Now for a little statistical gymnastics
240 gems = 30000 gold = 100 gold keys
Expected yield from 100 gold keys:
46 common
18 rare
18 minor
9 major
9 other
commons are worth 5 souls
rares are worth 10 souls
The others we can assume 3 are 20 glory each, 3 are 30 souls each, and 3 are 500 gold each.
From rewards purchases we know that 25 glory = 40 souls, so 320 = 60 glory is worth 96 souls.
Using the above purchase we can associate 30000 gold with 240 gems, so 3500 = 1500 gold = 12 gems
240 gems =
46 common = 46* 5 = 230 souls
18 rare = 18*10 = 180 souls
18 minor
9 major
3 gold other = 1500 gold = 12 gems
3 soul other = 90 souls
3 glory other = 60 glory = 96 souls
Combining the soul entries:
240 gems =
596 souls
18 minor
9 major
12 gems
At the best ratio, 900 gems = 9000 souls, so 596 souls is about 60 gems
240 gems =
60 gems
18 minor
9 major
12 gems
And subtracting 72 gems from both sides
168 gems = 18 minor + 9 major
If majors are worth twice a minor (the choice I’d make), then 1 minor = 5 gems.
Alternately using the other extreme, of 5 souls per gem, the 596 souls = 119 gems:
240 gems =
119 gems
18 minor
9 major
12 gems
And subtracting 131 gems from both sides
109 gems = 18 minor + 9 major
If majors are worth twice a minor (the choice I’d make), then 1 minor = 3 gems.
So why do all this? Because I’d like to suggest a “Minor Traitstone Pack”, 1 of each type for 20 gems (between 18 if 3 gems / stone and 30 if 5 gems /stone)
