on the first day i got in at around 8 30am, then went out at around 9pm, i got 2 sword 3 hats and 3 shields.
yesterday i went in at around 7 am and got dc at around 5pm, i got like 10 crystals but only got 3 shields out of them. its just luck i guess hehe.
i just set an alarm for every 25 mins, and so something else. its frustrating but fun when u get something hehe
