A good tip on boss #1:
This's (This is) especially useful for beginners.
This way especially useful for someone it is their first time. This WAY EXTREMELY useful for someone who is very unfamiliar w/ (with) this game & it's (it is) their 1st (first) time playing or not.
"Now when do we get to the tip," you asked?
Well, here it is go to every boss and for the first time see what moves they've (they have).
Then, for the next 3 times try to just counter their moves AMAP (As Much As Possible) or, you can defeat as of even on your VERY first try in your life or any other X (Time).
Then for the next 2 Xs (Times), you try your VERY hardest to counter and do some damage
