Giving vulnerability to alternative racial trait

[SeaanM]

I am trying to figure out how to add a vulnerability (say xVulFire) to an Alternative Racial Trait. I imagine the assignment in an Eval Script would be something simple; using something like #applyvalue, or the right combination of field[something].something-else and an appropriate value to assign it. Tried a number of things at random, but I could never get anything to compile.

So of course, no documentation to be found. So then I searched for any examples items or races that had vulnerabilities (so I could see an example), but could not find any (mostly in bestiary monsters). Than I searched this forum and the authoring wiki. No luck.

My current work around is to add a situational note to all saves, but I would prefer to find a method that displays this information in the "Specials" tab.

Another method I have tried is making a Racial Special. Only problem here, is that I am selecting a value (dragon type), and applying the appropriate vulnerability. That means for this alterantive, I would have to figure out how to add the Racial Special to the Alternative Racial Trait using a script (so I could either select the Racial Special with the corresponding correct energy type, or pass a value to the Racial Special). Suspect this is harder to do than my first approach...

Try bootstrapping the xVulFire pick to your ART.

Picks can't be added directly in an eval script. If you want xVulFire to show up only under certain circumstances (like when you're raging or something else), you can add a bootstrap condition that is satisfied by some eval script.

Good pointer, thanks. Had not gotten around to reading up on bootstraps yet (experienced programmer, but new to HL).

BTW - I found the perfect example (not sure how I missed it earlier), but in Racial Cust Special there is an entry Vulnerability (rcMutVulne) which does exactly what I needed. It includes a nice example of bootstraps.
