Keep or Reroll?
Keep Thunder. It is a S-tier element and a top choice for Crit and boss damage. Rerolling away from it is rarely worth the risk.
Why Thunder is Worth Keeping
Thunder is the best element in Broken Blade. Its +50% Crit Damage effect is unmatched for endgame damage output. No other element provides the same level of scaling with crit-focused builds. If you roll Thunder, stop rerolling and build around it. The only reason to consider rerolling would be if your build has zero crit chance, which is an unusual situation since many races and blessings provide crit.
Best Weapon Types for Thunder
Thunder pairs best with Buster and Dragon Slayer for maximum crit damage on slow, heavy hits. It also works well with Sword builds that use the Excalibur line. Katana can benefit from Thunder but relies on stacking crit chance from other sources first.
Thunder in Boss Rush
Thunder is the top element for Boss Rush. The +50% Crit Damage bonus directly increases your clear speed and damage output, which is critical for efficient Boss Rush farming. Every top Boss Rush build uses Thunder as its element of choice.
Beginner Value
Thunder is excellent right from the start. Its damage bonuses make early leveling faster and boss fights smoother. You can comfortably invest in builds around it.
Late-game Value
Thunder is the best element for endgame content. Its stat bonuses scale extremely well with max-level gear and are a core part of the highest DPS builds.
At max level with fully upgraded gear, Thunder becomes even more valuable. As your crit chance increases from race bonuses (like Aesir) and blessing effects, the +50% Crit Damage multiplier compounds with your other stats. This is why Thunder is considered the best element — it scales multiplicatively with gear rather than additively.
