On several occasions the Iniative must be determined to assign the first strike to one of the opposing sides.
The Initiative roll is an Opposed Roll of Perception between two characters of the opposing sides.
When fighting against characters of an ADP , the Initiative roll is always between the closest hero (or ally) to the next enemy and the enemy with the highest Perception , meaningless how far away that enemy is away from the heroes group.
Each time the Dark Player places a new character or creature in a section which has just been revealed, or as a result of playing a card or an event, the corresponding Initiative roll must be made between the enemy characters closest to each other.
As soon as a character discovers an unexplored section for his side and visualizes enemies in it, there must be made an Initiative roll against the closest enemy in the section immediately.
If the heroes win the Initiative roll, a new turn for them will immediately begin (without the Dark Player being able to draw cards or add Achievements).If the heroes lose the Initiative roll, the turn ends for them and the turn of the opposing side begins.
Initiative rolls may also be made due to the spawning or placement of new enemies when the heroes' side is already in combat. In this case, if the new enemies (the Perception of the one closest to the group of heroes is considered) lose the Initiative die against the nearest hero (or mercenary or pet), they will not activate in the turn in which they are placed, and must wait for their next turn. If these new enemies win the Initiative roll, they may activate immediately as soon as they are placed.
If new enemies are spawned during combat, a new Initiative roll must be made. Then they will activate immediately if they win the Initiative, but will not activate this turn if they lose it.
Caught by Surprise!
As soon as an Initiative roll is made (after both sides have met when a new section is revealed), enemies 6 or less squares away from the character or creature that won the Perception test will be affected by the "Caught by surprise!" rule if both dice rolled by the winning side equal or exceed the Intelligence of the enemy who rolled Initiative against them.
Example: If an orc with Intelligence 3 loses the Initiative roll against an elf that got a 3 and a 5 on its roll, the orc will be considered affected by the "Caught by surprise!" rule, because the two individual results of the dice rolled by the elf equal or exceed the orc's Intelligence. The characters affected by this rule in the losing side can be moved by the winner (choosing their facing too) to an adjacent square free of obstacles or characters.
Characters and creatures will never be affected by this rule if they new section was revealed after breaking down the access door.
If one of the sides gets a critical failure (double 1) on their Initiative roll, all the characters in that side within the 6 square radius mentioned above will be automatically affected by "Caught by surprise!"
This rule cannot be applied to a side which is already in a combat turn.
