Hello, I've been grinding in dragon's den with my Cloyster for some days now. I'm the same level, 100, same attack power, same moves being used. I could always 1 shot everything in there with skill link icicle spear.
I could also one shot the golbats with ice shard.
I would never die when grinding because I one-shot them all.
However, now, I fail to kill quagsires in one shot. I fail to kill golbats with ice shard in one shot. There must be a bug here somewhere, i'm literally doing half damage to the pokemon. Either my attack power is down or the wild pokemon's defense is way high. I now die after several mobs because I'm getting hit because I can't OHKO them.
My cloyster has 289 Attack. Please advise.
