Increasing Critters multiplier

Any way to do this?

In English, please?

There are some class abilities that do it, but they tend to be pretty high level, eg:

Weapon Mastery (Ex)

At 20th level, a fighter chooses one weapon, such as the longsword, greataxe, or longbow. Any attacks made with that weapon automatically confirm all critical threats and have their damage multiplier increased by 1 (×2 becomes ×3, for example). In addition, he cannot be disarmed while wielding a weapon of this type.

I believe they want to increase the critical multiplier.

Usually you cannot do so, and it is usually better to increase critical threat range.

Bolt Ace can increase the multiplier of crossbows.

Fighter can increase it for one weapon type at high level.

Don't know if anyone else does it.

Ooh, it's pretty specific but:

...and the critical multiplier for your bows and crossbows becomes 19-20/x3....

So if you're using a crossbow and you make use of this spell you're increasing your crit-multiplier. (BRACERS maybe? I think they used to be better ...?)

So between this and Bolt-Ace it looks like it's mostly about crossbows.

In English, please?

What Mr Charisma read it as.

And yes, I have a corner case (Devoted Muse) where the other might be more useful.

Alas, the world is not revolving around my desires.
