I was battling the NPC Swimmer Richard who had a Prinplup. Its moves are Tackle, Pound, Toxic, and Bubble. I use my Bisharp (Dark/Steel) against. I use a move on it, while it attempts to use Toxic. The scenario should be that Toxic fails, because Steel is immune to Poison. However, Toxic ended up succeeding. I think this is a glitch that should be fixed ASAP, as this seems to be a major error.

I think it has something to do with the fact that Bisharp is a Secondary Steel type, not a primary one.

Not sure though.

also has happened with my cursed registeel that i used to have..moltress could never poison it with the toxic move..

It must be a glich. No my escavalier is mainly bug but doesn't get posined. I say it needs to be fix because if its a steel type plainer then there's a problem.

It's probs not a glitch. i don't think that's been programed into the game yet

Yes they can. The game is still very simple as of now, there are only x2 weaknesses, x2 resistances, and no effect bonuses. Posion can poison any type.

Wait it gets posined 1/2 the time? Is that possible?

They can because da man programmed it a little incompletely. Because of that fact, a spiritomb is now effected by close combat

i dont think every pokemon has the ability to not be affect by toxic. is it just golett??

Well it definately doesn't work on Dialga. I did a battle and Mew's toxic did not work on it.
