Ambidexterity

Type of feat: general
Prerequisite: dexterity 15+
Required for: improved two-weapon fighting

Specifics: When fighting with two weapons, this feat reduces the penalty of the off-hand weapon by 4.

Use: automatic

[edit] Notes

Rangers are prohibited from selecting this feat (on a ranger level), presumably because they receive the dual-wield feat at first level. (The dual-wield feat combines the effects of ambidexterity and two-weapon fighting, as long as the ranger is not wearing medium or heavy armor, but does not qualify as a prerequisite for improved two-weapon fighting.)

Item feat: yes

No special treatment is required by this feat.

Removable: yes

Reusable: yes

Script: hardcoded

A custom class must have this feat in their feat list, or that class will not be able to select it as a general feat.
