Should I Kill Arlecchino in Lies of P?

When It Makes Sense

• Good fit: Arlecchino appears as a hostile boss or required roadblock that gates the next Stargazer, shortcut, or story sequence. In that case, killing him is the intended gameplay path and will grant Ergo, a possible boss item, and the freedom to move forward without retracing the same dangerous route.
• Good fit: You have already completed any dialogue, quest, or shop interactions tied to Arlecchino and simply want the unique drop, achievement, or closure that comes from defeating him. If his only remaining value to your run is the loot on his corpse, aggression carries little downside.

When You Should Avoid It

• Warning sign: Arlecchino still functions as a merchant, quest-giver, or source of important lore and item handoffs. Attacking him prematurely can remove access to his stock, fail a side quest, or lock gestures and ending triggers that are easy to miss on a first playthrough.
• Warning sign: The fight is optional and you are under-leveled, short on Star Fragments, or struggling with the area’s other enemies. It is usually safer to mark the location, upgrade your Legion Arm or weapon, and return once the encounter is no longer a resource drain.

Pros and Cons

Pros

• Killing him advances the main path or yields a unique drop, Ergo, or exchangeable boss item that can support your build or unlock crafting options.
• Defeating the threat removes the risk of future ambush or blocked travel and can unlock a nearby Stargazer, making the rest of the area easier to explore.

Cons

• If Arlecchino is connected to a questline or shop, killing him can make related achievements, gestures, or ending conditions permanently unavailable in the current playthrough.
• An optional or difficult fight can consume valuable healing items and Star Fragments without giving you a reward that matches your build, especially if the drop is for a weapon class you do not use.

Decision Checklist

• Have I talked to Arlecchino, checked his shop, and accepted or completed any quests he offers before considering violence?
• Is this encounter required for the main story, or can I leave it for later while I level up, upgrade gear, and gather more Star Fragments?
• Have I backed up my save or consulted a current spoiler-free guide so I understand the exact consequences of killing him in the latest patch?

Alternatives to Consider

If Arlecchino is optional, the safest approach is to complete all visible dialogue and quest steps first, buy anything you might want, and then save before attacking. You can also look for a Specter summon to make the fight less punishing, or simply bypass him and return at a higher level. For players focused on achievements or multiple endings, a second playthrough is often the cleanest way to experience both outcomes.

Final Recommendation

If Arlecchino blocks your path, kill him to progress and claim his rewards. If he is a merchant or quest-giver, exhaust every interaction and purchase first, then back up your save before attacking. Because Lies of P’s quest flags and rewards can shift with updates, confirm the current details in an up-to-date community wiki or guide before making the choice.
