Select caster level:

1st 2nd 3rd 4th 5th 6th 7th 8th 9th 10th 11th 12th 13th 14th 15th 16th 17th 18th 19th 20th

Generates a D&D 5e spellbook based on the wizard class level selected.

The intent is that these can be used as loot so the DM can fairly add spellbooks without giving one character 'what they need'. To that end these spellbooks are generated from survey data and based on how common each spell is in that data, meaning the more people that take a spell the more likely that spell is to show up in this list.

Features:
Generates spells based on how common they are taken by adventurers.
Data is based on 77 submissions.
Simulates gaining spells from level 1 and up. Will never generate an imposible spell book.
When new slots are gained, prefers spells of the maximum level, but has a chance to pick lower level spells.
Your submissions to the survey effect this list. Contribute here: https://goo.gl/a2AOhT
Current restrictions:
It's possible to generate a spellbook with no max-level spells
Will only generate the minimum number of spells per level, (6 + 2 / level above first)
Mechanism for weighing spell selection at each level could be improved with more data.
There's no way to select between battle and utilty spells. This would be easy to do but I need more data.
