drop the flower so Wendy can spawn her again after the cooldown period has expired. Note that one hit from the player will kill her and she can often be targeted unexpectedly by the player during battle.
The flower has three stages of blooming. Initially, it will start as a pale, closed flower. Once charged, it becomes a more reddish pink color and is in bloom. In the third stage, when ready for the blood sacrifice, it will levitate slightly above the ground. Abigail's flower does not need to be in the player's inventory to bloom, so it may be left at the player's base in lieu of inventory space while it (re-)charges. Abigail's flower is also visible from the map screen, making it easy to relocate should the player accidentally lose track of it. If the flower somehow falls into the ocean, it will disappear like a normal item and will re-spawn near the player.
In situations where Abigail somehow ends up following a player character other than Wendy (e.g. by completing an Adventure Mode run), Abigail will continue to follow the new character around in Sandbox Mode but will not drop the flower upon dying.
In Don't Starve Together, Abigail can be summoned by using the Abigail's Flower in the inventory without any other condition, and Wendy gains 15 . Wendy can also use the Abigail's flower on Abigail to unsummon her and to lose -15 .
Wendy can ask Abigail to stay close to her or roam more free via Abigail's flower. In Sooth state Abigail follows Wendy and will attack Mobs that either attack Wendy or that Wendy herself attacks. In Rile up state Abigail attacks every Mob close to Wendy, enemy or neutral.
If there is multiple Abigail's Flower at the same time they all behave the same. Flower has 4 blooming stage. The first stage is obtained when Wendy is far from the Abigail's Flower, on the ground or in other player inventory. The second, third and fourth stage are linked to the maximum health of Abigail.
- There is a Forge exclusive profile icon depicting Abigail's Flower. According to the icon's flavor text, the flower is Wendy's only remaining keepsake of Abigail.
- In the animated short Next of Kin, a picture of Abigail's Flower can be seen pinned on a board that connects various people, places and events to Charlie's disappearance.
