Warlord's Ruin - Wrathbearer Title

• The triumphs you tick, or the whole list with Full Title, completed on your account.
• Dungeon weapons and armor from the clears, with a chance at the exotic sidearm Buried Bloodline.
• Self-play (Sherpa) as an extra.

• Collect the Debts of Kings: finish the dungeon (emblem Shattered Fortress).
• She Stood Alone: finish it solo without leaving the activity.
• Before Your Clans, Mine Thrived: a full fireteam of clanmates.
• Three subclass clears: Carry My Roar Like Thunder for an all-Arc fireteam, Your Fury Burns Bright for all-Solar, and Feast Upon the Gulf for all-Void.
• Show Me Your Prowess: a fireteam of one class.
• Withstand the Siege: Master difficulty (reward Zira's Shell).
• Heed the Whispers: find the Ahamkara bones.

Several of these triumphs raise the starting Buried Bloodline chance in the game data. Fireteam triumphs need three Guardians, so the team supplies the rest of the group where the list asks for one.

• Warlord's Ruin unlocked on your account through its Dungeon Key, which Bungie lists among the keys included in Destiny 2: The Collection.
• A character the team can play the chosen triumphs on.

Which title does the seal give?

Wrathbearer (Warlord's Ruin), shown under your Guardian name once the seal is claimed.
