Shelmet & Karrablast Evolution Method
As settled upon by the design team on two separate occasions, this is the plan for Shelmet and Karrablast:
Shelmet and Karrablast will evolve into Accelgor and Escavalier respectively when traded in multiplayer, as you would expect.
However, in singleplayer, the following series of events will have to transpire for both Pokémon to evolve:
- Use a Link Cable to evolve Shelmet into Accelgor, so long as there is a Karrablast in the party. (Nothing will happen to the Karrablast.)
- Once Shelmet evolves, a new item called the "Shell Helmet" will drop at the player's feet, or be placed into the player's inventory if it is not full.
- Using the Shell Helmet on Karrablast will cause the Shell Helmet to be consumed and Karrablast will evolve into Escavalier
Additionally, the Shell Helmet will be one of the many items that will be equippable by the player (helmet slot) when we add those mechanics in a future update.
The Shell Helmet cannot be crafted, and can only be obtained by evolving a Shelmet. Possible variant textures using NBT for a Shiny & Radiant Shell Helmet could be a fun flex to wear, but that is an entirely optional feature.
