Is there a certain requirement to get the mentioned mastery above? As i was creating my barbarian the feats available were grappler/firearm specialist.

They dont have prerequisites, but they are not free (found in PHB). If you build your character in a content sharing campaign with someone who has bought the PHB, you do not need to buy it yourself.

So i can,t create a character in D&D beyond with the feats that i want? I would have to manually create using the form?

You can manually create the feats using homebrew tools.

You have to do one of the following:

• Buy the feats or the book containing them
• Be in a campaign with content sharing enabled where another person in the campaign has those feats or the PHB
• Manually enter them into the homebrew system as private homebrew for you to use.

Only the SRD/Basic rules are provided for free. D&D Beyond has to pay Wizards for use of the licensed content, hence why stuff in the hardcovers costs money.

Thanks guys really appreciate it. 

Another question... also wondering... When you create a wizard... How does getting more magics work? I know that as a level 1 i get 4 cantrips and 2 level 1 spells... Does that mean im stuck with those until i manage to buy more cantrips/ level spells? Or when i i level up i just take another two spells frm the dnd beyond character sheet under spells for free?

The wizard's spellcasting feature explains it, but I will simplify it.

Wizards start out knowing 3 cantrips at level 1 and learn 1 more at levels 4 and 10 (max 5).

Their leveled spells first have to be written in their spellbook. Level 1 wizards start with 6 spells in their spellbook and get 2 more for free each time they level up (these spells must be a level equal or lower than your Wizard spell slots). They can also spend time and money to copy spells from scrolls or other books (these don't count against your free spells per level).

Wizards then prepare a number of spells from their spellbook equal to their INT mod + wizard level. You can use spell slots (of equal or higher level) to cast these prepared spells (you can cast the same spell multiple times, it is not used up). You can cast ritual spells as rituals as long as they are in your spellbook, they don't have to be prepared.

Even simplified, it is a lot. Any questions?

Your last statement is correct. Each time you level you get two spells for free (up to a level you can cast) into your spellbook. In addition, you can also copy spells in from scrolls and other spellbooks.

So i guesst is two ways to obtain spells.

1.spend time and money to copy spells from scrolls or other books

2. Every time you level can just add 2 more spells frm the pool of spells at (Add spells frm dnd beyond character list)?

Im just unsure of the second part

That is correct.

Okay thank you guys! Another question, if i have martial weapon and simple weapon under proficiencies does it mean for example

1. Proficient in all martial/simple weapons giving me my proficiency bonus

2. Enables you just to use martial/simple weapon getting no proficiency bonus

If you have proficiency in martial and simple weapons (as a fighter, ranger, and paladin do) you can add your proficiency bonus to attack rolls with them.

You can wield a weapon you are not proficient in, but you don't add your proficiency bonus to hit when you do.

Wait im confuse so lets say under the proficiency and language section on the character sheet it states under weapons (martial weapons,simple weapons)

So do i get the proficiency bonus or it is just saying that i can wield those type of weapons without the bonus

 You add you proficiency bonus to attacks with those weapons (because you are proficient with them).

Nice! Thanks!

Another question is frm forum i read that having great weapon mastery and polearm mastery you are able to get three attacks. Im not sure how that works.

 Polearm mastery lets you make an additional attack as a bonus action, giving you three attacks if you're high enough to have the extra attack feature.
