Just to work this out, in case anyone is wondering:
Is it worth converting deeds into books, if you have over 50?
- If you keep them as deeds - 48 deeds would be converted into 16 coloured crystals. The remaining 2 would become another coloured crystal, making 17 total. 17 coloured crystals are worth 1,700xp If you have more than 50, the calculation is a little different, and the first 51 deeds would be worth 1,700xp
- If you convert them into books - 1 book is worth 16 coloured crystals. Worth 1,600xp.
So, converting them into books is a net loss. Not a huge one, but still a loss.
EDIT: At 150 deeds, the amount is divisible by 3, so it gives a clearer difference. 150 deeds would convert to 50 coloured crystals. Which would give 5,000xp. 3 books would give 48 coloured crystals. Which would give 4,800xp. Clearly worse off.
