Surtr’s Flames

Surtr’s Flames: Always and Never

The whole guide on one page. The Legion that holds Fire Jotun Surtr at the end wins; everything below serves that.

Always

Chief Hall 24 and a Random Relocator before you enter. See before you enter.
Donate every Frost Tear in preparation. The Team buff ladder and the Team Ranking attack buff come from it. See preparation.
Spend each item on the day it scores most. Yggdrasil Dew, Trap Points and mount items on Day 5; Blessing and Monster Equipment builds, Recast Blades and Enriching Stones on Day 7.
Be in a Battalion. Ruins, their buffs, the Occupation Achievement and your Season Summon count all run through it. See Battalions.
Awaken a Divinity. See Divine Awakening.
Start territory from a Level 1 Town, then build out. See Towns.
Declare war, then break the target in Battle Time. See declaring war.
Kill the Town Marshal first; demolish Sentry Towers.
Do every quest of every Chronicles stage. See Chronicles.
Earn War Merit by killing the enemy's Tier V and higher troops. It sets your Team Reward band.
Be inside the battlefield area when it opens. See the battlefields.
Hold the Ruins to the end. The Occupation Achievement and the Season Summon count what the Battalion holds then.
Empty the Supply Shop and spend Campaign Points before the end.
Log in for the five-day Season Summon after the season. See the Season Summon.

Never

Never use your last Random Relocator before you need to leave. Fixed Relocators do not work in Muspelheim.
Never plan to relocate onto open ground. You can only relocate to valid Tribe Territory.
Never stay on ground the enemy has taken. You can be attacked there.
Never solo a Chainflail Berserker. Only a rally beats it.
Never treat a Ruin as won. Hand, Spine and Mouth are contestable every day, Fire Jotun Surtr every 2 days.
Never confuse the Lv 10 Town with Fire Jotun Surtr.
Never fight your own Legion.
Never read the result table as the win. The holder of Fire Jotun Surtr wins.
Never leave a Chronicles stage with a quest undone.
