When the action to activate a power of an artifact is stated as Active, does it means that I must use my Active action of the turn (so for example I cannot attack with it in the same turn)?
Example: Shatter Armor: When attacking a reptile, the artifact’s master can choose to strike with the flat side of the spearhead and (if it hits) produce a shock wave which ripples through the victim’s
scaled skin. The attack does not deal any damage, but causes most of the scales to fall off. The scaleswill eventually grow back, but for one month, the creature’s natural Armor is reduced to 1.
In the example above, must I use my Active Action to activate the power, and then in the next turn attack with it, or could I attack immediately in same turn?
