The Volcano gives big bonuses.
The four completed monuments. (Promotional picture).

--------------------------------------------------------------
Building monuments requires resources. Each monument has three different types.
The best chances on a resource is by doing tasks related to the theme of the monument. For Riches of Terra it's groud/earth, like gardening or looking on the globe (also baking).
- For Flames of Wisdom it's fire, like baking.
- For Tempest of Bliss it's air, so spraying the bathroom with the new Febreze toilet or catching ghosts.
- For Springs of Fortune it's water, so diving, showering, washing hands, pool actions.
Note: You can get any resource from ANY action! They are rare and few in between, so you have to be patient.
To unlock resources, the cost is 3 LPs for each single resource, so if your level requires 10 resources of one type, it'll cost you 30 LPs to unlock that one. Since there are three types, the total would 90 LPs to unlock them all. Since the requirements increase, so does the cost. Already collected resources are deducted from the LP price, so if you had 2 in the previous example, you'll pay 24 LPs instead of 30 LPs.
Completing all four monuments to level 25 results in unlocking the volcano!
