Previously, the 5th Development Diary unveiled a glimpse of the cave gameplay by introducing the Ancient Tomb Cave and Spider Cave, this development diary will once again reveal two new cave scenes: the Sandworm Cave and the Plant Cave!

The design of the Sandworm Cavern is intricate and challenging. It is formed by the circular tunnels and numerous interconnected cavities dug out by sandworms, collectively creating a vast underground labyrinth. Navigating this space can easily disorient one, requiring the identification of paths leading to key areas. Fine sand permeates the cavern, with a few rays of sunlight filtering through the cracks in the ceiling. The low, echoing wind whispers through the deep passageways, as if recounting the ancient secrets of the subterranean maze.

The arid environment has given rise to a unique ecosystem, where creatures like beetles, mud wasps, and spiked insects are highly aggressive. They either lie in ambush, disguised, or swarm in packs to attack, making danger often imperceptible. Adventurers must face unpredictable challenges. The Sandworm Boss, the ruler of this ecosystem, poses the greatest threat in the cavern with its massive body and devastating skills. Its appearance signifies not just a fight for survival but also a supreme test of teamwork and operational skills.

The Plant Cavern presents a starkly different ecological setting. Poisonous gases permeate the damp, dark environment, with only sporadic luminescent mushrooms providing faint illumination. Vines hang from the ceiling and along the passageways, while moss covers some of the stones, creating natural decorations that exude an eerie beauty. Every sight within this cavern tells a story of nature's wonders and perils.

This area is home to a variety of bizarre and deadly creatures, including plant mutants with bird-like feet, bloodthirsty tendrils resembling animated vines, and carnivorous flowers with sharp teeth hidden within their massive petals. These dangerous beings lie in wait, becoming obstacles for adventurers. The ruler of the Plant Cavern ecosystem—the Moss Giant—is a colossal figure entirely composed of thick moss, fungi, and rocks. Its movements bring vibrations and a sense of oppression, appearing slow but wielding devastating power. This plant-filled cavern, brimming with toxic gases and life's wonders, awaits the brave souls eager to explore the unknown and challenge their limits.

After this development diary, players should have a deeper understanding of the cave gameplay in the Persia DLC. As a high-difficulty underground area that combines exploration, combat, and survival, the cave gameplay will make the gaming experience full of unknowns and surprises. Stay tuned for more revelations on the Persia DLC.
