How to defeat Professor Harvey in Octopath Traveler 2
The most crucial thing in this combat is using the right weapons and abilities. You must use Throne’s Sixfold strike by equipping an axe to deal maximum damage and take away SP points of the boss.
It is also better to use the AOE damage of Aeber’s Reckoning to inflict damage on the Pure Elementals along with the boss in Octopath 2.
Osvald is crucial in this battle as you can utilize its Elemental attacks to break down the boss. You can use any elemental attacks apart from Dark at the initial stage of the fight. This will ensure the elimination of the boss companions quickly.
You need to use the One True Magic ability of Osvald at the right time. Just wait for Harvey SP to fall to 1, or use it when Osvald is at maximum power. The damage will be severe, and you can end the fight quickly.
You are going to need a lot of SP and BP, so use the restoring abilities of Castti and Partitio. You can use Castti to donate essential resources to your member, ensuring they survive longer and deal maximum damage.
Partitio’s hired help might also turn the tides in your favour, so try using that ability at the right time during the combat with the Octopath Traveler 2 Professor Harvey.
Best party for Professor Harvey
