i have the base set.

i want to buy rtl, and i read that well of darkness works best with RTL.

is it true?

is the base set is enough to really enjoy RTL?

do u recommend any specific expansion before i buy RTL?

I recommend them all. They are great. Tho there is no harm in playing Base + RTL initially - since you're new to it, you dont exactly need "variety" yet, since it's all new to you. So I'd get base, and play that. Dont get RTL right off, since RTL involves playing for long periods of time over lots of weeks, and you'd rahter know if you like the game or not before delving into that. If you like it, then buy all 4 expansions, they all add cool stuff.

If you end up enjoying your first game of regular Descent, you'll want to get all 4.

thx for your response.

i read that there is not much use for the PROLONGED ACTION mechanic, which is part of AOD.

I can testify to the fact that Well of Darkness and Altar of Despair work great with RTL. I have been through two full campaigns already, and am working on a third. During our third we added in the Tomb of Ice components, which also are a lot of fun. So having played with all of the expansions with RTL, here is my take:

Well of Darkness: Great!
Great monsters, great potion, great heroes, great treachery cards. This is the best expansion to use with RTL.

Altar of Despair: Almost Great!
Great monsters (dark priests...*shudder*), GREAT heroes, good treachery cards. The potion included is fantastic for the base quests, but can't be used in RTL without house rules. A great expansion for RTL because of the monsters and treachery cards, but the prolonged actions and new potion won't add anything.

Tomb of Ice: Good!
Good monsters, good heroes, great potion, not good treachery cards. Tomb of Ice really shines in the base game, but not so much in RTL. A couple of the heroes aren't any good in RTL, even though they are great in the base game. The new potion helps out. Feat cards are tough to balance in RTL, so some groups decide not to use them at all. We added them in with our RTL using some houserules, and it seems to be going well. Treachery cards will be a let down if you have only this expansion because there are only a couple cards of each type, verses the many cards in WoD or AoD. Less excitement for the overlord in customizing his deck.

In short, when playing RTL, well of darkness is the best, then altar of despair, then tomb of ice.

Hope this helps, and happy descenting!
