How to Beat The Lost Child

[1] Summon Tiel to aid in battle.

Summon Tiel to aid in battle

The player can summon Tiel to assist them if they are not using his Shell. Let him take The Lost Child's aggro while you hack away at its back with heavy attacks. This is also the perfect opportunity to apply status ailments if you can.

[2] Equip a Tarspore to cure or reduce the ill effects of its Excrement Launcher.

Equip a Tarspore

The toxic projectiles expelled by the boss inflicts Poison, making the Tarspore a viable item to negate the status ailment. These can be found in abundance near the Beacon in Outskirts of Nochte.

[3] It gains new attacks after every scripted Riposte.

It gains new attacks

After the first Riposte at 75% HP, the boss gains Inhale & Expel, Forceful Grab, and Sudden Swipe. Below 50% HP, it then gains Overhead Pound and Three-Hit Bite.

[4] Take advantage of its opening near the end of Inhale & Expel.

Take advantage of its opening

The combo takes a while to finish but has an opening that can be exploited. Close the distance as soon as its head turns left to land an attack while it recovers.

[5] Focus on dodging its attacks after the first phase.

Focus on dodging

Once the boss gains Forceful Grab and Brutal Chomp, prioritize evading its attacks and striking only during its recovery, as getting caught can deal enough damage to sever the player from their Shell. A good strategy is to dodge to the right and follow with a counter.

[6] Use appropriate Tarstones to make the fight easier.

The following Tarstones are effective in this fight:

  • Hand of Rock
  • Blackblood Stone
  • Barrage Stone
  • Splitting Stone
