Final Fantasy Hacktics

I've used the search button quite a bit and I cannot find this.  I'm looking for an ASM which removes the 50% damage bonus gained from using a spear with the jump command.

Any help or information is very much appreciated.  Thank you for your time and have a nice day.

I searched and could not find answers to these questions.

1.
If a weapon has "Forced" Two hands, will it still have its attack power doubled if the unit is using the Two Hands support skill?

2.
Is there any ASM which allows Two Hands to effect skills which utilize WP in their formula?

Any help or information is very much appreciated.  Thank you for your time.
