Yesterday we played Descent for the first time with friends. It was a blast!!
However, there are 2 things I did not understand: I had a spider in a 2-square-wide corridor. In the corridor there was a small lake too. (1 square). The spider occupy 4 squares. How can I make the spider (or any other big creature) go through the lake? Or a hole?
Go through a lake? You can't
. One of the disadvantages of large creatures is that sometimes they get screwed by terrain.
The 'lake' is an obstacle called 'water'. The effect of water is that figures may not enter that space (nor may they jump over it). If a figure has Fly or Acrobat abilities it may enter the water space as it is allowed to ignore the effects of obstacles (so it can ignore the effect of the water that stops you entering it), but it may still be restricted in other ways - read the text of Fly and Acrobat.
On the other hand, one of the advantages of large monsters is that sometimes they can ignore terrain. When entering terrain, large monster may ignore the effects of that terrain unless all their spaces (eg all 4 spaces of a spider) are in terrain. So for a 1 or 2 space pit (hole) the spider can just ignore it if it chooses to.
Note that large monsters can do this (ignore the terrain) when entering
terrain, so if the effect of the terrain is to prevent them from entering
, they cannot ignore that effect.
Second: If you use fatigue, you get movement points... So, if you spend a fatigue, when you are out of movement points, you can drink a potion for a fatigue?
