A module for FoundryVTT that shows results of initiative stealth check vs combatant perception DCs on the initiative messages when Begin Encounter is clicked.
When Begin Encounter is clicked on the combat tracker, this module appends GM-visible results of checking the initiative stealth value against the non-allied combatants to the initiative roll message, grouped by detection status: Unnoticed, Undetected, and Observed. The numbers by each listed token in the groups shows the difference between the stealth initiative roll and the perception DC of that token. Unnoticed and Undetected status means that the token rolling initiative was not observed by the listed tokens, so the number listed will be zero or positive. Tokens listed in the Observed group are able to observe the stealth-using token.
In the above, Amiri's stealth roll of 16 was successful against monster and creature, who had perception DC's of 10 and 13. It was not successful against beast or grumpkin, who in turn had perception DC's of 17 and 20. If Amiri had been behind standard cover relative to beast, then Amiri would have a +2 to stealth and thus would be Undetected instead, but would require the +4 from greater cover against grumpkin in order to be Undetected by it. PF2e Avoid Notice will apply this bonus automatically if the token rolling stealth has an Effect: Cover (Standard) or Effect: Cover (Greater) effect on it unless PF2e Perception is active.
An Unnoticed setting controls whether or not to use Unnoticed rather than Undetected for stealth checks that beat both the target's perception DC and initiative. Undetected is always used if the stealth initiative roll beats the target's perception DC but doesn't beat the target's initiative roll.
The 'Pathfinder on Foundry VTT Community and Volunteer Development Server' discord server leads to the excellent unlisted module PF2e Perception. It isn't required for the overall operation of this module, but additional capabilities become available:
- PF2e Avoid Notice will set the appropriate visibility flags on the combatant tokens to reflect the detection status determined by stealth initiative checks.
- An Override setting allows PF2e Avoid Notice to override existing PF2e Perception visibility flags on tokens. Disabling this is useful if one wishes to setup any complicated situation beforehand and not get it stomped by the initiative rolls.
- If PF2e Perception cover flags are found on a token using stealth for initiative, standard or greater cover bonuses will apply as appropriate against perception DCs.
- If Compute Cover at Combat Start is selected, *`PF2e Avoid Notice will ignore existing cover flags and use PF2e Perception to calculate new ones for tokens using stealth as initiative for each token they are testing against
