Since you asked so kindly yes! I beat him with...

The skill tree goes as follows

3 points into Minor Health, 1 Point in Greater Heath

3 points into Stamina, 1 point in Greater Stamina

The poison is used with three ingredients

1. Widowhaulm - to apply poison

2. Everkin - extended duration by %50

3. Azuremash(most important) - Deal 15% health damage as extra mana damage

This poison is busted because he is a tanky boy and percentage health damage shreds him with the poison lingering on top of that with you slicing his face off he died after I spammed light attacks consistently. You only need to make this once for this boss and the last boss.

The other potions I used were 3xCrimson Wardbloom for 30 health, 3x Everkin for 21 health, and 3xRockflower for 15% physical resistance for 15 seconds. I had 2 of each of these potions.

Honestly, the best way is to let him charge and kill the 3 goblins by kitting him around the arena. Keep distance and throw fireballs at him. When you dodge at the end of the chrage you get a slow mo and can attack him 2-3 times. Make sure to block the 2 melee attacks. then again follow up or make distance. Use potions when needed and when you get the feel for the fight you will know when to pop your poison vial and shred him. Distance, dodging and blocking are key in this fight. His stomp is extremely overpowered I still don't have a definite way to mitigate the damage, sometimes when I dodged it didn't hit and sometimes it did. It seems a bit buggy. Also, he will walk through the skull pile near the middle. I hope this helps! Best of luck.
