Reroll vs Refresh Guide

Resource management is one of the most consequential decisions in Build a Blue Lock Squad. Two primary tools for acquiring new characters are the Reroll feature and the Shop Refresh. Understanding when to use each is critical for building a competitive squad without depleting your resources.

What is Reroll?

Reroll is a feature that allows you to reset your entire squad and return all invested resources. When you Reroll, every character you have built up returns to your inventory, but you lose all Experience points, Level progress, and any temporary buffs applied to those characters. Reroll is useful when you realize your squad composition is fundamentally wrong and you need to pivot your entire strategy. The cost of Reroll scales with your squad’s total Level and the number of characters you own.## What is Shop Refresh? Shop Refresh is a smaller-scale resource commitment. Refreshing the shop presents a new set of available characters without affecting your current squad. You keep all your current characters, their levels, and their Chemistry activations. Shop Refresh costs a fixed amount of in-game currency per use. The cost does not scale with your squad size or Level.## Cost Comparison Reroll costs scale with your squad investment. A high-level squad with multiple built characters can cost thousands of resources to Reroll. The benefit is a complete reset that lets you start fresh with a new strategy. Shop Refresh costs a flat rate per refresh. The cumulative cost of multiple Shop Refreshes can eventually exceed the cost of a single Reroll, but you retain your entire squad during the process. The break-even point where multiple Shop Refreshes cost more than one Reroll depends on your current squad Level and size. Use the in-game calculator to compare costs before committing.## When to Reroll Reroll is the correct choice in these scenarios: The meta shifted and your squad is no longer viable. If a balance update fundamentally changes which characters are strong, Reroll lets you pivot completely without keeping dead-weight characters. Your Chemistry build is completely wrong. If you built a squad around incorrect Chemistry assumptions and cannot form viable chains, Reroll is more efficient than slowly replacing individual characters. You pulled a significantly better character that conflicts with your core. If you acquire a character that should be central to your squad but does not fit your current Chemistry setup, a full Reroll may be faster than rebuilding around it.## When to Refresh Shop Refresh is the correct choice in these scenarios: You are improving an already-viable squad. If your current squad is competitive and you are looking to upgrade specific positions, Shop Refresh lets you target those positions without disrupting your core Chemistry chains. You are early in the game. When your squad is low-level, Reroll costs are minimal and Shop Refresh costs are also low. At this stage, Shop Refresh is almost always preferable because you have little to lose by keeping your squad intact. You are farming for a specific character. If your goal is to acquire one particular character, refreshing the shop repeatedly is more resource-efficient than Reroll unless that character fundamentally changes your squad composition.## Refresh Strategies The most efficient Shop Refresh strategy targets specific character pools. The shop displays characters from a rotating pool. Understanding which characters belong to which pool lets you refresh strategically. Characters are organized by rarity and role. If you need a specific striker, refresh during the striker-focused pool rotation. If you need a defensive character, target the defender pool rotation.## Long-Term Resource Planning The optimal approach to resource management balances both tools. Avoid the common mistake of refreshing too many times without ever Rerolding, which accumulates unnecessary costs. Similarly, avoid Rerolling too early, before you have fully explored your current squad’s potential. A good rule of thumb is to attempt five to ten Shop Refreshes before considering a Reroll. If none of those refreshes improve your squad meaningfully, then evaluate whether a Reroll is necessary.## Common Mistakes Refreshing too frequently. Each refresh costs resources that could be saved toward a Reroll. Track your refresh count and set a limit. Rerolling too early. Before Rerolling, confirm that your squad truly cannot work. Many players abandon viable squads prematurely. Ignoring pool rotations. Refreshing during the wrong pool wastes resources. Plan your refreshes around character pool schedules.
