Rather than watch me frothing at the mouth, just read no. 10 below:
Arwink's Top Ten Reasons Why Kobolds Are Going To Take Over From Dragons In The Title of 4th ED.
1. The image change started in 3e the 3e books, and Kobolds look better in spikes and chains than dragons do.
2. Sorcerors have the blood of dragons in the veins, and kobolds are the sorcerers that most enthusiastically repeat this claim. Innocent flavor text, or is Wizards softening us up for the change?
3. Kobolds taste of oil and cabbage, while dragons are akin to chicken. Who are you hunting for dinner?
4. The years of skill the DM community has put into mastering the use of kobold has taught us nothing about dragons. They're to small to fit in tight passage ways, claws are a pain when setting traps, and dragons can't stand each other long enough to deal with team-work.
5. Everyone wants to be called a Dragonslayer, cause dragons have lots of hit points and fearsome attacks. Sooner or later, even the great wyrms will be hunted to extinction. (This is a clever peice of campaigning on the kobolds part, because it also causes everyone to underestimate creatures with no natural weapons and a piddly half a hit die.)
6. Kobolds and dragons crossbreed well, creating one of the most dangerous creatures known in any plane. These half-kobold/half dragon legions will wipe out dragons as we know them, claim the leadership of the kobold race and enjoy all the preveliges of both races.
7. Dragonlances are back boys and girls, and they are coming to a 3e game near you. Kobold lances are yet to be discovered.
8. Kobold sor8/rog5/assasin7. He should be able to take out the younger wyrms, and he'll move onto the older ones when the epic rules come out. Some may call it cheating and unfair, but the kobolds call it an investment in the future.
9. Kobolds have less shin than dragons, and are therefor less prone to nose bleeds.
10. Many DM's consider it a mark of pride to kill a party of 10th level characters with a well played kobold clan, yet few seem proud when they manage the same feat with a single dragon.
(This is, of course, a complete miscomprehension on the DM's part - players prepare for months before fighting a dragon, yet they'll blithely walk through trap after trap in a kobolds lair until their opponents have more hit points. Killing a party of overconfident PC's is easy, killing them once they've buffed up with magic is hard. More DM should take pride in the skill with which they run dragons, and realise that the innocent-looking kobolds are truly character death incarnate).
Somedays I think B.A.D.D needs a sub-branch - Bothered About Killer Kobolds
) but simply got the better of? Post stories if they are good as well heh. I've always felt that kobolds tend to get the shaft. I did once make a 10th level party hand over a magic item to escape a trap the kobolds set. Unfortunately upon being set free, they 'fought' their way out.
