Arcana
Similar to the standard SOTC skill "Mysteries" but renamed to show its focus in a more magical world. It reflects book knowledge of arcane subjects, "mage sight" and magical perception and is a prerequisite for sorcery. Fiona probably has this as her Apex skill, Bleys likely has it as a high one.
Art
In addition to its mundane uses, it is also the skill used in creation and employment of Trumps. Trump Artists need this skill, and other characters can use it to show how facile they are with Trumps.
Engineering
As per the original skill, but also, given the pre-Industrial society of Amber, also reflects craftsmanship, everything from basket-weaving to blacksmithing.
Medicine
It is mentioned in the Amber novels that most of the Elders, including Gerard, have medical degrees or medical knowledge. This reflects your ability to know Percodan from Pencillin, to set a broken leg, and to recognize things like poisons.
Pattern
In TCOA, your use of the Pattern is a skill. You must have the Blood Of Oberon Aspect (which is free for Amberites) before taking this. Without this skill, the best you can do is shadowwalk slowly and cannot affect probability or any other neat tricks. Random, with his crafty shifting in driving himself and Corwin back to Amber, has this as a high skill. Fiona, with her advanced knowledge backing her up, has it high, too.
Performance
All the world is a stage, and this skill reflects your character's ability with musical instruments, acting, theater and the like. Corwin, known for his ballad, likely has this as a fairly high skill.
Riding
This reflects your character's ability to ride horses, and, possibly, more unusual riding beasts.
Tactics
This reflects your character's knowledge of and ability to apply Military Tactics of various eras and weaponry. This is probably Uncle Benedict's Apex Skill.
Vehicles
Are you comfy with driving cars, flying planes, parasailing, using hovercars, flying a spacecraft and more? This is the skill for you. Random definitely has this as a high level skill.
