Oh wow, hey thanks for taking the time to submit media to the game!
I was hoping Sampson would be a good introduction to boss battles without making people pull their hair out. I also wanted it to make sense (like Sampson calling for his flock, that's not going to be a common theme in bosses no worries lol)
As for what his "Sampson Phage" SKL equipment does, it's always going to be a skill the enemy has, so to those wondering, you can make a guess based on what the Sampson Phage throws at you. Chapter one should be released by the end of next month.
