OK. I got a little behind on this thing and I need to catch up so I will do so in this post. Besides, some of these questions are best suited for quick answers anyway.
Day 11 - Favorite Adventure You Have Ran
My favorite module ever is probably B2 The Keep on the Borderlands. It was included with the Basic rules and I used it several times to introduce people to the game so I have ran it more than any other adventure.
Day 12 - Favorite Dungeon Type/Location
Give me the sprawling megadungeon any day.
Day 13 - Favorite Trap/Puzzle
I am just not a trap guy. I have used and will continue to use traps that are detailed in products such as the Grimtooth's line of products but I do not try to devise my own traps. It is just not my thing.
Day 14 - Favorite NPC
I assume this means a recurring NPC from my campaigns and I do not have one. I prefer to not have recurring NPCs showing up time and time again. Maybe a few show up until they are eventually vanquished but there is no villain that escapes time and time again attempt to defeat the group yet again.
I am caught up on the 30 Days of D&D Challenge now. I probably will not be very productive on the next run of questions just because I do not think the favorite monster needed to be split up into a weeks worth of posts. That is just me, though.
