The Seven Deadly Sins: Origin Lancelot Breakthrough Priority Guide

Stop summoning at a single base copy of Lancelot if you only need a functional attacker for open-world exploration and standard campaign progression. If you want him to serve as a primary burst carry in endgame boss fights, aim for breakthrough tier seven, which provides his most cost-effective power spike. Pushing beyond tier seven to maximum breakthrough offers marginal statistical improvements that primarily benefit competitive leaderboard speedruns.

Breakthrough Milestone Overview

The following table outlines the supported investment tiers, resource demands, and target content for Lancelot.

Breakthrough Tier	summoning Cost	Target Content	Performance Profile
Base Copy (0 Duplicates)	Low (1 copy)	Campaign, open world, daily domains	Mechanically complete kit, but relies on longer cooldowns and energy batteries.
Breakthrough 7	High (7 duplicates)	Timed raids, high-tier dungeons, boss encounters	Peak efficiency sweet spot with amplified skill multipliers and faster burst cycling.
Max Breakthrough	Very High (full duplicates)	Competitive leaderboards, high-rank PvP	Luxury stat ceiling with minor rotational gains over tier seven.

Deciding Your Lancelot Summon Target

Use your current summoning budget and progression goals to choose an immediate stopping point:

Stop at Base Copy (0 Duplicates): Choose this if you are free-to-play or building roster diversity. Lancelot's baseline attack strings, mobility, and elemental skill mechanics function without duplicates. In extended boss fights, however, his damage falls off once initial burst windows expire, requiring strict rotation management and higher gear substats to hit critical hit rate and attack targets.
Stop at Breakthrough 7: Choose this if you have saved resources and want Lancelot to headline your endgame teams. Tier seven significantly raises skill multipliers and passive scaling while reducing ability downtime. The extra energy generation lets him cycle burst windows during boss stagger phases without relying on basic attack filler.
Reserve Max Breakthrough for Leaderboards: Avoid pulling past tier seven unless you compete for top clear times. The final duplicate levels grant raw stat padding rather than new rotational mechanics, resulting in diminishing returns per pull compared to earlier tiers.

Adjusting Team Compositions by Breakthrough Level

Lancelot's duplicate tier determines what your supporting teammates must provide during combat rotations:

Base Copy Setup: Slot energy batteries and cooldown-reducing allies alongside Lancelot. Because his un-upgraded kit lacks internal cooldown reduction, dedicated utility supports prevent rotational stalls against high-health targets.
High-Breakthrough Setup (Tier 7 and Above): Replace energy batteries with aggressive damage amplifiers and resistance-shredding debuffers. Because high breakthrough tiers reduce recharge times internally, your rotation should trigger all support buffs immediately before Lancelot takes the field to maximize damage during his shortened burst windows.
