Creating a class special that can ignore 1 feat prerequisite.

[Mauron]

Is this possible? After gaining the ability, any future feats taken would be valid if only one prerequisite failed. For example, a character with strength of 13 could take Cleave without having Power Attack.

Not really. You would have to modify all of the feats, and by your description I assume that any one pre-req could be ignored, which would complicate things. I'm not sure off the top of my head how to script it so that just one pre-req was ignored.

One alternative option would be to try to ignore all pre-reqs by using the tag thing.skipprereq, but even then you would probably only be able to apply that to feats already selected.

Another would be to be more specific in what this special ignores. Using your example, you could use this special to assign the tag "HasFeat.fPowerAtt" to the hero which would make HL think the character had the pre-req for Cleave (but it would still require STR 13).

I had a feeling this wouldn't work well. Modifying all of the feats isn't out of the question, since I'm trying to implement Farscape d20, and the book only has about 50 feats.

I figured out a way to do it. I'm posting it in the unlikely event someone else needs it.

This was set up as a prerequisite with no message text.

var errorCount as number
var errorText as string
errorCount = 0
errorText = ""
~test condition 1
if (child[Attack].field[tAtkBase].value < 1) then
  errorCount += 1
  errorText = "Base Attack Bonus 1 required"
endif
~test condition 2
if (child[aDEX].field[aFinalVal].value < 13) then
  if (errorCount > 0) then
    errorText &= ", "
  endif
  errorText &= "Dex 13 required"
  errorCount += 1
endif
~ No errors, continue.
if (errorCount = 0) then
  @valid = 1
~ has appropriate levels for the required special. I tried testing the class special itself, but didn't find a way to see if it was active.
elseif (#levelcount[Scavenger] >= 9) then
  if (errorCount = 1) then
    @valid = 1
  else
    @valid = 0
    @message = errorText
  endif
else
  @valid = 0
  @message = errorText
endif

Now I just need to redo my feats.

Thanks for posting this. I assume this gets put on each feat?

[Mauron]

Yeah. All the prerequisites are handled through the series of if statements on the one rule.
