Warlock Pact damage bugged?

[Celebras]

So, just realized in a EE Thrill on boss that my fey pact ist working as described: This (fey pact) damage is halfed on a successful reflex saving thorw.
I observed, it actually gives no damage. The floating damage says "Save", but nothing else, no half damage? just a visual glitch? or actually not giving the damage?
Btw, when the save was not successful Purple damage with 150-200 not crit.

Fey pact is a reflex save. I believe this Boss has evasion. You might want to try this out on mobs that don't have evasion but have high enough saves to save against your pact damage.

Oh, true. Evasion. Forgot about this. Tx for the insight
