Level 9 - 11

(Iron Ore >>> Iron, 2 x Coal + 2 x Iron >>> Gun or Copper Ore + Tin Ore >>> Bronze or Copper Ore + Zinc Ore >>> Brass or 2 x Iron + Steel >>> Two-Handed Sword)

Path A

If you are English or Dutch, you can stay in Hamburg and refine metal ores or make Guns from Iron and Coal from the Firearms Production Technique Book to level up to level 11 casting.

Path B

Alternatively, you can smelt Brass from Copper Ore and Zinc Ore in Lübeck

Path C

Portuguese players can use the Lisbon, Porto route to make Bronze from Copper Ore and Tin Ore and then Bell of Withdrawal from the Bronze.

Path D 

Spanish players can travel between Barcelona and Algiers to make Two-Handed Swords from the Weapon Production Technique Book. 

Two-Handed Swords are made from 2 Iron and 1 Steel. Iron can be made from Iron Ore in Algiers. 

Level 11 - 13 

(Iron Ore >>> Iron, Brass + 2 x Iron + 2 x Steel >>> Western Armor or 4 x Coal + 4 x Iron >>> Cannon)

Path A

Spanish players can make Western Armor using the Weapons Production Technique Book from Brass, Iron and Steel. Brass and Steel are available in Barcelona. Iron can be made from Iron Ore in Algiers.

Brass is only available after investment; meaning only Spanish players should make Western Armor to level up.

Path B 

Because other nations don't have access to Brass in Barcelona, they can both go to Dublin or Hamburg and use the Firearms Production Technique Book to make Cannons from Coal and Iron. 

Coal is available in both Hamburg and Dublin. Iron is available in Dublin (Investment 240,000D), and Iron Ore is available in Hamburg which can be turned into Iron with the Book of Metal Refining.

Level 13 - 15

(3 x Gold Dust >>> Gold)

At casting level 13, you can travel to ports in the Caribbean, and purchase Gold Dust. The ports that sell Gold Dust are San Jose, San Diego and Jamaica.

Gold Dust can then be turned into Gold.

Alternative Level 9 - 15 (Ship Cannons)

Another way of leveling up from level 9 casting to level 15 casting is to craft various Ship Cannons for players. The materials for making cannons are generally Cannons, Ammunition and Iron/Steel.

The ingredients for crafting Ship Cannons are all available either by purchase or crafting in the Ports of Barcelona, Hamburg and Dublin. 

Because Barcelona is a Spanish port and close to the trade hub of Lisbon/Seville, it gives Spanish players the natural advantage in crafting Ship Cannons.

Well Good Luck in Casting Leveling.
