Creatures introduces players to three new monstrosities to unleash upon any force foolish enough to stand in their way. Two of these figures are variant forms of the promotional creatures that appeared previously.
Sharing a forest home with the Wood Wyvern is the Wood Giant. Towering over his foes, the Wood Giant is able to defend both allies and lair by hurling massive logs! This devastating ranged attack must come from tiles that contain a forest, but the giant isn’t afraid to leave his home to crush invading forces.
A mighty warrior was once tasked with removing a powerful creature from the land. He journeyed far until he reached the creature’s lair. He shot arrows into the cave, hoping to draw the monster out. As the creature ventured forth, he got his first glimpse of this powerful monster. The powerful body, the sinuous movement, the multiple heads... multiple heads? As the warrior attacked the beast, he was able to sever one of these heads. Much to his horror, the head not only grew back, it grew back alongside another head! This creature is the deadly Hydra! Now you can field the might of this mythic monster, and as the creature is wounded is gets far stronger. Every head removed is a new head added, and each head is able to launch its own attack!
Our final creature is the most magical of all. Brought forth from the power of the Magic Vortex, the Rock Elemental is able to appear almost anywhere on the battlefield! This powerful ability, combined with the sheer strength of this creature, can be truly devastating. As this creature can strike without warning, the enemy will be forced to guard his movement, keeping the possible angles of attack right where he wants them.
