Celeste's Radiant Daggers is bugged

[אוֹן]

Celeste's Radiant Dagger says this:




As you can see, it says each stack will grant +11% Spirit Amp. However that does not happen. The +6% Fire Rate does occur, but not the Spirit Amp. Also, why is Spirit Amp modifier with the icon of Spirit Armor?

Here's an example of it in action:

Without any stacks:



With full stacks:



I don't know if I am misunderstanding what it means by Spirit Amp as it is somewhat vague regarding which Spirit attribute it affects but it should either be more obvious or fixed.

The only other explanation is that the Spirit Amp is actually reducing Spirit Armor of the affected enemy? In which case this should make sure to explain it is a Debuff applied to the Target, not a buff to yourself.

After doing more tests, it does indeed seem to increase Damage Dealt, so it is either a description problem or the displayed damage value does not represent the actual Ability Damage multiplied by the Damage Amp. My guess is that each time Spirit Damage is dealt while having stacks, it is actually applying a "one-time Spirit Damage Taken Amplifier debuff" to the enemy through the instance of damage. If this is the case, I have to say it is a very poor design concept and should be changed. Or maybe simply name it Spirit Armor Penetration, and make it a visible attribute.
