You have to "learn" to make each skill individually
Go to Skill Master Ruby in Roumen
Click on the 3rd box, alchemy tab
Find the scroll u want to make, scroll thru the pages with the arrows at the bottom
Buy the skill, and right click to learn it (make sure u close the NPC shop 1st or else u'll sell the skill back to NPC)
They've got some skill naming problems with the Shield Defence scroll, so look for the aqua scroll with 0 experience required
Also, Aim Scroll = Power Scroll.. also a naming problem
