Player notes
Xavier is a Legendary Breaker tagged with Iria, SoC. In practical terms they cover anti-tank physical pressure and frontline shred. Support debuffer with knockback and tempo tools rather than a pure DPS carry.
Do not force as main DPS. Apply rare debuffs, create space, and set up real damage dealers.
In the role triangle, lean on free damage into Defenders and respect Seekers. Stars and gear still matter more than matchup alone on hard maps.
Star plan on this page (“See guide”) is a budgeting hint: finish the first power spike that stabilizes clears, then reassess against your enabler and main carry before dumping every shard here.

Gear deep dive
- Weapon — Maverick's Cloak: Assassin trinket for dodge/crit roamers. Prefer it when carries who fight away from the main blob.
- Trinket — Focus Lens: Crit lens for physical carries mid-game. Best when universal crit budget piece — highest build count in the DB.
- Tarot — Temperance: Balanced mid-game tarot for flexible builds. Take it for flexible mid-game tarot when bis is missing — very high build count.

Team plan
Open Xavier into Defender-heavy packs. Bring a Watcher for uptime and a Seeker or Destroyer flex if the map punishes pure physical lines.
- Open with Falling Comet Dash Combat Frenzy Spear when the board allows a clean cast.
- Keep reaction (Vanguard) online—do not strip it for vanity actives mid-fight.
- Basic attack (Charged Attack Indomitable Spirit Daring) is for reposition turns or when NRG is dry.
- Count kill thresholds before committing—wasted openers cost the Act Again or NRG window.
