I run around the half-elf, closing the distance, strike with a naginata, grab him by the throat, and knee him in the solar plexus...

It didn't help much; not that much health was lost, but the demon lost a lot. Now is the time to shout for dragons and everyone else who is here! A battle cry that is understood by all the children of Silanna, calling fire upon ourselves, echoes through the forest, and everyone nearby starts firing at the demon. Only relatively high luck, compared to the demon, helps to avoid being hit by arrows, spears, horns, swords... The demon must die! Or retreat! I find my sword, take it in my hand, kill one archdevil, already quite wounded, and hurry to get out of the mass bloodshed. Oh yes, I'll add the demon to my list of sworn enemies; he won't give up! Even his magic won't save him now! Thank you, Silanna! The land we walk on and the forests we live in are our home; we must protect it!!!!!
CAN ANYONE TELL ME HOW DAMAGE IS DETERMINED? ACCORDING TO MY CALCULATIONS, WE SHOULD HAVE DIED A LONG TIME AGO!!!!!!
