Sleeping Gods

On your turn you first take a ship action, then draw and resolve one event card, then perform two actions (you may do the same action twice), then end your turn (pass the captain). (p.6, p.10)

Yes — you may spend command at any time, even on other players’ turns (with some exceptions); you can spend command to equip/activate abilities, give combat tokens, or have other players use crew in a challenge (which itself costs command). (p.17–18, p.19)

Choose participating crew (each gains 1 fatigue), total their skill values, then draw a fate card from the ability deck and add its fate number to your crew skill total; you may then spend command or discard ability cards to modify the result, and if the final number meets/exceeds the challenge you succeed. (p.19)

When you hit you place all damage from that attack adjacently on the enemy card (no diagonal, one token per square), and if the enemy is not defeated it immediately counterattacks dealing its basic damage plus uncovered bonus symbols to the attacking crew member (you may apply block against the counterattack). (p.23–24)

No — you may not equip an ability card in the middle of combat or in the middle of a challenge; equipping costs command and must be done outside those sequences. (p.17)

If a crew member reaches 0 health during the enemy counterattack they still resolve their attack (they get to deal 1 damage if they missed) and may use abilities until the end of their combat action, but afterward they cannot participate in challenges or combat until healed to at least 1 health. (p.24–25)
