The Henne Mines is a location in the land of Ivalice in Final Fantasy XII. It is an underground magicite mine explored by the Archadian Empire. At first only the Phase 1 site and dig are accessible, however after defeating at least 10 Espers, the Garif Geomancer will open up the gate to Phase 2 where the enemies become much tougher and the Esper Zodiark can be located, fought, and obtained if defeated. Phase 2 can be accessed from the Feywood, but only a small portion is accessible. The rest of it will be blocked off by a mine cart until the Esper Zodiark is defeated. When accessing Phase 2 it is recommended that you wait until your party's average level is above level 70.
The Henne Mines are located just to the southwest of Jahara, and at first are only accessible via Chocobo through the Ozmone Plains. Phase 2 is also accessible through the Feywood, but only a portion of the Phase 2 Shaft. The rest of Phase 2 is blocked off unless you complete the Mindflayer clan hunt, obtain 10 Espers, and speak to the Garif Geomancer in Jahara. He will open the east gate in the Ore Separation section. It is recommended that your character's levels are extremely high and above level 70 at least, because there are monsters that are much tougher.
Ironically, there is a location in the mines that is an excellent spot to level up. At "Pithead Junction C" is a switch that spawns a dozen or more Abysteels when pressed. Abysteels are undead and vulnerable to Sleep, so with the correct Gambit set-ups involving Curaja and Sleepga, they can be killed quickly and with minimal difficulties. Walking two screens away and returning will cause them to respawn when the switch is pressed again. The Abysteels will leave roughly 3,000 EXP each, which in tandem with their large numbers makes leveling quick and easy. If the party is equipped with "Embroidered Tippets", they could potentially earn upwards of 100,000 EXP with each press of the switch.
Henne Mines is renowned for two convenient grinding spots. The first is "Pithead Junction B." which is closer to the orange Gate Crystal. After touching the gate switch in the room, a limited number of Jellies fall from above, and if they die from the Time Magick Break, they will respawn endlessly. If player programs their Gambits correctly, it is possible to sustain an auto-leveling without touching the controller. Besides the Break spell, it is recommended to have another ally to cast Sleepga on the Jellies and another one prepares curative spells to keep the party alive.
The second spot is "Pithead Junction C." It is quite far from the Gate Crystal and riskier than in "Pithead Junction B". After flipping the gate switch Abysteels will appear. They do not respawn like the Jellies are are vulnerable to Sleep, and are damaged by curative magic. With the proper gambit set-up, the player can use Sleepga and Curaja to neutralize the Abysteels and kill them via Curaja without waking them up. The Abysteels are much stronger than the jellies but yield a great deal more Exp. Once all the Abysteels are slain, the player must move two areas away and return to spawn more when the switch is flipped again.
