Interested in gaining power as quickly as possible? Then you'll probably want to maximize the amount of experience you get from fighting monsters. This guide will help you get the most stats out of your fights.
Note: This guide is still a work in progress, so not all information has been completely tested yet. If you find something inaccurate or incomplete, please let me know.
Familiars
Note that the volleyball gains are rounded up, so a 25-pound volleyball and a 28-pound volleyball will both give you +7 stat points. The gains are not dependent on the nature of what you're fighting. The cheshire bat and Jill-O-Lantern function like a volleyball. The killer bee will increase your amount of Muscle gained, but less so than for a volleyball.
The hovering sombrero works differently from a volleyball -- rather than giving you a flat increase, the gains from the sombrero depend on the nature of the monster you're fighting. The breakeven point appears to be about 20 XP -- below that level, a volleyball will give you bigger boosts, while above that level, a sombrero is more effective. I'll post more detailed numbers once I work them out. Note that the sombrero will give huge bonuses against enemies in the Sorceress' Tower.
