Illumise punches above its weight class thanks to Prankster. It gives priority to its status moves, which is enough to make up for stats that don't impress on their own. Only weak to Fire, Flying, and Rock. Known as the Firefly Pokemon.
Nothing fancy in Illumise's spread. It leans special with Sp. Def out front. And you'll get 1 Speed EV per KO for it. Follows a standard growth curve.
Illumise attracts a swarm of Volbeat using a sweet fragrance. Once the Volbeat have gathered, this Pokémon leads the lit-up swarm in drawing geometric designs on the canvas of the night sky.
Illumise leads a flight of illuminated Volbeat to draw signs in the night sky. This Pokémon is said to earn greater respect from its peers by composing more complex designs in the sky.
Illumise Weakness
AvgType-wise, Illumise takes extra damage from Fire, Flying, and Rock. With 65 HP and balanced defenses, Illumise can afford to eat a neutral hit or two.
What you see is what you get. Illumise sits outside any evolution chain, so focus on the egg moves and no compatible partners from two egg groups. Eggs are quick to hatch.
How to Evolve
Breed Illumise from the Bug and Humanshape egg groups. Pass egg moves like Baton Pass, Bug Buzz, Captivate and 5 more to offspring.
Focus Sash buys the setup turn. Illumise clicks Growth, then starts cleaning with Thunder Wave and the remaining moves. Timid nature with max Sp. Atk and Speed EVs makes sure nothing tanks a boosted hit comfortably.

Illumise gets Prankster, Oblivious, and Tinted Lens. But Prankster is the one that matters — it's the centerpiece of every viable set. Build around that.
