-1 Money and equipmen (1/2)
-- MONEY --
1 big gold coin =>50 gold coins
1 gold coin => 20 silver coins
1 silver coin => 10 big copper coins => 100 little copper coins
When gold isn't enough, precious gems or rare materials can be used to exchange.
-- EQUIPMENT --
Most of the existing equipment is pretty basic, armour made of leather (simple, studded, reinforced with bits of metal...) and weapons forged with iron or steel alloy.
Anything better needs to go through the hands of master craftsmen capable of magic, usually followers of Nyx, Theomars or Monte. These experts are capable of creating new alloys, engraving magic circuits and infusing materials with their power to give their creations unique capacities.
Broke elementalists can exhaust themselves in order to create elemental crystals and sell them, which are then used in alchemy and crafting.
tl:dr
BASIC : leather / iron / steel works.
