I will readily admit that this article has potential, but the execution is poor. It honestly has so many grammatical errors in it that they become very distracting. Another reviewer said that it sounds like it was written in another language and run through google translator, and that hit the nail on the head. There are a few mechanics that seem broken as well. The bloodmage ability to drain life doesn't appear to have any sort of cooldown, which is far too powerful. Polish the errors up, tweak a few mechanics, and this would be a much better product.

Lots of reasonable ideas, reads like it was written by a translation app.

The overall feel of the book is very straightforward. Simple formatting, lots of text, no illustrations. It's a $1 product, I understand why there's no art. But it's pretty weird that there are no page numbers, let alone a standard header footer.

The ideas are pretty reasonable. Most of them stem pretty directly from the "bloodlines" in Pathfinder (http://www.d20pfsrd.com/classes/core-classes/sorcerer/bloodlines). In many ways, this feels like a "fill in the blanks" exercise.

Some things are off the chart powerful or possibly unplayable, others are quite ingenious. The "Blood Magic" uses a mechanism that is way too powerful and skips the "spending HD" method that other have used cleanly. The "Ghostly Origin" is either really powerful or impossible to use as a PC. Or maybe both, it's not really clear how it plays out because the wording is so bad.

And the wording is the core reason this book is rated so low. 5E has lots of "boilerplate text" for abilities and this book just tramples all over those boilerplates. Whole paragraphs read like they were written in French and then run through Google Translate with no editors in between.

In some cases this is just annoying:

"At 5th level, you add the fear spell to your sorcerer spells known. Such spells doesn’t count on the number of sorcerer spells known you have."

In other cases this is almost unreadable

As such children grow with its scary companion, its bonds with this creature strengthen and the creatures starts to live inside the children’s body.

Here's a part that just invents a status effect (hassled):

At 1st level, you emanate an aura that let living beings uncomfortable. As an action, you can emanate a 30-feet radius aura that cause discomfort for 1 minute. Any living creature hostile toward you within the area or that enter the area for the first time, must be successful in a Wisdom saving throw or being hassled. A hassled creature suffer disadvantage on attack rolls and ability checks while remain in the aura.

With better editing and some professional polish, this could be a 3 or 4-star rating. But as it stands, there are just too many issues for a dozen pages.

This collection of archetypes is a most welcome addition to the Sorcerer's core options.

The sorcerer has only 2 subclasses in the HB. This PDF is a realy good bonus to give your sorcerers some extra variability
