History of Flawless

Overview

Flawless is the Trials of Osiris seal, introduced in Season of the Worthy. Completing all five seasonal triumphs grants the Flawless title. All required triumphs must be completed within a single season. Roughly four weeks if you go flawless weekly.

Triumphs

• Trials of Osiris: Veteran Disciple - earn trophies from Conquest in Trials of Osiris.
• Confidence Is High - complete a flawless Passage of Confidence during the season.
• Safe Harbor - after visiting the Lighthouse, help another player reach it for the first time.
• Guardian of the Lighthouse (listed as Lighthouse Warrior in the wiki tree) - win 10 matches on a ticket after reaching seven wins.
• This Is the Way - complete a flawless passage on four different maps.

The wiki's requirement list also includes All Roads to Victory, Skill of the One, Strength of the Many and Test Your Mettle; these are not covered by the source I opened and may belong to other seasons' versions of the seal.

Tips

Play with a coordinated team of three and learn map pools; a flawless passage needs seven wins with no losses.

Gilding

A search-result summary of Attack of the Fanboy (page blocked, not opened) says the seal can be gilded by completing five extra Trials triumphs: Lighthouse Warrior, Light for the Lost, Flawless Empyrean, Guardian I Have a Gift for You and Exotic Passage. TheGamePost does not mention gilding. Verify in game.

Rewards
