At this stage, the information I have been given is:
- Colored Deeds and Imperial Deeds round up to a minimum of 1
- Books of Deeds and Writs round up to the nearest whole number
(did that make any sense to me when I was told.. no)
1 is the next nearest whole number [so] if you have fewer than the 1800 writs to convert to a crystal. We basically give you 1 crystal from 0-1800 writs
So if you had..
- 568 writs
- 1 deed
- 2 imperial deeds
You would come out with 2 Rainbow Crystals and 1 Colored Crystal
