Add support for Combination from the Martial Arts Book

[yoshisman8]

In the Martial Arts book (Page 80) the book outlines an optional rule for something they call Combinations. Ultimately, they a special Technique which has 2 or 3 Skill Levels which are tied to 2 or 3 skills or techniques.

Implementing this would likely re-use most of the UI for regular Techniques, but instead of having it Default to a single skill, it should have the capacity to have 2 or more skill "Defaults" which would all then be listed in the SL column, each separated by a Slash (Ex: 15/13/9).

Each skill should have 2 fields: The name of the field, as well as a modifier field that increases/decreases that skill for the purpose of the combination. This is because combinations have to specify the 'target' of the technique. So if your combination targets, say, the hand using your Rapier skill. It always targets the hand and the Rapier part of this technique has a permanent -4.

Combinations are Hard Techniques by default. And they cost an additional number of points to buy for the first time equal to the number of actions in that combination. So if your Combination has 2 attacks, it costs 3 points for the initial 'point'. Then each point afterwards behaves as normal.

You can somewhat recreate this functionality using advantages and techniques but it is quite janky. First you create one technique for each step of the combo (setting its default to the total penalty). then you create an advantage with a base cost of 2 or 3 (for a 2 or 3 attack combination) then have that advantage give +1 skill bonus per level to each technique. This will somewhat recreate the effect but it is quite janky.

In summary, what has to be added is a new kind of Skill (similar to how Techniques are their own skill type.

1 - In this skill type we set a name, notes, VTT Notes and categories as usual. 2 - Instead of it defaulting to one thing, it should have a space to add more than 1 default. Each entry asking the name of the skill to default to, and a penalty to said default to account for penalties to that given attack./ 3- The Difficult row can remain, but its default should be Hard instead of Average. And a new field called "Penalty" should be added for the global penalty applied to all of the skills set up (This penalty varies a lot so it's best to just have it be a separate field) 4 - The new combination would then just be listed on the skills section as X/Y/Z for each skill involved. The Relative Skill Level can still just show the total global penalty for that combination 5 - The first increment in the combination costs 1 + X points where X is the number of skills involved in the combination. Each subsequent increase costs 1 point as normal.

That should more than suffice for implementing the functionality.

I would love to see this get added personally out of everything else.
