To spawn Dexiduous The Invincible, you must insert 90-99 Eridium into four totems situated around the Hunter's Grotto. These totems are found as such:
The first totem is to the very west side of the map, on the wooden paths leading up to the large house.
The second is on the east coast, quite obviously stood there.
The third totem is just south of the first, and requires you to jump on top of an elevator on the edge of the cliff. Once the lift reaches its destination head through the small cave and you'll find the totem at the other side of the lake.
The fourth totem is found by going to the south of the lodge and through the narrow path to reach an elevator. Once at the top, simply head north to where the totem is located near the edge of the cliff.
Once all totems have been activated, the final step is to throw the lever located just west of the lodge. The lever requires no additional cost to activate, and once pulled, will begin to spawn waves of increasingly difficult savages. The final wave consists of two Super Badass Witch Doctors and several Badass Savages, and once they are killed, Dexiduous the Invincible will rise from the lake south of the switch.
- Being shot in its bulbous weak spots
The best way to fight Dexiduous is actually through the catch-a-boats, the corrosive one in particular. This is simply because the beast's attacks reach quite far, and the beast himself runs faster than any vault hunter. Just keep scooting around the area, shooting at the beast's weak points to deal huge damage.
In regards to Second Winds, the other drifters in the area make good targets, as do the small camps of savages.
