Ravenswatch - OCAID - no items - Carmilla（no melodies）

3/12 Overall, it wasn't too difficult, though I don't think my performance was normal; my route planning was flawed—I was sometimes too care about picking up shards along the way. I feel that finish the challenge came down more to Camilla's ultimate（Mass Punishment） stats and my pre-planned strategy than to any exceptional mechanical skill. My build for this run centered heavily on the Ultimate ability, which accounted for nearly half of my total damage output—a rarity for no items challenge. This was largely due to the generous stat bonuses provided by Camilla's innate talents. Generally speaking, "Impalement" is an outstanding Ultimate (whether compared to Blood lash or those of other characters); it boasts massive dps and a reasonable 60-second cooldown. However, "Blood lash" and the Level 10 "Mass Punishment" (paired with "Cruel Strike") seem tailor-made for the "Claws Nightmare Master" and "BabaYaga" boss fights. That said, a build centered on "Blood Whip" faces certain challenges: 1. "Cruel Strike" is an essential talent; without it, "Blood Whip" is practically useless, and also means you lose out on the massive damage of "Impalement." 2. Before reaching Level 10, the damage output is lackluster against the "Claws Nightmare Master," and the linear attack pattern comes with a significant end-lag. 3. You need to reach Level 10 quickly (ideally without buying XP, so you can save shards to upgrade "Mass Punishment"). I got lucky this run—there were Tumors in all three Acts, which accelerated my progression. This allowed me to reach Level 10 a full two minutes before the Acts 3 boss fight. I took down the "Claws Nightmare Master" even faster than the bosses from Acts 1 and 2—finishing the fight in just two waves. Carmilla is likely the fastest character for taking down this boss. During the "Abomination" and "Skeleton" phases, the "Angel & Demon" mechanic helped me recover a lot of HP. In the final phase against BabaYaga, my strategy was simply to dodge attacks & dealing damage with "Mass Punishment."
