New to game learning one thing at a time, friends have questions too.
How does weapon Proficiencies work?
Depending on your character class you will have certain weapon proficiencies. For most classes you have proficiency with a category of weapons, like Military Melee. Some classes have specific weapons, etc, but you'll have a list. Certain races might add to that list, like elves have longbow proficiency no matter what class they are.
If you are proficient with a weapon then you get to add the proficiency bonus for that weapon when you use it in combat. This adds to your to-hit roll. Most weapons have +2 proficiency bonus, but some like swords that are more based on skill have a +3.
There are also feats you can take, Weapon Proficiency mainly, that let you get proficiency with additional weapons if you need it.
How do i use my augments points like if it says augment 2 how many points are used?
Augment 2 means you used 2 points. Some augmentable powers allow for several levels of augmentation, in which case you have a choice of how much to spend. Once you reach the end of the encounter and take a short rest your points return.
What is the best human class(friend would like to know)
Humans are good for any class really. It is hard to say that there is one really best choice.
Is shardmind worth making a control wizard?
Shardminds make good wizards in general and they can go with +2 INT/WIS which is what you want for an orb wizard. So, yeah, they're pretty good. The other good choices are Eladrin and Deva.
What is the 1[W] on an atk and it will say 2[W] higher level etc.
The W refers to the damage die type of weapon you are using. Powers with this notation always have the "Weapon" keyword, which means you use them with a weapon of some kind. Usually they're Melee attack powers like say the fighter's Cleave power. So 1[W] means you roll 1 weapon die. If you were using a long sword (1d8 weapon die) then using Cleave you would roll 1d8 for damage when you hit. With Brute Strike (a 3[W] power) you would roll 3d8. Many at-will powers get better at high levels, so Cleave is a 2[W] power at 21st level. This is because you never replace your at-will powers, there are no "higher level" versions (you probably won't use them a ton at high level but you still have the same ones).
They are also way cheap compared to most other solutions. A $20 mat will cover all your needs. If you go for tile sets you'll probably have to spend $100 to have all you need for every occasion.
