🔬 Character & Skill
⚠ Experimental build — one or more skills for this build deal damage based on DEF or HP rather than ATK. The calculator uses the standard ATK-based formula, so results for DEF/HP scaling skills will be inaccurate. HP and DEF scaling formula is under investigation.
🚧 Work in progress — this build is still being tested and verified. Results may not be accurate. Check back for updates.

🔬 Defense Penetration Constant (C) Required

C is a hidden character-specific value that determines how much of your damage gets through enemy armor. It cannot be read from any stat screen — it must be measured from a real hit. Once calibrated, save it for future use. C changes when you unlock new potentials.
You can calibrate C using any skill — pick whichever is easiest to get a clean number from. The C value applies equally to all skills for that character and build.
If a skill shows more than one damage number on screen: add all the numbers from a single hit together and enter the total. For example if you see 1,405 and 1,405 appear from one hit, enter 2,810.
Solve for C below using a real hit, or enter a community-verified value
