This skill allows the character to begin to learn the most advanced techniques of Engineering. It is the skill needed to purchase Engineering Levels twenty-one (21) through thirty (30).

The Master can create any Master recipe that they learn and can also use any recipe they may come across in its finished form.

A Master gains three (3) production points for every Level of Engineering they have attained. For example, a Master Engineer with Engineering Level 27 would have eighty-one (81) production points which to create any Apprentice, Journeyman, or Master recipes he or she knows.

This skill will allow the Engineer to know what a written Master recipe is, as well as what the use of any finished product is.

Furthermore, for every level of Engineering a Master has he or she may repair in the field thirty (30) hit or armor points of damage done to a Construct per day. Up to a maximum per day equal to their total. Thus, a Master with Engineering Level 27 could repair up to eight hundred ten (810) points of damage per day. If he or she repaired one set for seven hundred (700) points and another came in down two hundred (200) points the Master could only repair one hundred ten (110) points to that damaged Construct leaving it still down ninety (90) points. Each point of armor repaired this way requires a five (5) count.
