Pokemon-go – Which generation does Pokemon Go base its move type effectiveness on

pokemon-go

Only generation-I Pokemon are available, however it seems that the types which did not exist in Gen-I do exist in Pokemon Go (e.g. Dark type moves).

So I'm wondering which type chart the game is using for move effectiveness.

  1. According to Bulbapedia, in Gen I Bug attacks were super-effective against Poison, but in Gen II-V Bug attacks are not very effective against Poison. What is it in Pokemon Go?

  2. Similarly, in Gen II-V Ghost attacks are not very effective against Steel, but in Gen VI Ghost attacks are normal effective against Steel. Does anyone have a Magnemite, is it Steel type? Does it resist Ghost?

  3. Does STAB exist in this game?

Best Answer

Through testing on the subreddit /r/TheSilphRoad, the answers to 1 and 2 are:

  • It uses a modified 6th Gen chart as evidenced by the Fairy and Steel types.
  • There are no 4x or 0x attacks, so Ground can hit Flying, and Normal can hit Ghost etc.
  • Values have been changed:
    • 2x --> 1.25x
    • 1/2x --> 0.85x

As for 3, Same Type Attack Bonus (STAB) has been found in the game files to be 1.25x aswell.
