Little heads up, added lots of numbers and examples for in combat stealth calculations to above post on stealth.

Added the watch system to above post on stealth - subjective me likes it very much :-):

To spice things up even more a bit there's one exception where a character who has already entered stealth can be unstealthed during his own turn: the Watch action of his enemies (it can easily be designed as a complex effect of a trait). It requires a full attack action and a full move action, i.e. you can only activate on the very start of your turn and it costs you the full round (attack+move), only other free actions are possible. When an enemy is in watch mode, he forces every stealthing character who enters a square that is in three squares radius around the watcher to do a stealth check as described below in detail, but always against a diffculty number detrmined by the watcher (and not the best perceiver, see below). Please note that a watcher can only once force the same stealther to do this check per round round of this stealther. Also please note that this check is only triggered by the move of the stealther, not the activation of watch mode. Finally a character who is uncovered in his own round, canot re-stealth again on the same round. I have added watch mode to new example 4 below to clarify more.


and

Example 4:

This time Gareth, the thief (Stealth Skill Value 7, including all modifiers for skill level, dex attribute, leather armor worn) tries to enter stealth quite some distance away from guardsman Alfred who turn his back to him (Perception value 4, Distance 5) in a starry night (Brightness level 4), two further guards, Bert and Casper (Perception value 4, Distance 11), stand a real long distance behind the guard Alfred, but look into the direction of Garreth. The only difference to example 3 here is that Alfred is watch mode (he spent his last full roudn to enter it and can do nothing else but free actions while in it).

So, as in example 3, clearly Alfred is the best perceiver (4 vs -2 vs -2). And again Gareth would only have to beat a difficulty number of 4 to enter stealth successfully (with his bonus of 7, only a natural "1" would prevent him from entering stealth).

Where things get different is as Gareth approaches Alfred - the moment Gareth moves into a radius of three squares around Alfred, the watch effect kicks in. Gareth is forced to do a succecesful stealth check on this own turn, right now, while moving. It is this time not to enetr stealth, but to maintain stealth.

Calculating this maintain stealth check, always using the watcher who triggered the check, here Alfred:
Subsetp 1a: Determine Perception Value: 4
Substep1b: Add brightness level of the square on which the stealther enters the three-sqaure-radius-perimeter of the watcher, values 0 (total darkness, muffled ground) to 10 (perfect illumination, no cover, ground contact create sounds very easily), let's say here that this square is a little brighter due to some light near Alfred, so it's 6 instead of 4 (where Gareth entered stealth): 4+6=10
Substep 1c. Determine relative facing to the character who tries to enter stealth;: if in front area (90 degrees front) multiply with cumulated results from substeps 1a to 1b with 2; if right or left flank leave value as is, if in back area (90 degrees back) divide by 2, results in 0.5 (Alfred still has his back turned to Garteh) * 10 = 5
Substep 1d: Add 15 minus (3 points for each square distance to the character who tries to stealth), note that this time Gareth is much closer, only three squares to Alfred, so it results in (5+15-9):11
Substep 1e: Add 0 for the addtional guardman within three squares of Gareth (they are too far away).
Endresult: 11

Suddenly, there's chance that Gareth is uncovered. He now needs to roll a 4 (4+7=11) to mainatin stealth. Would Alfred not have his back turned to Gareth, but actually had faced towards him, this would have gotten real nasty (dc 26, roll of 19 needed). Please note that when Gareth successfully makes this roll, Alfred gets no second chance on this round of Gareth to uncover Gareth. Gareth can freely cross the remaining two squares to Alfred and drop in for the kill. If on the other hand, Gareth is uncovered and loses stealth, he still can move and attack. But it will not be from stealth anymore (no backstabbing, full rules for attacks of opportunity). Also, now all enemies would see Gareth as stealth is always absolute in this system. Big trouble to get uncovered this way if many enemies are in the close vicinity :-). Oh, and a character uncovered in his own round, cannot re-stealth again on the same round.
