Ignite RF

Hi everyone,

I'm playing a Righteous Fire Chieftain and I'm trying to fully understand how ignite chance and Hinekora, Death’s Fury interact in the current patch (3.24+).

Specifically, I'm confused about:

Does Hinekora's explosion effect require enemies to be ignited?
Some older sources (like older versions of Pohx’s guides) mention needing ignite for the explosions to work properly, but the current tooltip and wiki seem to say it’s just a flat 5% chance on kill — no ignite needed. Can someone confirm?

If I’m not using any skills that can ignite (only RF), is there any point in investing in ignite chance or ignite-related stats (like Combustion Support)?
Since RF itself can’t ignite, I assume these would be wasted — but maybe I’m missing something?

Do ignites help with “chain explosions” or clear speed in any indirect way, even if they’re not required?

Just looking to clear up all the confusion and avoid wasting stats/passives on something that has no effect in my setup. Appreciate any help from people who’ve tested or min-maxed this recently!

Thanks 🙏
