Long Live the Queen
“At first, the now-frequent deadly avalanches in the Coerthas highlands were written off as displays of Oschon's might. That is, until local mountaineers spotted a giant bomb sending smaller explosives up onto the Nail to self-destruct, triggering massive cataracts of snow and rock. Knowing now the true cause of the matter, the Holy See has put a bounty on the floating head of this "bomb queen." The task of regicide, however, will not be an easy one, for she is attended to by a retinue of royal subjects who are ready to serve her in any way necessary─including self-destruction.
— In-game description
Long Live the Queen is a level 35 guildhest introduced in patch 2.0.
Guide
In this guildhest, players will travel through a snowy corridor and face a series of Bomb monsters. The venture culminates into a boss fight with the Queen Bomb. The various Bomb monsters all have different detonating methods.
The guildhest will begin with a wave of adds:
- Votive Candle - Small fire wisps near the entrance.
- Bomb Servitor - an orange bomb that will explode shortly after being aggro'd, KO-ing itself. Due to this, simply avoid its AoE and don't bother attacking it.
- Bomb Charr - a green version of the Bomb Servitor. Just avoid it and don't attack it.
- Red Marshmallow - Slime adds that can inflict
Sleep, but the cast can be interrupted. If a party member gets slept, then they will be unable to dodge the AoEs put out by the other enemies. Healers should be ready with 
Esuna to cleanse off the Sleep. If the healer gets slept and a 
Bard is present, then they should use 
The Warden's Paean to cleanse the healer.
When all adds have been defeated, three dark circles will appear, and the Bomb Queen boss will spawn in the middle circle.
Bomb Queen
Bomb Servitors (orange) and Bomb Charrs (green) will appear like before - avoid their self-destructs, and try not to spend too long attacking them.
This phase also adds Bomb Baronets (black), which will take damage for a while until the Bomb Queen orders them to destruct.
Focus damage on the Bomb Queen instead of the adds, and she should go down quickly. Shortly after she goes down, any remaining bombs will detonate, so be ready to move if necessary.
