After defeating The Cultivator on Cultivator Island, you will gain access to the Vine Copse. There, you can modify familiars or vehicles to gain additional powers or stats on your familiar or vehicle

Almost all familiars can be modified. The only exception is the Exo Fighter with pilot.

Most vehicles cannot be modified, the only ones who can are those based on living creatures: Wyrm Queen, Golemech, Adult Dragon, Elder Dragon, Mecha Dragon, Dragon Ship, Mecha Dragon Ship, Dragon Fighter, Dragon Bomber, Dragon Cruiser, Dragomech, and Megolemech. The Dragomech, Golemech, Megolemech, Wyrm Queen, Adult Dragon, Elder Dragon and Mecha Dragon Ship can be modified directly from your inventory.

At the Talon Copse, you can modify any equippable item. The only exceptions are items that can change their elements and items that are ranged weapons. For example, the Mecha Wyrm Helm cannot be modified, as one of its features is shooting a ranged laser.

An item or vehicle can only have 1 modifier at a time.
