Blaze can kill you instant or give other weird effects

When I was in the nether I found a Blaze spawner, but the blaze who came out of that killed me instant, I had full healt max armor but stull i died. This only works for blaze who are spawned from a Blaze spawner in the Nether. Also can Blazes heal your armor ( even without mending ), give you random effects: Enchanted goldenapple affect or wither effect. I haven’t filmed the random effect yet but You will died after the effect instant. This works every time, you have to be patient.
