Hitless Sanctum Run + Spiked Exit

Hi there, i'm in the middle of my attempt of a hitless Sanctum run and as you might've guessed stumbled upon the Spiked Exit affliction (5% of current Resolve lost on Room Completion) and was curios if it was an instant run ender -> you take 0.05 dmg and take the smallest dmg possible which would be 1.
Or its free and 0.05 gets rounded down to 0.

Thanks in advance for anyones help

For anyone with the same question, it has been safe to take Spiked Exit during my run.
