Climb

[Hollowmaze]

the UP and Down exits of a room are hidden and not allowed to be moved through normally.
instead the player types Climb Up or Climb Down and they are then moved in the correct Z axis.
The use of the skill checks against Dex depending on the difficulty assigned to the Climb.
Easy - 30 Dex
Moderate - 50 Dex
Difficult - 70 Dex
Hard - 90 Dex

Should all UP/DOWN be hidden? or should climb act like a portal that's just an object in the room - like;

Climb Up Ladder
Climb Down Rope
Climb Up Rocks

[Hollowmaze]

an item in the room would give a hint that a climb option is available. Broken Stairs, Vines growing up the wall
