Gas masks let you ignore airborne pathogens, and they give you unlimited sprint, but they hinder your vision significantly.

Oh god no not that game

Are you my mummy?

Best comment ever XD

I second that opinion.

Tell a story about a time the GM forgot about a skill, ability, or item you had that came in handy at just the right moment.

Well, last week, I was playing as part of a Fifth Edition game. The game was focused on the encounters storyline, but we were just doing it for fun, not for their system. The group had swollen suddenly over the past few weeks, now totaling at 9 players, so we had been discussing splitting up. One of the newer guys, who had missed a session or two, was playing a ranger. He and I were the only sneaky people in the party, me being an elf with a shortsword and the criminal background.

I did not, however, have a ranged weapon. Thus, when a party member found a +1 bow, and most of the people didn't feel like going for it, I pointed out that I had no ranged, and thus could use it. The ranger wanted it as well, but I put forth that he had a ranged weapon, it was just a 1 point lower bonus.

The argument did not heat up, but his character did decide that he would fistfight me for it. I readily agreed, only to have him throw the first punch, dealing 4 nonlethal to me. Then, it was my turn. I proceeded to pull out several die, and that was when he realized that I was not in fact a rogue. I was a monk.

The ensuing punches took precisely one round to knock him unconscious, leaving me with the bow, and his character flat on his ass, while laughter from the better informed members of the table echoed about the room.

Not the GM per say, but he didn't bother to warn the player, either. So I can't say for sure he didn't forget

...wouldn't the obvious choice have been for the Ranger, as a specialist, to get the magic bow, and give you their old one so you had a ranged option?

I hardly ever find magic items, but skills, spells, and mundane equipment come in handy all the time. My favorite incidence of the GM being surprised would have to be when, in the absence of a rogue, my Ranger used his battleaxe and a pry-knife to open every door and chest, as well as loot all the locks and hinges. Amusingly enough, the axe didn't see much combat use that day, since he also diplomanced the party's way past half the dungeon's encounters (with a little help from the Druid's CHA score.)

Up there! At the top! Everyone vote!

I was playing a Stargate themed pathfinder game when the party got imprisoned in a Goa'uld Ha'tak. I was playing an alchemist and the bad guys took all of our holding pouches and weapons, So we had no handy haversacks or spell component bags or weapons. We managed to make it out because the Gm forgot I had a Robe of Useful Items with a 10 foot portable hole patch still on it that I had looted from a cultist. Luckily I didn't open a hole in the side of the ship that would have opened us up into Hard Vacuum. And that was how I thwarted the Gm.
