Swashbuckle slashes four times and each slash can proc on hit items, so build Diffusal, Basher, or Maelstrom.

Swashbuckle disjoints projectiles at the start, so time the dash to dodge incoming stuns and nukes.

Cast Shield Crash during Swashbuckle for instant AoE damage while keeping your momentum.

Shield Crash grants a damage reduction shield per hero hit, so leap into clusters to get tanky.

Rolling Thunder makes you debuff immune and stuns enemies, so roll through the team to disrupt their fight.

Lucky Shot reduces armor and slows attack speed, so keep swinging to apply the debuff on cores.
