PC's and humanoid NPC's wield weapons, that has a critical rating describing how many boons are needed to trigger a critical wound (hand weapon 3 boons, Two-hander 2 boons, etc...).

What about monsters? Are this in the skill cards they have? Or am I missing some information?

Also as a sidenote, if an action has 2 boon effects, one with 1 boon, and 1 with 2 boons, and the player is using a hand weapon (3 boons), who decide how the boons are distributed, if you roll 3 boons for example. Is it up to the player? And then the GM rules over how Banes are distributed?

Hi!

First, boons and banes cancel each other out, so if a roll generates 2 boons and 1 bane, the net result is 1 boon. The player decides how boons are distributed, and the GM how banes are.

A monster has a critical rating too, if it wields a weapon use that rating, otherwise something else... 3 is a good number :-)

Monsters don't have CR in their default stats. If you give the monster a specific weapon, you use it's DR rather than the DR listed after their Strength and you now also have a CR; however, most of the monster special actions have boon results that are as good or better than triggering a critical from CR and you're rarely going to have enough net boons to do both.

Also, you decide the banes, chaos stars and how they apply. The player decides how they want to spend all the rest.

So if I have the following action in a burning barn: H - you hit; H H you hit for +1 damage; Boon - +1 critical; Boon, Boon - Perform a free maneuver; Bane - Your enemy gains a free maneuver; Bane - gain a fatigue; Chaos Star - you your weapon; Chaos Star - loose a wound from the fire.

Then if the player rolls 4 hammers, 2 cross swords, 3 aquilla, 1 bane, 1 chaos star (which equals 2 hammers, 2 boon, 1 star), so they hit for +1 damage, they decide to do the +1 critical, so they may not "buy" the free maneuver line, nor can they apply their weapons critical as it's at least 2. Finally, the game master applies the chaos star to have the loose a wound in the fire...though the GM could choose the former of the options if it felt good.

What mac40k said is pretty much the answer.

Even though most creatures don't have specific critical ratings in their stat lines, almost every creature type has a basic attack action that includes a way (sucess lines or boons) to inflict critical damage.
