im messing around with this is single player and im trying to put OP enchantments on it. is there an official ID for the fishing rod? this might be a stupid question.. im just starting to learn command blocks...

You shouldn't need the item ID for enchanting with commands: the command is /enchant <PLAYER> <ENCHANTMENT> <LEVEL>.

But here's the full list of mod item ids:

spawnercraft:mobRod
spawnercraft:mobCage
spawnercraft:mobSpirit
spawnercraft:mobEssence
spawnercraft:mobAgglomeration

When Forge 1.11 comes along, I'll probably update these ids to use snake_case instead of camelCase to fit the Minecraft example.
