+Subject: [PATCH] Piglin portal spawn modifier
+
+Allows changing the modifier for the piglin spawn chance from a portal block
+based on the world difficulty.
+
+For example, with the default vanilla value of 2000 there is a 2 out of 2000 chance
+for a piglin to spawn in a portal block each tick in normal mode.
+
+Equation: random.nextInt(modifier) < difficulty
+
+Difficulties:
+0 - peaceful
+1 - easy
+2 - normal
+3 - hard
