7. The Spellbook System
I made a post about this some time ago and it continues to one of the top 5 posts I have made in terms of number of views.
The spellbook system in B/X in unique among all of the versions of D&D.
It is MY interpretation that:
- Magic-user spellbooks contain a number of spells equal to the number and level of spells the caster may cast in a single day. For example, a 4th level M-U can cast two 1st level spells and two 2nd level spells so their spellbook contains two 1st level and two 2nd level spells.
- There are two ways to acquire new spells: learn them from someone else or spell research.
- Spells may not be copied from scrolls or captured spellbooks into a caster's spellbook.
I really like this system because:
- it results in a de facto specialist system. Each M-U is different.
- it places an importance in finding someone who can teach you the spell that your M-U wants to learn.
- it gives a very prominent role to spell research.
For a little more detail go back to the previous post.
