I thought a maxed gold chest finder with a maxxed out bar from combat guaranteed a gold chest but i have spent 3 hours in fights with a gold chest finder and a maxxed bar and cant get a gold chest to spawn. I have found about 20 wooden chests, fought who knows how many times since the bar got filled used 3 energy 2 potions 4 magic 1 potions and 2 magic 2 potions and still not 1 gold chest. Im in the cave just before the lava area not sure if its bugged or the max is just a 1% chance to find a gold chest but im getting frustrated in the extreme here.
When the Gold treasure finder is maxed (100%, the chances increases to obtaining a gold chest.
Every time this happens, the meter will change from yellow to red. To keep the meter up, you must use energy potions to stay awake.
The best method for farming treasures is to let Nel do that for you. As you level up her relationship, she will provide additional help.
