This is for D&D 5e.

I'm currently making a reoccurring antagonist NPC that is a master thief. It's CR 6 and I want it to be capable of making three attacks per round like multiattack but also have their thief subclass's enhanced cunning action with fast hands.

This would normally mean they'd get 3 attacks and a varying options for bonus actions, however I'd want them to be able to trade up to three if these attacks to have more uses of cunning action (this would of course stack the ability to dash 4 times per round but I'd just not do that while running the monster). They also have a special once per day ability that I'd want them to be able to swap a single attack for.

It got me thinking, instead of trying to make an unwieldy combination of multiattack, a special action and cunning action, could I just give them three actions?

The simple way this NPC works that I want them to pick 3 options from:

• Dagger
• Crossbow
• Special action
• Dash
• Disengage
• Hide
• Make an ability check
• Use an object
• Use a set of tools

At this point, what do I actually lose from letting them take 3 actions? They aren't a Spellcaster so I'm not worried about them throwing out three fireballs or the like.
