Duelists in ADOM

Yesterday I finished the initial duelist implementation for ADOM. Here's the text from the manual:

DUELIST -- A duelist emphasizes physical and mental acuity, and
precision in all things. Thus, the ability to accurately pe«rceive
their surroundings, and gracefully move through it, along with an
appreciation for the fine arts that help separate them from their
more thuggish contemporaries. They rely on the swiftness of their
strikes and their agility to keep them safe from harm. Duelists
differ between races however - while a high elven duelist might
elegantly skewer his opponents with a rapier while darting through
his defenses, a trollish duelist's idea of precision might be the
simple fact that their size, reach, and strength allows them to lunge
at their opponent from an amazing range and smash them over the head
before they can respond, while their mental acuity might be the simple
zen of knowing nothing but the clubbing, letting nothing interfere
with their "art". 

Duelists are trained in the following skills: Alertness, Athletics,
Concentration, Dodge, Find Weakness, Healing, Law 

All duelists rely on fighting unencumbered and using a single
one-handed weapon (and no shields!). When endowed in this way they
receive a multitude of benefits: All duelists receive an extra +1
to-hit bonus per weapon skill rank and +1 to damage per two weapon
skill ranks with their weapon. At level 6 they require 15 energy
points less for melee attacks per weapon skill rank for their
weapon. At level 12 they receive an extra +2 DV bonus for each weapon
skill rank in their selected weapon. At level 18 they can glove
slap opponents by giving gauntlets to them (for 1d3 turns). At level
25 their armor penetration probability is increased by +20%. At
level 32 their dexterity increases by +12. At level 40 they can a
+6 weapon skill rank bonus for all one-handed melee weapon skills. At
level 50 they receive a +20 speed bonus.

Feedback welcome as there is ample time to fine-tune them!
