This name is about as descriptive as it gets. Misfit Studios covers more dragons for Savage Worlds.
Ice Dragons have a couple of breath weapon options, the first being a cone of frost that is handled like a typical Savage Worlds cone attack...but the second is a cold fog that utterly blocks all vision in the area. They are also easily baited with warm flesh. In fact, it's probably easier to trick one than to kill one.
The Mountain Dragons is gigantic and scary, spewing hot gravel from its mouth and having a massive treasure hoard. There is a hefty payoff for killing one...but this one will make you work for it.
Sea Dragons are interesting creatures in that they have tempermants as violent as the sea...that is, you can't guarantee what you'll get from one each day. While individual Sea Dragons tend towards malicious or benevolent (adding a modifier to their reaction roll, it is possible than a normally vicious and destructive creature shows up feeling quite helpful.
Swamp Dragons are acid spitting beasts whose scales can somewhat meld into their surroundings. Rather than kill people and creatures around them, they prefer to torment them, getting more joy from inflicting terror and harm rather than outright slaughter.
Another great entry in the line-up, with some obvious D&D inspiration, just tweaked a bit so that these dragons stand out on their own merits.
