The “metered” fighting style is a discipline that parallels a pattern of rhythmic metered units within a poem. The monk commits a poem to memory and recites it silently during combat.
The smallest metrical unit in poetry is called the “syllable”. There are two kinds of syllables: stressed and unstressed. The fighting style mirrors these metrical units in combat. Stressed syllables represent the execution of quick thrusts or strikes. Unstressed syllables indicate executing counters or defensive maneuvers. The metrical unit in poetry known as the “foot” is a group of two or more of these stressed or unstressed syllables. This metrical unit is represented in the fighting style as a more extensive series of move combinations. A foot predominately containing stressed syllables is considered more offensive in nature, while a foot predominately containing unstressed syllables is considered more defensive. The strengths of this style lie within its precision, accuracy, and strict discipline. Its weakness comes in successfully finding and maintaining the metered rhythm of the selected poem.
Unearthed Arcana presents new fighting styles to better represent the varied styles seen both in real life and in martial arts movies. In exchange for the freedom to choose her bonus feats, a monk who takes a specific style gains a +2 bonus on a specific skill and at 6th level can gain an additional ability if she meets lhe prerequisites (she must meet the prerequisites at 6th level to gain this ability). The metered fighting style incorporates a pair of new feats.
1st-Level Skill Bonus: Concentration.
1st-Level Feat: Defensive Metered Foot.
2nd-Level Feat: Offensive Metered Foot.
6th-Level Feat: Toughness.
6th-Level Bonus Ability: You may take 10 on any Strength- or Dexterity-based skill check, even if distraction would normally not allow you to do so. Prerequisites: Concentration 9 ranks, Skill Focus (any Strength- or Dexterity-based skill).
Although usually associated with the metered lighting style, these feats are available to any character who meets the prerequisites.
