Ah yes, beautiful, scenic Lake Ken-I-Po... an unfortunate name for a wonderful place. Chaotic is filled with unique and interesting Locations that act as the "Where" part of each turn in the game.
Both players get 10 Location cards in separate little deck on the side of the table. At the beginning of every turn, the Active player (as in the player whose turn it is) flips over the top card of their location deck and that new Location replaces the previous one. All Location effects are active as soon as the Location is revealed, before combat begins.
Initiative
One of the most important things Locations do is decide who gets to throw the first attack in a fight. Initiative tells you who gets to go first. Lake Ken-I-Po, for example, tell you to compare the 2 engaged Creatures' Power stat, and the Creature with the higher Power gets to move first.Mipedim Lounge asks you to look for a Creature Ability, Invisibility. So a creature with Invisibility gets to move first! When you tie with your opponent's Creature for Initiative, the Active Player wins Initiative.
Mirage
Mirage is a pretty unique Location ability. When a Location with Mirage is the Active Location, the Mirage ability is NOT used. Once the turn where that Location was Active is over, the Mirage Location is placed on an empty space on the field. If a fight occurs on that spot, the Mirage ability becomes active, along with any effects of the Active Location. Only 1 Mirage can be on the field at a time, so when a new Mirage finishes its time as Active Location, you must place any Mirage on the field at the bottom of your Location deck.
Locations can have a pretty profound impact on fights, and choosing the right 10 Locations is key to any deck. Think about what abilities benefit your creatures and who can take advantage of Initiative.
