A character can use any combo he knows that is within his Combo Rating. Using a combo is a 4SA. The entire combo happens simultaneously. The player has to choose before rolling how many attacks are against which enemies, etc.. All the dice should be rolled at once. If a combo has multiple damage dealing attacks, do not add the damage together . For example, Colonel Mauve attacks a Goblin Mook. Mauve hits three times with an arming sword, so rolls three d8s, and adds +3 to each (his strength score). The results (including the strength bonus) are 8, 6, and 4. The Goblins toughness is 9/3, so the Goblin is wounded three times (8, 6, and 4 are all above 3 but below 9). If the damage were added together (it isn‚t! Here‚s why) it would total 18, which is enough to kill a Goblin eight times bigger in a single hit.
