Load npc-300.lua in your lua file, and change the contents of the "transformations" variable (they're NPC IDs). Here's the loading code with the list set to what it currently is. Every entry is equally likely to appear.
local magic = require("npcs/npc-300")
magic.transformations = {54, 112, 33, 185, 301, 165}
