I can tell I've had a good Dream Quest run if I look back at my phone's camera roll and see
a bunch of screenshots. (Also, I can tell because I remember playing the game.)
Typically, you want to get rid of weak cards and make your deck very potent in that game. The ranger is one of the classes that facilitates a contrary strategy. The ranger gets a lot of opportunities for equipment slots. Last night, I decided to just take as many as I could. In the end, I ended up with six.
The ranger, like most of the classes, starts off with a lot of "Attack 1" cards, which are fairly useless. They do 1 damage and nothing else. This time, I kept all of these cards because I was able to pick up a lot of things that made them valuable:
1) Scimitars: These let you play a copy of any card named Attack whenever you play an attack card. I used the mushroom field to duplicate this piece of equipment so I had two Scimitars cards.
2) Donnerschwert: It deals a point of lightning damage every time an attack card is played.
3) Cruel: This was a talent, rather than a piece of equipment, but it added one damage to every source of physical I played.
4) Expose: This was an action card (so I had to be lucky enough to draw it, unlike the above three enhancers) that added 2 damage to every source of damage I played.
So, playing a single Attack 1 card meant I actually played 3, due to the Scimitars. Then, Donnerschwert added a point of damage to each of those, and Cruel added 1. The result of playing the one card was 9 damage. If had happened to play Expose, then the total would be 15 damage.
Because I had a lot of things that let you draw extra cards, I sometimes played 5 attack cards a turn (some of them Attack 3 instead of Attack 1) resulting in 15 being played for at least 45 points of damage.
Then, I had a bunch of armor to help with not getting hurt. Most battles on the penultimate level (the last level has just the final boss) took two turns.
It's really impressive that Dream Quest 1) is still worth playing after five years and 2) facilitates very different approaches to the game.
