I'm creating a PF1 Human Swashbuckler. As a class ability, he gets "Swashbuckler Finesse", which allows him to use Finesse on single-handed as well as light melee weapons. I equip him with a cutlass, and add the feat Weapon Focus (cutlass). RAW, I should now be able to give him the Slashing Grace feat, but pcgen doesn't allow it. The Requirements text has "all of ( at least 1 Weapon Finesse FEAT )" in red. I add a GM bonus of an extra feat, and apply Weapon Finesse. Now Slashing Grace shows up in black, but selecting it and clicking Add Selected does nothing. Is there any way I can get this to work? Using version 6.08.00 RC8
Based on the rules below, it should in fact work.
The error you see reported in red, indicates it isn't counting Swashbuckler Finesse as Weapon Finesse: "all of ( at least 1 Weapon Finesse FEAT )"
This a known issue and in their bug database. It has not currently been fixed, but a pull request has been submitted.
There is also another bug that prevents taking Slashing Grace even when you have taken Weapon Finesse. This bug has been in the system since Aug 2021.
The first bug has a PR (a patch from a third party submitted to the developers). The second does not have a PR attached, so the developer would need to solve the issue.
Swashbuckler Finesse says:
gains the benefits of the Weapon Finesse feat with light or one-handed piercing melee weapons, and she can use her Charisma score in place of Intelligence as a prerequisite for combat feats. This ability counts as having the Weapon Finesse feat for purposes of meeting feat prerequisites.
A cutlass is defined as:
Damage 1d4 (small), 1d6 (medium); Critical 18-20/x2; Range —; Type S;
Slashing Grace has the following rules:
Choose one kind of light or one-handed slashing weapon (such as the longsword). When wielding your chosen weapon one-handed, you can treat it as a one-handed piercing melee weapon for all feats and class abilities that require such a weapon
