I see what you're saying, I just didn't realize it was a bug and built a toon around that interaction. Power boost doesn't really mention "but it doesn't work if the power also gives resistance". So it feels like a nerf
Could we get some more context on the nerfs to Darkness Affinity Fade? It loses a bit over 10% defense from this change with power boost, which is pretty significant. Other clicky +def powers like Farsight seem to be unchanged. If it's because Fade gives some resistance, I'd rather lose the resistance than the extra defense
