Also, the berserk system looks to see if someone is in a room before charging in and attacking the critters there. If you're hidden without indication (I'm not sure a disk will work, but the hiding flag does), the system doesn't see you, which means it can force a berserking character to instantly attack the critter as they are forced to enter the room from an adjacent location. Just use the flag if you're hunting, make everyone's day better.
You swing a glowing white sacred warsword at a silver-scaled cold wyrm!
AS: +690 vs DS: +371 with AvD: +16 + d100 roll: +77 = +412
... and hit for 80 points of damage!
Pained spasms wrack the battered form of the great cold wyrm. The vanquished wyrm gasps futilely for breath, the gelid, caustic spittle bubbling up from her mouth shot through with silver-sheened crimson blood. With a last, terrible convulsion, the wyrm crashes to the ground and lies still.
