How to unlock the Patient mage achievement in Heart Box - Definitive Guide
Or you can change the date on your PC and get it much faster. Change the time, open the game, start a level, collect the gift on the right, close the game, and repeat.
You'll probably accumulate quite a few coins as well.
Every consecutive day you log into the game you'll be given a daily reward. To collect it, you must load up a level and you'll see a gift icon on the right side of the screen near the top. Click on it and then you'll be shown all the daily rewards along with where you're at in the progression. You need to log in 16 days in a row to receive the final skin in the this progression.
Be aware that the game doesn't register you logging in that day unless you actually launch the app that day. So if you leave the app running like I typically do, when you go on the next day it won't register unless you close the game app and then open it that day. Only then will you see the gift icon to collect your daily reward.
For the 16 consecutive days, you can either do this legitimately over 16 real life days or you can simply change the date on your Windows 10 device. Collect the daily reward today and then close the game app. Go into your Date and Time settings and set the date forward one day. Open the game, collect your daily reward, and close the app. Repeat for 16 days in a row. Upon collecting the final skin in the progression, this achievement will unlock.
