Azmerian Wisp hunting

As far as I can tell, if you kill a rare monster that a wisp was targeting the wisp disappears, even if you haven't discovered / activated the wisp yet, leading to some frustrating moments where you just never see a wisp or you even find it after already killing the monster and see it disappear, actively missing out on loot which doesn't really happen with other special nodes.

I like the wisps which is why I really want something to be done about that, it sucks missing out on them just because you didn't explore the entire map before killing any rares.

AFAIK they only disappear if you have killed all the rares in a map? If you leave 1 rare alive it should target that one.

Regardless, I wish the wisp was something like delirium, where it shows at the start of the map, and follows you to the first rare or something.

On the other hand, stuff like wisps and strongboxes incentivise you to clear the whole map... So idk I'm on the fence.

All of that said, I think it's silly that a talisman is not a guaranteed drop from a wisped rare. Essences are... Why not wisps?

I'd agree with the idea of them being near the start of a map if it weren't for the fact that there could be multiple, recently had a map with three of them through some different means.
