The most easy way to go through the game quickly is to buy the Premium Pack, this comes with:

Ring of Might (Strength Boost)
Fortune Medallion (Double Dropped Gold)
Sprint Boots (Increase Walking Speed)
Arcane Pin (Magic Boost)
Ice Shoes (Prevents Slipping on Ice)
Boomerang (Ranged, High Damage, Chance to Stun)
Skull Pixie Egg (Supporter Monster, 30 mins to hatch)

[Note] All equipable items besides the Boomerang and Skull Pixie can all be worn at once, along with other items.(Meaning you could be wearing the Sprint boots, the Ice Shoes, and feet armor all at once)

While most of you don't want to spend $2 for Premium. It is really helpful.

[Non-Premium]

-Buy the best armor, it will help you to not die.

-Buy the best weapon. [You have to choose what "Class" you will be]
