Title. How much exp did you gain? How much did you spend? How long did the preparations take you?
Last night I achieved 99 summoning, when at the start I was 91. It cost me 48 mil, and it took me 4800 charms. I spent 10 mil on repairs farming those charms, which took me about 5 days of hard play.
6.3m xp, 58 mil total, 5 day prep.
