Herald of Purity + Infernal Legion Bug

I'm currently doing a Minion Instability build which uses Herald of Purity linked with Infernal Legion. I've noticed that sometimes, when the sentinels spawn, they aren't on fire. Without any explanation.

I am also running Cyclone + CwC + Raise Zombie + Infernal Legion and using the Siegebreaker unique belt (Your minions spread caustic ground on death, dealing 20% of their maximum life as chaos damage per second). Consequently, I cannot tell the source of the spawn of HoP ("on kill" from the DoT or on hit of a rare/unique).

It is pretty infrequent, and if I reslot the infernal legion support, they start burning as normal.

Helm, with HoP


Edit: Here's what I mean. I have two active sentinels that are NOT on fire. As I make more, those ones ARE on fire (and explode). I can't figure out what makes these two special. Also, I just realized that those two HoPs didn't have a duration (or had an incredibly long one).

HoP's not on fire, without a duration


Bug Report #

I use skitterbot + Infernal Legion and apparently it has snapshotting

I remove the support gem, the skitterbot still visually burning

Casted skitterbots and then add the support gem, the skitterbot does not visually burning


I think you can test it by turn off herald and then on to see they are back to burning or not.

That isn't unexpected - RF works the same way. Once you have the debuff of being on fire, unslotting it doesn't stop the damage (put in as a way to prevent abuse). I would expect Infernal Legion to function similar to RF for that.

Except that doesn't make sense. If I make 20 sentinels, all on fire and explode, and then the next 2 I make in the same zone are NOT on fire and don't have a duration set, it goes beyond any kind of snapshotting. However, since reslotting the Infernal Legion gem sets them back to being on fire, I would guess that turning HoP off and on again would fix it, if only because the issue is fairly rare itself and that would kill the immortal sentinels I have.

Bumping because this bug has a potential quirk with the new Reaper skill. If the HoP's don't have a duration set, they may be immortal, and may not actually get consumed or have issues getting consumed.
