• 🎯 A boss turns on whoever hurts it most. A vanilla creeper keeps chasing its first target however hard someone else hits it, and as a boss that left one player to take every blow. Now each player’s damage counts as threat, fading by half every 6 seconds, and a hit from a player whose threat beats that of the boss’s target by a quarter draws the boss to them. An even fight keeps it where it is. aggro in config.yml sets the fade and the margin, or turns it off.
• 🔥 The fire ring burns around every player in the fight, up to four, not only the nearest. It now burns next to grass, flowers, and trees, and on water as flames dancing on it that burn whoever wades through, twice a second unless they have Fire Resistance. Next to anything else that burns, like a house, it still never does. fire_ring_near in abilities.yml turns plants, trees, and water off one by one.
• 🏹 The arrow arc is a ring of arrows in every language, since it flies out all around the boss; an archer’s own aimed volley is the fan that flies at you.
