"Before you act" and "Cannot be evaded"

[Alex319]

The Demonling has a power that says "Before you act, succeed at a Wisdom or Perception 7 check or the Demonling may not be evaded, and the difficulty of checks to defeat the Demonling is increased by 3."

However, the "Apply any evasion effects" step of the encounter sequence is before the "Before you act" step. Does this mean that if I have a card that lets me evade an encounter (say, the Wand of Paralysis) that I can use it before the "Before you act" power fire, and thus evade the encounter without making the check? (If so, then the "Demonling may not be evaded" part of the power would only be relevant if I had an evasion power that worked in the middle of the encounter, such as the one on the Longspear.)

[Joshua Birk 898]

Here is the passage you are missing from the rules.

Apply Any Evasion Effects. You may use a power or card that lets you evade the card you’re encountering. If any powers on the card you’re encountering relate to evading the card, they take effect at this time. If you evade the card, do not activate any other powers on it. Shuffle it back into the deck; it is neither defeated nor undefeated,and the encounter is over.
