Currently restarting work on making my Homebrew game. Based in an Archipelago, the game will contain a large amount of naval travels. To make these moments interesting, most overworld travel was connected to something such as a Random Encounters Table. But I thought to use something different, ish...
The plan is, for every X amount of distance (Hex, Miles, Etc) they player flips a card from a deck called "The Blue". On each card there is a chance of getting some options, most will be "Clear Waters" with something around 40-55% being this card type, as this will not slow down travel too much. But there remain percent will be a collection of events. First the Card will Ask where in the water you are. 3 Options being, Shoreline/Shallows/Deep. The Shoreline is any time their ship is close to land, for example if the map was Hex based, if one edge is Land, they are Shoreline. Shallows are the part between the Deep and Shoreline, usually a Hex or so out from the shore. And finally, the Deep is anywhere else that isn't land...
After that, it would explain the Event (or at top of card, meh details). These could range from "Sails on the Horizon" to "Uncharted Landmass" which has you roll on a table connected to the location. An example of Uncharted Landmass for Shoreline would be something like;
1-5 - Sandbar, nothing interesting.
6-8 - Sandbar with Flotsam (Basic Treasure Loot)
9-15 - Reef, Slows Traveltime to Coursealign
16-18 - Small Island, Roll Event (D4 - 1-3 Nothing, 4 - Castaway)
19 - Small Island, Roll Event (D4 - 1-2 Castaway, 3-4 Loot Minor)
20 - Small Island, Roll Event (D4 - 1 Castaway 2-3 Loot Minor 4 Surprise)
And so forth. Problem is, after Sails, Uncharted and Weather. I can't really think of any other Events, NOR can I think of the Table Results. Anyone got any ideas? Not asking for someone to make them all up themselves, but just help me start this wave crashing
