Use Case

Original Notes -- ignore

1. Allow GM to target one or more characters
2. Enter situational modifier
3. Chooses to Roll surprise.
4. One die is rolled
5. The die roll is added to each individual character’s Surprise Modifier to yield the result for each character.
6. A text box reveals which characters are surprised and which are attentive
7. Surprised characters automatically get the Surprised condition applied to them

Capturing discussion from Discord Discussion with @LeRatierBretonnien @ArcanistWill @Archon-Autarch ... Task summary from @LeRatierBretonnien point of view :

• Add of a "Roll Surprise" button in combat tab
• When clicked, the GM select the situation based on the table provided here ⁠Archon, LeRatierBretonnien⁠
• Then the GM can select a modifier for both parties
• Then a roll is done for each player + monster, with the GM modifier and their personal Surprise modifier
• The result is displayed in the chat
• The result is applied to each PC/NPC, with an icon displayed on their token and in the combat tracker.

We all agree this makes sense. I'd like to note that there still probably needs to be a Surprise Modifier on the character sheet if that wasn't clear.

Design Notes Which characters are Surprised?

• Surprised characters don’t get to act in the first round.
• They should be shown to the GM with a marker
• During Initiative countdown they should be skipped, automatically if possible.
• The flag on surprise comes off at the start of their next initiative.
