I completed this game in 2 days only.
Here's a pro tip to beat this game fast:
Get the transmute skill and transmute the ingredients, potions etc. At this rate, you will be able to defeat the final boss.
Don't forget to transmute the thief dagger. It's really useful for dropping more items and more gold.
Also, do not forget to use ingredients to craft potions before you face the final boss.
Bonus: Use transmute on Blueberries to get the ultimate potion.
Warning: Only one use of Ultimate potion!
