Is there some sort of pattern I gotta follow to beat the new boss Ophelia? Starting to think on using cheats on this if I get stuck
Ophelia is a tricky one.
I was able to do it by putting the MC in the support position and Terri (The Glades Boss) in the frontline position, then spamming her Shield Stance skill on every turn Ophelia doesn't use Impale. It boosts defense by 1 every time you use it, so eventually, your defense will be high enough that she does minimal damage per turn, allowing you to finally attack without fear of getting destroyed. She can still kill you instantly with Impale, so make sure to guard on the turns where it's coming.
To get a seduction victory on her in the last fight, make sure the MC learned the Shield Stance skill from Terri, then put him on the frontline and Noelle in the support position. Spam Shield Stance every turn except when an Impale is coming, until the MC's defense is high enough to withstand her normal attacks. After that spam lust attacks every turn, and Noelle will help out by randomly doing a chunk of lust damage every few turns. Be sure to still guard during Impales, and eventually you'll get the elusive seduction victory on her.
