"Summon angel" is tier 3 spell, tier 3 spells is available on lvl 15-21. Summoned monsters is always weaker than caster, or caster wouldn't be able to contron them, so  Archangel of Flame should be level 10-15 or somewhere near that. Death Knight is level 35. So, to summon it you should be at least tier 6 caster specialized in necromancy (Summon&Control), as tier 6 non-necromancer Fluder coudn't control it, we can assume, that "Create middle undead" is tier 7 spell, or higher. Principality of observation was summoned using tier 4 spell. Tier 4 spells  require caster level of 22-28, so it's level should be somewhere around 15-22.
