Could we get some more details on Ergon Tinctures? At 40,000 bayld, they are prohibitively expensive, and I've only seen one person actually trying it out...
Ergon Tincture (Luminous Isle): INT+12 MND+12 CHR+12 , and it only lasted 60 seconds...
I know they can get stronger with Survey tasks from the Scouts' Coalition, but how much stronger, is the duration the same for all tinctures, etc?
