So, I suppose planning something that catches the DM off guard sounds like a fun game.

That reminds me of a story from one of the campaigns I was a player in.

We were trying to track down one of the other player's in game father, who had been kidnapped by genocidal elves. In the process, we scryed on him, but realized that, with a combination of a few magical traps that lasted a day per casting, if we tried to teleport to him, we would end up in the crater of an active volcano.

That was when we came up with the wonderful idea of: well, if they used this trap, they had to come to the volcano every day to cast it.

We then teleported directly using the trap and sat above the crater until the poor wizard showed his face.

Priceless when we casted dispel magic on his fly spell.

On the subject of volcanos, I one was playing a character so crazy (and with motivations so alien to the other characters) that when I was away for a session they had to roll randomly to determine what I would do. This lead to my character choosing to jump into a volcano. Of course, the DM was flabbergasted. Especially because, unbeknownst to anyone but him, the volcano was a mythical site of power (thus why the dungeon was built into it etc.) and jumping into it actually granted anyone fool enough to do it a wide variety of minor powers. Suffice to say, when I came back the next week, I was certainly not disappointed. Roleplaying at its finest!

Of course there's always the destroy the environment stories. I once was able to circumvent nearly an entire adventure's worth of content by using searing hands on the ship we were attacking. It turns out sails are flammable and water is kept below decks. I have to say, killing approximately 20 enemy combatants with a first level spell was pretty awesome feeling even if it did take 15 minutes for the fire to consume the ship (and circumvent the plot rather handily).

Most recently, the DM sent us in to "contain" some unruly kobold mine slaves. Both our LG cleric and our LE sorcerer (myself) agreed, the kobolds should be working for fair wages (never mind that our sorcerer just wanted to use them to kill the owner and claim the deed to the mine and the corresponding local monopoly for himself). Watching the DM's face as he heard two party members who had spent the entire campaign trying to get each other killed (okay, my cleric friend was trying to reform me, not kill me, but only because he was a wimp) both argue for the fair labor rights of kobolds was pretty funny.

In a recent session we were fighting a creature who was attacking us through this extra dimensional portal in the ground. I decided to jump in, even though I had no idea where I would end up. I think he was a little surprised.

Is there something wrong with me when I can read Raxon's post just fine?

No, most of us are wired to register words so long as most of the right letters are there.

Sorry Raxon, but Lolly, Lolly, and Lolly disagree.

What was that, GM? "I'm taking him down if it's the last thing I do?"

Luke is a master of Batman Gambit.

No, I'm not linking to it.

You fiend.

you think he plans these things?....

In the most recent session with my 4e group my character was caught in the middle of a war and basically handed command of the entire army because the actual commander had lost morale. My answer to that was to first throw a diplomacy check or two to encourage the commander to get her ass in gear. Then I went commando, marching through the city using extraordinary intimidate to force the surrender or fleeing of every enemy I met without ever actually attacking. Finally I reached the king and queen of neverwinter (which we were invading). they were more than twice my level. another 2 PCs were fighting them too and frankly they were going to die. My character rode down on an airship landed next to them and demanded they surrender, despite the fact that they would have killed all of us if they kept fighting they surrendered because I had demoralized most of their generals and their castle had just collapsed from the airship attack rolled an 19. My GM just looked at me in shock. Somehow I had managed to start, wage, and then end a war with one of the most powerful cities in the world while staying on the front lines without ever making a single attack roll.

Nice. I feel like the intimidation side of diplomacy gets overlooked by a lot of my players.

My DnD group went slightly off the rails due to an incident I had caused with Fritiz the gnome (With mad bomber personality included). Large army was coming as we were going to be captured... but Fritiz lit his massive explosive bomb and launched it off an ejector seat he made towards the army.
Then it blew up the vanguard which set of the explosives in the armory near them which then grew big enough to set off the explosives they had... It quickly became fourth of July leaving the big bad alive but heavily injured with our party outnumbering him with full health. Needless to say we then proceeded to charging the enemy. That ended with a temporary paralyses spell that allowed us to steal his weapon in mid-combat leaving him to fight us unarmed.

To this day the DM made sure that my gnome wasn't allowed to build a bomb bigger than himself even if he couldn't carry it much less move it.
