Scribes can craft scrolls that have similar effects to potions and flasks.
The Scrolls are: Agility; Intellect; Protection; Spirit; Stamina; and Strength. They start at level I and run through levels II, III, IV, V, VI, VII, VIII and IX usable by character of level 1, 15, 30, 40, 50, 60, 70, 80 and 85 respectively.
The final scrolls of xxx IX give the users an increase in the relevant ability by 100 for 30 minutes and counts as a battle elixir or gives some other stat increase and counts as a guardian elixir.
They all cost 1 blackfallow ink and 2 resilient parchment to craft 5 at a time. On my server that is 6 gold for five equating to 1.2 gold per scroll.
I sell them at 10 to 15 gold each making a hefty profit.
Sales are slow but regular and i make perhaps 100 to 200 gold per week. Its a low but steady income. Every little helps.
