I play a high classed Mage in the world of Achaea. Magi have a range of abilities that make them quite unique to the realm. Be it their ability to rock the battlefield with vibrations or crafting needful magical items that everyone across the realms use. From waterwalking shoes that allow you to well walk across water without hassle to resistance rings that help protect you more thoroughly from the elements. Here's a list of the many great things magi are able to craft.
Worrystone An unpredictable magical item.
Firelash A lash of burning fire.
Hearing Hear while otherwise deaf.
Fist The fist sigil.
Cold Enchant rings with the power to resist cold.
Waterwalking Enchant shoes with the power to walk on water.
Flame The flame sigil.
Electric Enchant rings with electric resistance.
Firewall Create a wall of fire.
Brooch Create a brooch of Thoth.
Key The key sigil.
Eye A sigil dealing with souls and other dimensions.
Augment Increase the power of weapons and armour.
Meteor Turn arrows into flaming meteors.
Magic Enchant rings with magic resistance.
Knife The knife sigil.
Comprehension Understand all mortal languages for a time.
Icewall Create a blocking wall of ice.
Mushroom The mushroom sigil.
Whirlwind The roaring whirlwind of Vastar.
Concealment The obfuscating orb of concealment.
Fire Enchant rings with fire resistance.
Bauble A magically scented bauble to attract falcons.
Monolith The monolith sigil.
Dreamcatcher Increase regeneration while sleeping.
Negation The powerful gem of negation.
Cube The vibration-dampening cube sigil.
Pestilence Create a ring of pestilence.
Stasis Items in the bag of stasis decay more slowly.
Scabbard Enchant a scabbard of stasis.
Orb The chaos-destroying orb sigil.
Purity Create a necklace of purity.
The last item, the Necklace of Purity is Magi only and is unique only to the magi who crafted it. Meaning that only he who created the necklace may wear and use it. They're quite useful for combat as they heal passive afflictions from you. Something also common are sigils. The flame, eye, key, monolith, and fist sigil. Roaming through cities you will see plenty of monoliths to protect from easy entrances or exits from the city.
There are many effective ways to earn and stockpile a bankaccount in achaea, be it credit consumption via other means or hunting vigorously. Or you could pursue the life of a herbalist who harvests plants and sells healing curatives. Magi also fit into this category because they're able to craft some of the most needed and useful items. Meteor arrows always sell at a pretty peny to raiders because it helps add to their range ability. A hefty stack of 100 meteor arrows can easily sell for 10k alone.
The upside to the merchandiser part of the class that the other classes don't hold is the combat. Magi in my opinion is the most complete class in its field when it comes to being able to craft great sellable goods and maintain itself on a battle field among the top combative classes such as monk and occultist. Forestals while having a great means of racking in profit don't fair nearly as well.
I find roaming through the lands that a lot of shop owners are Magi as well, it just makes for good buisness so its not uncommon to see some of the wealthiest people in the realms be also some of the most fierce combatants. Its just another dynamic to the world of Achaea that I love and enjoy. IRE has maintained this stability and advantage/disdavantage system with all its classes.
