What is this, anyway? This is Volume L of a series of books which converts every spell we can find from 1st, 2nd, 3.x , and 4th editions, updates and prepares them for use in your 5th Edition game.
Are the spells ready for play? Painstaking effort has been taken to balance each spell for 5th Edition play. The last thing any table needs is overpowered—or underpowered—magic.
What sources were used? It's easier to tell you what didn't find its way into these books. If a spell isn't in here, it's because it's a spell
already released in an official 5e hardback
which duplicates a 5e class/subclass abilities
which has no mechanical impact in 5e, such as those which target alignment
which deal damage not encompassed by 5e's design, such as those impacting ability scores
from Dragon Magazine (because we don't have a complete collection)
This is the 13th volume. NEARLY 300 spells beginning with "M". 57 PAGES FULL OF SPELLS!
