@Rockin Strings Hey I can help you out with that AC bit on your sheets.
Base Armor for everyone is always 10, when you are not wearing armor like full plate or chainmail you can add your dexterity modifier to your armor class.
10+Dexterity Modifier. After that there is armor sets you can wear that can add to the number.
Light Armor: (Adds full Dex Mod)
Padded - 11 (Stealth Disadvantage)
Leather - 11
Studded Leather - 12
Medium Armor: (Only cas have a max of +2 Dex added to your AC)
Hide - 12
Chain shirt -13
Scale mail -14 (Stealth Disadvantage)
Breast plate - 14
Half plate - 15 (Stealth Disadvantage)
Heavy Armor: (You get no Dex modifier with heavy armor and some have strength requirments to wear)
Ring mail - 14 (Stealth disadvantage)
Chain mail - 16 (Stealth disadvantage, STR 14)
Splint - 17 (Stealth disadvantage, STR 15)
Full plate - 18 (Stealth disadvantage, STR 15)
Shields: they just give you a +2 to your AC but you need a free hand to wield one.
Your class also needs to have a proficency in wearing a type of armor like Light, Medium, or Heavy to wear it as well. Fighters for example can wear every type of armor but a Cleric can only used Light, Medium and Shields.
Also Mage not being a class
@Game Maker did make a nice list with short descriptions of every class. A quick list of spell casters are;
Bard
Cleric
Wizard
Warlock
Sorcerer
You can referance them on the first post to get and idea of what they do, the Player Handbook will also have short descriptions on the class pages.
