Weapon Focus and Improvised Weapons / Normal weapon as improvised weapon

[Wonderstell]

I know that you cannot take Weapon Focus (Improvised Weapon), since it requires proficiency in the selected weapon.

But would the +1 to attack still apply if one used a normal weapon as a improvised weapon?

Example: A rogue with Weapon Focus (Dagger), who uses it incorrectly by bashing with the handle.

And would the normal weapon even count as an improvised weapon?

Weapon Focus wrote:

Prerequisites: Proficiency with selected weapon, base attack bonus +1.

Benefit: You gain a +1 bonus on all attack rolls you make using the selected weapon.

Special: You can gain this feat multiple times. Its effects do not stack. Each time you take the feat, it applies to a new type of weapon.

The most important question is the latter, which would determine if a monkey familiar can throw longbows or not.

Quote:

Can I use my longspear to attack at both 10 feet and 5 feet? I know that the rules for reach weapons don't allow them to attack adjacent foes, but can I use the improvised weapon rules to say that the blunt end of my longspear resembles a club and use it to attack adjacent foes? I know that the improvised weapon rules say they are for objects not designed to be weapons, but the blunt end of my longspear was not designed to be a weapon, right?

You could choose to wield your longspear as an improvised blunt weapon. In this case, it threatens only your adjacent squares, and not the further squares. If you are wielding it as a longspear, though, to threaten the further squares, then your grip precludes the use as an improvised blunt weapon. The rules are silent on how long it would take to shift between the two, but switching between a one-handed and a two-handed grip with a one-handed weapon like a longsword is a free action (and can thus be only taken on your turn), so it should take at least as long as that, thus preventing you from simultaneously threatening all of the squares at once. Incidentally, using the longspear as an improvised weapon in this way would not allow you to benefit from any magical enhancements it may possess, nor would you add benefits that apply when attacking with a longspear (such as Weapon Focus (longspear), but you would apply any benefits from using an improvised weapon (such as Catch Off-Guard).

You essentially want to do the same thing with a dagger, so the bolded quote applies.

When you use one weapon as an improvised weapon, you are no longer using the original weapon.

Great!

That answers both my questions. Thank you both for the quick reply!
