In the Actions chapter, the rule says than some activities take times. To be honest, i am not sure to understand this rule.
I play that these activities consume 1 action (replace an action) but i have some trouble about the fact that some activities as Draw weapon, equip shield, open a door, can be included as part of a mouvement action. How to play ?
Use your common sense.
If you are the judge, and you think something is significant (i.e., you could not do it while moving), it takes an action. If not, then not.
If you are a player, the judge decides.
The alternative is a list of actions, move actions, free actions, half-actions, etc. that must be consulted for each character each round, and the looonnnnggggg combats that result, where 3 rounds of action take 30 minutes to resolve.
Personally, I prefer the DCC way.
