The noun 'prowess' describes a superior or great skill or ability, a talent, strength or courage; great progress achieved in any field. It also has a specific meaning of bravery, especially in fighting.
So, 'prowess' isn't something a person or thing can 'be'; it is something demonstrated, or achieved. The sentence 'be prowess as always' is grammatically incorrect. Similarly, the following sentences are grammatically incorrect:
'Be kindness, as always.'
'Be sympathy, ...'
'Be success, ...'
You might instead, correctly, say:
'Achieve prowess, as always.'
'Demonstrate prowess, ...'
'Show prowess, ...'
As well, you might qualify the type of prowess you're referring to, as in:
'The children of this family always achieve prowess in everything they study.'
'Those described as heroes are frequently people who've demonstrated prowess in battle or in meeting challenges considered unbeatable.'
'The prowess shown by students here is exceptional, as always.'
'Medals and titles are awarded by many countries to honor the prowess of their military heroes.'
In similar context and using a term other than prowess, you might urge a person or people to:
'Be brave, as always.'
'Be a hero, ...'
'Progress well, ...'
'Be highly successful, ...'
'Be courageous, ...'
Another view:
It is grammatically correct only if it means something like "Let prowess remain as it has been" or "Keep on personifying prowess." Neither of these alternatives makes sense, but at least they are grammatical.
If some other meaning was intended, then it is a sentence fragment, not a complete sentence.
It is 'you are always' and not 'you always' in a sentence for the purposes of correct grammar.
a - he always does it
not always
Yes, but if you write that sentence you need to use proper capitalization. I is always capitalized.

It is not a sentence. There is no main verb.
Yes. There is no word that cannot begin an English sentence. But that does not mean that it is always a good way to begin one.
No, it is not. There is not such thing as "use to". It is always "used to". (with a D). However, with that minor detail it would be. If you were to structure the sentence with the inverted order, it woul read: "That didn't used to be a school." That is a grammatically correct sentence/question.
I suppose you could, but that's not a very grammatically correct sentence. Maybe "Lying is always considered deceitful" but I don't think "a deceit" exists
No. This is incorrect. We always say 'India has".
"You have always been the best" would be more grammatically correct.
"It is Angie and I" is correct. When a sentence is put together this way, "It is ______," you always use the subject form of the pronoun. For example, "It was he who did the dishes" is right. "It is she and I who are going to 'Harry Potter' " is correct. When you get home and walk in the door, it sounds weird but is grammatically right to call out, "It is I!"
The correct sentence is "Your presence and love are always there."
number 1 is correct because it is a complete sentence
It is 'you are always' and not 'you always' in a sentence for the purposes of correct grammar.
"Who sells it?" is correct (always capitalize the first letter of a sentence).
Your presence is always there for me is technically a correct sentence. It might sound better if written "you are always there for me." The addition of "your presence" is redundant.
