Does anyone have a game mechanic for noise in dungeons. How do you decide if other monsters are alerted and come to investigate? DM fiat?
I am less interested in whether the monster physically hears the noise; what I am interested in is deciding if the noise they hear is worth investigating. Some dungeons might have lots of noise and in-fighting may be common.
I was thinking of:
Starting chance of being alerted by noise is 6 in 6
For every 20 feet reduce by 1 in 6
For every door or corner reduce by 1 in 6
This assumes the monster can't see the combat, where the chance of being alerted is 6in6.
In hyperalert states (monsters recently attacked) this could reduce to every 10'. Relaxed unalert states 40'.
Thoughts? Too cumbersome?
Whatever the case - wish me luck. I DM Keep on the Borderlands tonight. It's why my blogging has slowed as I prepared.
My first DM attempt in 17 years, to a group of aged novices. I may need more than luck!
