So running my first group through Sea of Blood and there's been the usual litany of mistakes (400g per treasure pile? Cash rewards for masters? My favorite: using JitD monster cards instead of the SoB stats) but there hasn't been too much pain. Except none of us are sure exactly how lieutenant battles work out. I brought out the Siren early to start sieging bindings and the party rushed to stop her. Fabulous.
So the party arrived at the Narrows of Gracor to stop her, and we stared at each other. Do we use the generic island map? The one specific for the Narrows? Is it just the lieutenant and her minions or are the 'usual monsters' there too? Can the party come back for the regular island encounter after the lieutenant is chased off?
Thanks for your help. I did try searching the faq and the forums before asking the typical newbie question; I look forward to being gently pointed at the proper page in the rules.
When the heroes attack, or are attacked by, a lieutenant, an encounter ensues that is similar – although not identical to – a normal encounter.
Then follows the 6 differences between a Lt encounter and a normal encounter.
First, rather than drawing an Incident card, the overlord uses the lieutenant’s card as the encounter’s Incident card. In addition, if the “Shipwreck” location card is drawn, discard it and draw again.
None of the other differences mention location, so a Lt encounter is the same as a normal encounter wrt location. You have already drawn the 'incident card' (well, in effect, not reality, since you are using the Lt card to replace that draw).
Incident cards without a prominent “non-combat” designation generate combat encounters. When these cards are drawn, the overlord shuffles all of the Location cards and draws one.
There is your first answer. Draw a location card (redrawing if you get shipwreck), which means use the other, empty-sea side, of the island map, with additional terrain as indicated on the location card.
The only monsters are the Lt and its minions, though additional monsters maybe reinfirced according to the Lt's capabilities. And if a Lt has Hordes of the Things it will get two additional monsters of course.
The Island dungeon level is a different thing entirely and totally unrelated to the Lt encounter.
Edit: Monster setup rules are on pg17.
