The skill level of "Crowned Ultimate" is the highest possible attainment in a skill via lessons and/or spending time in Avalon. It is the level beyond Ultimate and it always brings a crowning ability - typically the most potent or important one in the skill.

Once you reach the skill level "Ultimate" you will no longer have to learn lessons - the skill will slowly rise of its own accord every day your character spends time in the land. It is possible to use darsurion enhanced lessons to push quicker to the crowning point but it is uneconomical and only advised if you have progressed all other skills to their maximum and have nothing else to use the lessons on (e..g. training legions).
