Mega Chandelure’s Super Mega Raid Day

On October 31, Mega Chandelure appears in Super Mega Raids, with a better chance of Shiny Chandelure. It can be raised to Super Max Level, the step above Max, which takes its Mega Energy, and it learns Ominous Wind+ while Mega Evolved.

A Global Challenge from 5 p.m. PDT on October 30 to 8 p.m. PDT on October 31 can unlock attack and CP boosts for it from November 2 to 15. A US$4.99 ticket adds up to 14 Raid Passes from Gym Photo Discs, plus extra XP and Stardust from Super Mega Raids.

Part II: Greavard shines and Mega Sableye levels up

Shiny Greavard appears for the first time, alongside Litwick and costumed Rowlet and Gengar. Mega Sableye can also reach Super Max Level for the first time, and it learns Night Shade+ while Mega Evolved.

If you’re working through the GO Pass, don’t let that November 7 deadline sneak up on you.
