The full grown fallingstar beast was a real challenge for me to learn
At first i tried only physical damage, and it didnt do a lo4 on him,
So than i've tried a couple of times lightning damage, which again, didnt do much.
So i switched to fire damage which was better, but i still didnt like it.
Tried holy damage with the tree sentinel weapon that i got at the start, but found the weapon to be too slow against this beast.
Lastly decided to try the twinblad that i really like and that i have on it poison damage, and with torrent the horse i've managed to beat it.
Crazy fight.
