Season 21 Part 2 — new maps, reworked skills and a rebalanced Castle Siege.

Ice Wind Valley - Guide

Ice Wind Valley is a daily guild siege fought inside Devias. Registered guilds fight over a single throne, and the guild whose master sits on it long enough takes the Ice Wind Castle until the next battle. The holder is shown in the sidebar of every page.

LocationDevias — castle area 207,203 - 242,239

How to join

  1. Be a Guild Master. Only the guild master can register the guild.
  2. Between 19:00 and the start of the battle, type /regicewind in game.
  3. Your guild needs at least 1 member and at most 30.
  4. Registration is free.
  5. When the siege starts, registered members are moved to Devias automatically from any map.

How to win

  • Reach the throne inside the castle area and sit on it.
  • Your guild must accumulate 120 seconds of sitting time in total. It does not have to be continuous — if you are killed, the clock keeps what you already earned.
  • If the throne is left empty for more than 60 seconds, the seat is released.
  • After a guild master leaves the throne, a rival master must wait out that same 60-second cooldown before taking the seat — so killing the sitter does not hand you the throne instantly.
  • Guild assistants and ordinary members can also sit, so the guild master is not a single point of failure.
  • Players who did not register are made invisible and cannot interfere with the fight.
  • Entry to Devias 3 is blocked while the siege runs.

Rewards

Who Reward
Winning guild master 5,000 WCoins + 5,000 Goblin Points, a 1 hour buff, and an item from the Ice Wind guild master reward bag.
Winning guild members 1,000 WCoins + 1,000 Goblin Points shared between everyone who took part, a 1 hour buff, and an item from the member reward bag.
Everyone else who fought A 1 hour buff and an item from the participation bag — you get something even if you lose.

Because the member reward is split across everyone who participated, a smaller active guild pays out more per player than a full roster of 30. Winning guild members also carry a flame effect until the next siege.

Tips

  • Register the moment the window opens at 19:00 — it closes when the battle begins.
  • Do not send everyone to the throne. Keep two or three players sitting in rotation and the rest clearing rivals.
  • The 60-second cooldown is the whole game. Time your kill on the sitter so your own master is already standing next to the throne.
  • Total sitting time is cumulative, so short safe sits beat one long risky one.
