I hate stair-scumming, and Sil does nothing to prevent that
Hi there. I'm glad you're enjoying the game. I just registered to correct this statement. Since we'd generally like optimal gameplay to be fun, we
were somewhat concerned about stair-scumming (although we're happy to have the stairs as an escape), and we put in some mild measures against this:
Using the stairs increments the turn count by 100, and also uses 100 turns' worth of food. Thus it counts against you in terms of two clocks: the food clock, and the forced descent of Morgoth's power calling you down, which pushes you down to a deeper level when you've taken too many turns. It doesn't use any turns of your light source because we didn't want to encourage players to unequip their light source before taking the stairs. We hope that this is enough of a discouragement to stair-scumming, but these measures could always be increased if it turns out that's needed.
Anyhow, I realise that this wasn't in the manual, so there wasn't any way you would have realised (except perhaps trying to abuse the stairs ridiculously yourself), but I thought I'd let you know.
Have fun with the orc soldiers! They get bigger bonuses to hit you if they're spread out and attacking you from all sides rather than lined up on side, so they will normally try to do this if you give them the chance.
