Quote:News: FFXIV ARR Patch 2.4 Dreams of Ice Public Informational Update #1
The boss of the new dungeon Snowcloak will be FENRIR. A glance at the main story as well
Implementation Planned for this Fall
As for Square Enix's MMORPG known as FFXIV:ARR, this fall will mark the opening of the 2.4 update "Dreams of Ice"
Some of this information has already been announced during Tokyo Game Show. There they covered the new class (ROGUE), the new job (NINJA), the three new dungeons and the "Dreams of Ice" continuation of the main story.
Concerning Rogue and Ninja, we've been shown a fragment of the class/job quests. You're invited to make preparations toward the implementation of these new jobs.
ROGUE is a fighter whose weapon skill consists of dual wielding daggers or knives (tanken). They are guards who follow the law of the outlaw. They are the sort of people who restrain those who flee from justice, recover contraband, and distribute wealth to the needy. They were once called "thieves" but they made rebuilt themselves in the pirate city of Limsa Lominsa. They are said to be responsible for the development of the dual-wielding blade technique.
NINJA A long time ago in a land far, far away, the people of the East perfected the art of stealth to protect themselves and their fortunes during troubled times. This art is called ninjutsu. Ninja utilize the energies from the sky, from the bottom of the earth, from that which flows in humankind and create mysterious seals/mudras (in). These mysterious techniques were passed down in secret in scattered, hidden villages in distant lands. That said, if one can master these techniques perhaps one would have the power to change the tides of battle.
As for the three new dungeons, Snowcloak, Sastasha HM and Qarn HM, some information regarding plot synopsis, bosses and mechanics have been released to the public.
Every time there is a brand-new dungeon, the first thing we notice is the boss. For Snowcloak, it has been revealed that this time the boss is Fenrir. For now his particular mechanics are wrapped in mystery, but we know for sure that he shrouds players in ice and freely uses freezing-type attacks.
SNOWCLOAK At dawn of the Seventh Umbral Era, the Calamity caused changes in the climate of Eorzea. Thus the the main road to the Coerthas Western Highlands has been blocked by a huge wall of ice. However, a secret tunnel has been uncovered in the great ice wall that was long thought to be unpassable by foot. What sort of individuals lurk at the end of this tunnel and why?
QARN HM Thanks to the help of adventurers like yourself, the security of the Sunken Temple of Qarn had been guaranteed. Worshipers of Nald'thal and Amajina and Sons Mining Co have formed a joint survey team to undertake a formal excavation of the Sunken Temple. However, after a rumor sprung up that a treasure trove of historic proportions lies in the temple, the ruins have been subjected to tomb robbing and thievery. Hidden from the public eye, magical traps have been carelessly set to catch the robbers. A survey team including the young researcher Nenekko (lalafell) are trapped in the dangerous ruin.
SASTASHA HM Deep inside the Sastasha Seagrot was a hidden dock built by a troupe of former pirates known as the Mistbeard Crew. Once that dock was occupied by a pirate troupe known as the "Seasnake's Tongue", which included Sahagin beastmen, but then the city of Limsa Lominsa took control of it. Then, all of a sudden, a suspicious group of grotesque enemies stormed the secret port by sea. The Yellowjackets that were charged with defending the place scattered about and it has been invaded. Now you must once again recapture the Sastasha Seagrot, and in the process expose the mysterious identity of the invaders.
Lastly, the main story for "Dreams of Ice" continues right where "Defenders of Eorzea" (patch 2.3) left off, including further development of the new organization known as the Crystal Braves. We look forward to the update and the introduction of new characters.
Main Story "Dreams of Ice" "It's all for the sake of Eorzea." ~ That lofty motto was offered up by the organization The Crystal Braves, whose story will be continuing. As pioneers in Eorzean unity, the Crystal Braves will team up with adventurers to pursue the shadows of conspiracy that lurk everywhere from the Ul'dah in the south to Ishgard in the north. What great threats wait there?
