The game mechanics for a stealth sneak-up and backstab?..
Greetings, all!
Basic mentions needing to make Stealth rolls for sneaking up on someone for a garrote attack. Kromm mentions stealthy evaluate maneuvers... Is there some set of guidelines as to the modifiers, frequency of rolls etc. when using Stealth? To me, the skill seems like it needs a long description (probably equal to half of Combat Lite), but it doesn't. Thanks in advance to all who answer! |

Also, the hearing penalty is hard to find. What is the 'default range' for sound-based Stealth? |

Re: The game mechanics for a stealth sneak-up and backstab?..
Sorry for the thread necromancy, but I was wondering if there has been any word from Kromm about the 4e mechanics of stealth. As far as I can tell, Molokh's questions in this thread haven't been answered elsewhere in the forum, and I don't find the word "stealth" in the list of official FAQ topics.
Thanks in advance! |

The noise and distance material in High-Tech (discussing silencers, but generalizable) probably has bearing.
The backstab itself is well covered by Telegraphic (optionally All-Out) Attack for whatever target location seems best. How much rolling for stealth the sneaking-up process requires, I don't know. |

Re: The game mechanics for a stealth sneak-up and backstab?..
Personally I'm against "roll every turn" on an all-or-nothing thing like stealth. The nature of probability means that your chances of failing are snowballing every time you roll again. And a single failure I would assume means he notices you. So my ideal solution would involve a small amount of rolls in order to execute this. It shouldn't be easy as it's pretty close to an insta-kill if you're standing behind someone with a weapon and they don't know it, but it also shouldn't require a whole bunch of rolls, IMO.
EDIT: Normally I make one stealth roll per character for every "scene" in which they're trying to sneak. I think counting stalking a target to backstab could be considered such a scene. They make their stealth roll, the target makes their perception roll. If the ninja makes it by enough that they can get all the way behind them before the target successfully hears them, they get their backstab. If the target only makes it by enough to hear them within x amount of yards, I let the player sneak up till they get that close then the target hears them and regular action commences.

(There is an abstract rule in Dungeon Fantasy). Usually I require a Quick Contest between Stealth and Perception. This will allow you to get at, say, 10 yards from your enemy. Then I ask the PC for more rolls if he wants to get closer... a good guideline could be the Range/Speed increments, e.g. one roll at 10 yds, then another at 7 yds, then 5, 3, 2 (and then, ATTACK!)

Re: The game mechanics for a stealth sneak-up and backstab?..
Well, basically with telegraphic attack available you do not need evaluate when approaching from behind..
As for how often to roll.. Well the rules do not say anything specific except the hunting thing.. "A successful roll (and about 30minutes) gets you within 30 yards of most animals. Another roll, at -5, gets you within 15 yards." But there is apparently no opposed roll.. As for how I have done it is: 1 day at distant stationary observation like a OP. 1 hour of following someone at edge of vision range behind. 10 minutes of closing at far distances(actual distance varies with the terrain) 1 minute at medium distances. 10 seconds at close distances(about the last 10 meters normally, requiring 1 roll for s stationary target, 2 for slowly walking sentry) and 1 second if they stay really close to the target.. |
