Imperius molten armor not hitting stealthed valeera

For some reason Molten armor just flat out doesn’t hit Valeera if she’s stealthed. My memory is foggy, but I’m pretty sure it has hit Nova stealthed. Being unrevealable or not doesn’t seem to be a factor in this.

I’m not very tech savvy so something like this is difficult for me to capture and share with you guys. Sorry for the ambiguity.

Molten Armor would need to be able to target Valeera first. It’s not like Arthas’ Frozen Tempest.

it is not supposed to hit what you can’t see, it doesn’t hit Zagara’s tumors either before they are revealed
