Skill Check: Special Effects on Critical Success/Failure

[jkeller]

Is there any way to automatically do something when a PC rolls a skill check and gets a 1 or a 20? Or an extension that does this?

I'm thinking of something along the lines of the Crit/Fumble tables, but for skill checks instead of attacks.

Thanks!

You would need an extension; but I don't know of one. It would all depend on what you want to happen when the 1 or 20 gets rolled.

Nothing fancy. Just roll on a table and show the result in the chat window. The trick would be to use a different table for each different skill.

This might be something I could develop (I'm a programmer), but I'm not even sure where to begin. Any suggestions would be most welcome!

Theogeek has an extension that does special criticals on a natural 20 for attacks, but not for other skills checks. So it's possible, but like Mr Z, I'm not aware of any extensions that do what you are wanting.

There's an example of this in the 5E ruleset scripts\manager_action_attack.lua file - the onPostAttackResolve function that calls ActionAttack.notifyApplyHRFC with the name of the table to roll - for example: ActionAttack.notifyApplyHRFC("Critical Hit"); would roll on a table called "Critical Hit".

You could do something similar for skill checks - in the scripts\manager_action_skill.lua file - the onRoll function determines the success level, and you could override this function in an extension and determine if a table has to be rolled and which table to roll.

Try the attached extension as an example (5E Skill Crit Table) - the code is in the my_manager_action_skill.lua file - in the "-- Custom code" section.

This will check for a 20 or a 1 and then roll on a table called either "Critical Skill - XXXX" table or "Fumble Skill - XXXX", where XXXX is the skill name parsed from the [SKILL] XXXX chat data.

This means you'll need different tables for each skill. Change the code to whatever you'd like!

EDIT: I've updated the extension - made it more future proof (i.e. using less code from the 5E ruleset) and made it handle skill names with spaces properly.

Thank you so much! I will give it a try

I've edited the extension - updated in post #6 above.

Thanks Trenloe. I'm glad to see there's a way to invoke the default implementation, without having to copy the code.

I've got it installed (locally) now. So far so good!
