Royal Ludroth Subspecies is the first Sub fought offline, as it is the Urgent to unlock High-Rank Village quests. Pink Rathian and Qurupeco Sub are fought in 6-Star Village or 3-Star (HR3) Guild. Barroth Sub and Gigginox Sub are fought in 7-Star Village or 4-Star (HR4) Guild. Azure Rathalos, Barioth Sub, Black Diablos, Uragaan Sub and Agnaktor Sub are all fought in 9-Star Village Quests, with Lagiacrus Sub the first of the 4 final Village Urgent Quests. In the Port however, Lagiacrus Sub is fought before to other 5 I mentioned, as it is the Urgent to unlock 5-Star (HR5) Guild Quests, where the others can then be fought. Next is Ceadeus Sub, who is the Urgent to unlock 6-Star (HR6, first G 1-Star quests). Green Plesioth and Dobo Sub are fought at 6-Star quests. At 7-Star (HR7) quests, Jinouga Sub and Narga Sub are fought. Jhen Sub I think is fought after you kill/capture all monsters other than Hungry Jho, the Rare Species, and possibly Alatreon (I'm not sure on that, since I'd already killed it before getting to 8-Star quests.).
