To unlock this achievement you must collect the 8 paintings hidden in treasures.
There are three types of treasures: those with junk, those of tiki masks, and those of strongboxes.
The paintings are only found in the last ones and only in the treasures that have a strongbox.
The probability that the paintings appear is random and in our case to gather the 8 paintings. We estimate that it will be necessary to open about 70-80 treasures, only from a strongbox.
A fast way to collect the 8 different paintings is to save the world before digging the treasure.
You will be lucky if a painting appears and if it does not appear, load the world and dig the treasure again.
