Rime-Coat raiment has two separate issues. Firstly, the crystals generated by it cause devour to stop activating from their shatter kills about 50% of the time. Here's an example of this occuring: https://youtu.be/nkf09ROTIHY Additionally, if you have Bleak Domain stacks, and you have a weapon with projectile velocity, like glaives, it will stop their on-hit/on-kill weapon perks from activating almost every time. Here's an example of this occurring (the glaive has demolitionist and chain reaction, you can see in the final kill of the video), as well as an example of it working as intended with a hitscan weapon: https://youtu.be/Vy2GPuY1PNY Just from my observations, this bug seems to be because the rimecoat icicles are hitting the enemy before glaive projectiles do. However, this occurs even in higher-level content where the icicle will not one-shot an enemy, meaning if the icicle hits any time before the glaive will, it will nullify the glaive kill. I've been posting about this since the release of episode revenant, and got a reply from a bungiehelp account about 2 months ago, telling me to watch known issues for a status, but it's still not on the known issues page.
