Guild Quest: Co-op Boss Battle Game Online for 2-4 Players

About Guild Quest

Guild Quest is an original cooperative game on this site, inspired by the raid encounters of online role-playing games and reduced to a single fight of about four minutes. Nobody plays against anybody else. The party shares one goal, bringing the boss's health to zero before the boss defeats every hero.

Each player receives a different class at random. The Warrior can shield an ally or Taunt to pull the boss's attack onto a chosen hero. The Mage deals the heaviest damage and can chill the boss to weaken its attacks by a quarter. The Rogue poisons the boss, hits harder while it is debuffed and can make an ally dodge a whole round. The Cleric heals 30 health, blesses an ally for 30 percent more damage and can shield the entire party with Sanctuary.

The key feature is the telegraph. The boss always announces its next attack and its targets one round ahead, so the party can prepare a heal, a shield or a dodge. The boss also changes as it weakens: above two thirds health it strikes the most injured hero, in the middle third it hits two heroes, and below one third it attacks the whole party every round. It suits friends who like planning together.

How to play Guild Quest

1. Work as a team to reduce the boss's health to zero. Everyone wins together or loses together.
2. Each player gets a random class with no duplicates: Warrior, Mage, Rogue or Cleric. Boss health starts at 780 for two heroes and rises by 260 for each extra hero.
3. Every round has a 15-second choose phase. All living heroes pick one ability at the same time, and for heals and buffs also pick which ally receives it.
4. If you do not choose before the countdown ends, your free basic ability is used for you.
5. The round then resolves: hero abilities take effect, poison and other effects are applied, and the boss carries out the attack it announced.
6. The banner shows the boss's next attack and targets one round in advance. Shields, Taunt and Evasive Roll last for a single round.
7. Heroes regain 10 mana each round. A hero reduced to zero health is out for the rest of the fight.
8. The party wins when the boss falls, with the top damage dealer named MVP. The party loses if every hero is defeated or the boss survives 60 rounds.

Guild Quest tips and strategy

• Read the telegraph before choosing. If the boss is about to hit one named hero, a Warrior's Guard Up or a Rogue's Evasive Roll on that hero wastes its whole turn.
• Keep the Cleric's Sanctuary for the final phase. Once the boss is below a third of its health it hits everyone each round, and a 40 percent party shield is worth far more then.
• Have the Rogue apply Poison Blade or the Mage apply Frostbite before the Rogue uses Backstab. The 40 percent bonus needs a debuff on the boss.
• Bless the Mage, not yourself. Thirty percent extra on Arcane Blast and Fireball adds more damage than the same blessing on any other class.
• Use Taunt to protect a hero who is nearly down in the first two phases. The boss picks the lowest-health target, and Taunt redirects that attack to someone who can absorb it.
• Do not let everyone turn defensive. The fight is lost at 60 rounds, so at least half the party should be attacking every round.
