The illager stone holder

If you add this, on the last wave of a raid you will get the illager stone holder riding on a ravager as the final ‘boss.’ He drops the illager stone, when held gives you the ‘hero of the village’ effect. When combined with a flint and steel, you get a portal lighter, which is the only way to light a nether portal. This makes the illager stone holder the boss of the overworld, and gives raids more point, besides the loot dropped by the illagers. Also, the portal lighter has infinite durability, so you only need to fight one raid. If you want to make access to the nether easier than this, make all the captains drop illager stones too. But then the raids would still be pointless....
