Couple of prereq questions.

[AndrewD2]

These both have to do with "or statements"

first: I've got a feat that has the requirement of 2 ranks in skill a or b. I tried using #skillranks[skA] + #skillranks[skB] but if I have 1 rank in each it satisfies the expression.

I saw a way of using | for or, but I couldn't get it to work in this situation. (The reference in the forums is for checking races).

I know I could just do 2 if statements, but it just seems like there has to be a better way than that.

second: Is it possible to make a prerep mutable? One feat I'm inputting has a required of "Int 13 or Cha 13 (whichever is your primary casting ability).

Thanks,
Andrew

Anything that is more complex than 1 line can't be in an expr-req, it would have to go in a pre-req script. That's the way you'll have to go.

I know that, I working with pre-req here.

The "|" means "or" is only in tag expressions, you can't use it in most eval/pre-req scripts (the exception only applies to tags, whereas you want field values here).

Two validif statements is how I would handle this first one.

validif (#skillranks[skWHATEVER] >= 2)
validif (#skillranks[skWHATEVER2] >= 2)

For the second, you have 3 choices.

1 - You could just have a pre-req check for Int 13 or Cha 13 and be satisfied.

2 - You could make 2 versions, an Int version or a Cha version, and give them seperate expr-reqs (relying on the user to add the one they want).

3 - You could make the feat have an eval rule which tests for the correct Stat based on a user choice. Eval rules don't execute until after the user adds the feat, but are necessary when the pre-req relies on a user choice.

You will have to make the feat select the class desired, and then you can detect the linkage[spellattr] to detect whether it has Cha or Int casting, then make it check for 13 in that attribute.

Post Attr 10000

validif (field[usrChosen1].chosen.linkage[spellattr].field[aFinalVal].value >= 13)

Alternately, you could have the user select the attribute directly (rather than looking at the class, and transitioning to the attribute used to cast for that class).

Thanks, I just went with using multiple validif statements, works like a charm!
