You can obtain Gallade’s Mega Stone (Galladite) by talking to Professor Cozmo in his house in Fallarbor Town. You’ll find his house located southwest of the town’s Pokémon Center.
However, he will only give you the Mega Stone after you have completed the Delta Episode in the post-game.
Galladite Location (Step-by-Step)
After you finish the Delta Episode you can head back to Fallarbor Town to grab the Galladite from Professor Cozmo in his house.
So to get started, first complete the Delta Episode, and then fly back to Fallarbor Town.
Step 1: Begin by heading southwest from the Fallarbor Town Pokémon Center.
Step 2: After passing the town sign, enter the house located immediately to the left of the sign. You should see an NPC dressed in brown standing next to this house as well.
Step 3: Inside the house, talk to Professor Cozmo and he’ll give you the Galladite.
Is Mega Gallade Worth Using?
Mega Gallade appears promising on paper, but it struggles to compete with common threats you might encounter. Notably, it has a hard time dealing with prevalent Fairy- and Psychic-types.
Nonetheless, with access to Swords Dance and powerful STAB moves, it can still be quite effective in its role as a physical sweeper (given the right circumstances).
Tip: Mega Gallade’s new ability is Inner Focus, which prevents the user from flinching.
If you’re considering using Mega Gallade on your team then here are a few pros & cons to help you decide:
- Excellent stats for a physical sweeper. With a base Attack of 165 and Speed of 110, Mega Gallade is a natural fit for the sweeper role.
- Good bulk for a Swords Dance user. Mega Gallade can withstand some attacks while setting up Swords Dance, which makes it a decent wallbreaker as well.
- Immunity to Fake Out. Mega Gallade’s ability means it will never flinch to the move Fake Out. It can also hold up against other flinching moves like Mega Kangaskhan’s Bite and Togekiss’ Air Slash.
- Access to a wide movepool. Strong STAB attacks like Close Combat and Zen Headbutt are complemented by coverage moves such as Ice Punch, Knock Off, and Shadow Sneak.
- Struggles against Psychic types. Psychic types resist both of Gallade’s STAB moves, making Knock Off almost essential for coverage.
- Walled by Mega Sableye. The commonly used Mega Sableye hard counters Mega Gallade, as its typing makes it immune to both of Mega Gallade’s STAB moves. It can also cripple Mega Gallade with Will-O-Wisp.
