3D's of Adventuring Player's Guidebook to the Multiverse Plane Test Packet Update 9

The first two levels of magic-user is now completely playtest able, there is now enough cantrips and 1st level magic-user spells to choose your starting set and still be able to get a new one when you level up to 2nd. This is the first completely playtest able class since the fighter and thief which have been completely function since 2016. The Cleric needs a couple of domains created with the 1st and 2nd level spells for them and the deities special spell completed before that class is completely playtest able and the bard need only more 1st level spells. I'm still working on my redesign of the Psionicist which is still giving me some troubles. Out of the six core class, Bard, Cleric, Fighter, Magic-user, Psionicist, and Thief half are fully functioning now (at least for the 1st and 2nd level in the magic-user's case and all the way to 20+ for the fighter and thief). Here is a complete list of changes.

Player's Guide book

- Added Cantrips:  dry, dampen, exterminate, firefinger, and grope.

- Added 1st level spells:  Armor, Burning Hands, Dancing Lights, and Shocking grasp.

- Added Helms to the list of purchasable armor. This is important for a new mechanic.

- Added a mechanic to allow creatures to aim at the heads of enemies called aimed attack rolls. Your head now has an armor class value separate from your own.

- Altered the time it takes to perform a reaction action from 1/4th a segment (2 seconds) to 1/6th a segment (1 second). This is for the benefit of cantrips reflecting their simple quick verbal and somatic components, though some can be used as a free or swift action.

- Fixed a inconsistency with saving throws description for spells. Enlarge said saving throws, while all other spells said save throw. It has now been changed so all spells say saving throws. 

- Fixed some minor formatting issues.

Monsters of the Multiverse

- Fixed some missing text in the description of magic resistance to make it read more clear in what it does and how it functions.
