Mega Steelix in Mega Raids was a Pokémon GO raid event with 1 raid boss. Here's what's actually worth your time, which bonuses to stack, and whether it's worth clearing your schedule for.
What to prioritise
None of the featured Pokémon are meta-defining for PvP or raids, so treat this one as a relaxed collection and shiny-hunting window rather than a build-your-team event.
Shiny hunting
There are 2 shinies available during this event. Boosted spawn events are among the best shiny-hunting windows in the game, so tap everything you can and keep your Poké Ball stock topped up.
Is it worth your time?
Optional, but nice for collectors. Nothing here is essential for your competitive roster, but the shiny odds and featured spawns make it a pleasant, low-pressure window. Note: this event has already ended — it's kept here for reference and for when it returns.
