I wouldn't call this Noita'd because at that point it's usually not your fault/caused by something you weren't expecting to happen. You fully knew that had a huge blast radius and you only had 50 health which meant you'd get killed very easily and you still chose to use that fireball. you basically detonated a nuke right next to you after having seen a nuke exploding and knowing you would be in range.
This is the moment where you MUST ask yourself: when you get two copies of a perk that gives you 5x spell range, does that combine by addition, or multiplication?
