Every time when player do a summon on heroes or equipment l, summon meter gauge will be filled/increase.
For example if I do 1x10 summons which is 400gems, 400 would be added to the meter gauge.
Maybe could do these prizes exchange limit to once a month. Like a cooldown.
Just a suggestion/rough guide.
