Free-to-Play Super Break Team
The Trailblazer's role in this free-to-play team is to provide supplemental DMG on a Weakness Broken enemy. March 7th can use her Skill on Gallagher to deal more Toughness DMG on an enemy and have her Super Break DMG increased.
Premium Break Team
The Imaginary Trailblazer works best with characters who rely on the Break Effect stat. A DPS with a high Break Effect stat like Firefly can take advantage of dealing a lot of Super Break DMG if the enemy is Weakness Broken. Ruan Mei can increase the party's Break Effect and Break Efficiency. She can also delay an enemy's recovery from Break, allowing the team to have more chances of dealing Super Break DMG.
Imaginary Debuff Team
This Trailblazer (Imaginary) team comp is viable in certain content where the enemy is weak to Quantum but not to Imaginary. Silver Wolf is a must-have for this team so she can implant an Imaginary Weakness on an enemy. If the enemy is already weak to Imaginary, you can replace Silver Wolf with another debuffer.
Skills
Deals Imaginary DMG equal to #1[i]% of the Trailblazer's ATK to one designated enemy.
Deals Imaginary DMG equal to #1[i]% of the Trailblazer's ATK to one designated enemy target and additionally deals DMG for 4 times, with each time dealing Imaginary DMG equal to #1[i]% of the Trailblazer's ATK to a random enemy.
Grants all allies the Backup Dancer effect, lasting for #1[i] turn(s). This duration decreases by 1 at the start of Trailblazer's every turn. Allies with the Backup Dancer effect have their Break Effect increased by #3[i]%. And when they attack enemy targets that are in the Weakness Broken state, the Toughness Reduction of the attack will be converted into 1 instance of Super Break DMG.
When enemy targets' Toughness is reduced to 0, they will enter the Weakness Break State, which delays their actions.
Super Break DMG increases with higher Break Effect, higher Toughness Reduction of the attack, and higher character levels. Super Break DMG cannot CRIT Hit and is not affected by DMG Boost effects. Super Break DMG is also considered Break DMG.
The Trailblazer immediately regenerates #1[f1] Energy when an enemy target's Weakness is Broken.
After the Technique is used, at the start of the next battle, all allies' Break Effect increases by #1[i]%, lasting for #2[i] turn(s).
