According to http://uo2.stratics.com/skill-guides/skills-and-professions/spellweaving The duration for GoR is Duration: 30 seconds (+10 seconds per Focus level). 1 minute cooldown. I am unable to test at the moment, but wouldn't this mean GoR can be kept on forever w/ a level 6 focus? 10 seconds per focus level, 60 seconds addition + 30 seconds, and cooldown is only 1 minute. Or does the cooldown begin when the duration begins?
