Powers related: The info says dampened/backfiring powers really affect those that assert control over energy, life or over anything. What of death powers and teleportation? Same deal?

Does the magic dampening affect items? Things like mana drives, transgates, summoned weapons, enchanted items, enchanted plushie slowly coming to life due to life powers...?

Character related: Are magical connections between people still intact, or are they also affected by the world?

Most importantly, for Thanatos, does this mean he cannot help Zagreus defy death?
