You can find the other one I did for Aildyn [here]! If you were to instead face pact commander Aildyn, they would be found in a remote part of Orr. They'd begin the battle with their dual daggers, following the player around and pressuring them with lots of fast attacks. At 75% and 50% Aildyn steps back and lets their pets take over. Their tiger, Achilles, must be taken down to the same level as Aildyn in these sections as Aildyn pesters from afar with their bow and their raven, Cassiopeia, occasionally swoops in for extra damage. At 25% health, AIldyn will summon Achilles again, but stay in the fight themself. Knocking Achilles down to 0 will cause Aildyn to pause and revive him, making themself vulnerable for a few seconds but refilling his health back to 25%. When their break bar appears at 60% and 30%, Aildyn begins to cover the arena in a rain of arrows. The player can either take shelter within the ruins and avoid the attack altogether or can break Aildyns bar with enough CC to stun them briefly, making them vulnerable.
Rhosill's fight would be a hell of a time. It starts off with a jumping puzzle to even reach him, all while he snipes at you from his hiding spot. You have to figure out where he is, and then you have to actually reach him, scaling the cliffs of Drytop before the sniper finishes you off. If you die, he moves, and it starts all over again. Once you reach him, the second phase starts, the brawl. Rhosill appears to mainly fight with their fists, hitting the player with punches, tackles, kicks, and throws. He also however has attacks where he pulls various guns and knives out of his coat for surprise attacks. His break bar can be broken with decent CC to stun him, but when he's stunned, he automatically enters stealth and can only be hit by aoes until he recovers. You aren't allowed to play dirty, only he is. After the initial hell of the jumping puzzle, its a pretty straight forward battle, fill him with damage until he goes down and try to not go down in turn. Rhosill hits hard, but he can only take so much in turn.
