How to do this weapon enchantment in HL

[Bebberino]

Sharpness

Description

This ability doubles the threat range of a weapon. Only slashing melee weapons can have this enchant. If you roll this special ability randomly for an inappropriate weapon, reroll. This benefit does stack with any other effects that expand the threat range of a weapon (such as the keen edge spell or the Improved Critical feat). Also, this enchant raises the critical multiplier by 1 for the affected weapon.

Construction Requirements: CL 15, Keen Weapon, Dimensional Blade, Price: +4 Bonus

How would I add this to herolab and have it show on the affected weapon?

Thanks

I would look at the Keen enchantment property.

The stacking with other crit expansions means looking at keen is probably not going to help. I would run a script after Keen/Improved Critical do their thing and replace the tag with one less value.

For the increased crit multiplier, look at the fighter's weapon mastery ability.

perform eachpick.assign[Broadcast.CritMult]

What is Broadcast?

[Aaron]

Just a tag group

I will work on it, gotta say it isn't simple, that's for sure.

Thanks

There's an option, I assume from the Community Pack, where you can check to have Keen and Improved Critical stack (by default they do not)...

Not sure if that would help, or not.

This option is in fact part of the core program. It would indeed be where I'd look first to implement the OP's request.
