Possible to get absurd attributes by holding down 'h' in ID
Since using stairs doesn't take a turn, it is possible to hold down 'h' in the infinite dungeon to scum for room entrance effects. This nets you attribute scores of 1 St, 99 Le, 99 Wi, 99 Ap in something like 150 turns (most of which are spent wiping mud off of your face). Quite abusable in conjunction with potions of exchange.
