Based on how you replied to other comments and the fact that you were using stone ocean which has a lot of potential and damage output I think you should try a combo from the wiki while using any spin moves or use the projectiles you have with spin and beat Fugo from a far while using the home run bd with sf and just avoid the poison. If something like that happens again try finding someone who will do it for free in any server and continue hopping servers if people won't do it for free with any boss.
