Boss preparation is less about finding one perfect trick and more about removing preventable problems before each attempt.
1. Simplify the loadout
Use equipment you understand. Avoid changing several weapons, spells and consumables at once because it becomes harder to know what actually helped.
2. Enter with a clear recovery plan
Know when and how you can create space to recover. Healing resources only matter if your positioning gives you time to use them.
3. Learn one pattern per attempt
Pick one attack or phase transition to understand. Progress is easier to measure when each failure teaches something specific.
4. Change the real weak point
If the problem is stamina, spacing, survivability or damage uptime, fix that category rather than rebuilding the whole character.
