The Drowned Ruins - Good Win Rate

This is a fun quest, and these decks beat it most of the time.

The key is to slow play and build up lots of questing ability before moving on to stage 2. Don't take any Underwater active locations until you know for sure you can easily finish them in one round, or, just wait for them to come out into the staging area from the Treachery cards, and finish them there using various card effects.

Threat can be a problem, but the decks have a lot of threat mitigation. Eleanor is useful to cancel some of the worst Treacheries. The most common way to lose is if threat gets out of control and/or you get swarmed early by enemies with bad shadows.

Player 1 needs Master of the Forge, Valinor, etc. Bombur is incredibly important to cancel threat in the staging area. Rhovanian Outrider is important. It's also a good idea to give resources to Captain Sahir and use him for questing. Getting questing numbers up early is crucial, as threat can build up quickly.

Player 2 does all the defending and fighting. Armored Destrier is very useful.
