Just incase people haven't worked it out or if your maths isn't up to scratch, here is the best way to level it up.
Pretty simple really.
If you are actively playing then do the following.
Choose the smallest amount of time duration because that gives the most EXP and the most Points.
At the moment i have 30 mins as min and 360 mins as max and for the 30 mins i get 450EXP / 6 Antiquity Points compared to 360 mins which gives 3240EXP / 43 Points.
Now here is the maths part.... There are 12 30 mins in a 360min total. so 12 x 450 = 5400 and 12 x 6 = 72
So that is 5400EXP / 72 Points. That is 2260EXP more and 25 Antiquity Points more.
So if you're actively playing, that is the best way to level. If you're afk then obviously just choose the max time and go and watch cat videos lol.
Hope this was useful.
