See my Dragon Lord achievement guide if you have not already activated the dragon.
You will now have a dragon icon in the top left of your screen. When you are on the map (Not inside a dungeon) you can click
to call forth your dragon and it will breath fire down on the enemies for 200 damage. Easiest way to get 100 kills is to do the following.-At night, 4 skeletons spawn on each side of your base on the 4 different maps. So you can get 32 kills minimum each night.
-Walk over to each skeleton group until you have all 4 grouped up and just guard their attacks with a shield and call your dragon. He will come and kill all of them. Rinse and repeat for each skeleton group.
-You can try to mix in the wolf enemy if you want. This would sometimes net me 1 more kill but often times the wolf would survive...so I found it to be more trouble than it was worth.

You'll first need to awaken your Dragon before you can start killing things with it. See Dragon Lord for more information on how do to that.
Once your Dragon has been awakened, you'll be able to call it down by pressing 
when on the surface/outside. Furry little critters and chickens are not your enemies. They come in peace and will not count towards this trophy. Only things that will actively attack you as you stroll by will count towards this trophy, including the random large animals that appear at night.
You’ll be mostly working on this at night. The only time you'll really be calling your Dragon during the day to help you fight things is if your Castle is under attack by the Undead Horde or if you have a Multiplayer game active and the AI decides to try and fight you. Other than that, there’s no reason to call your Dragon during the daytime.
When it's night, there will be patrols of Skeletons that roam around. Early in the game, it'll be groups of 2. The size will slowly increase as the days go by and you'll eventually find yourself fighting up to 4 at a time. When you come to them, call your Dragon and he will one-shot all skeletons visible on the screen. The large animals most likely won't take just one hit but your Dragon will still do some hefty damage to them so if you hit them a few times before calling your dragon, your Dragon's fire should be able to finish them off. Just make sure you're summoning your Dragon whenever it's cooldown is done and you'll be able to crank this trophy out in a few night's time.
As soon as your Dragon has killed it’s 100th enemy, the trophy will unlock.
