Forum:Advanced ritual art vs ritual text

ok so in the tips section of "Advanced Ritual Art", http://yugioh.wikia.com/wiki/Card_Tips:Advanced_Ritual_Art it says; Use "Advanced Ritual Art" to summon "Demise, King of Armageddon"/

"Advanced Ritual Art" can be used to send "Left Arm of the Forbidden One", "Left Leg of the Forbidden One", "Right Arm of the Forbidden One" and "Right Leg of the Forbidden One" to the Graveyard to summon "Paladin of White Dragon".

Ritual Summon "Lycanthrope" with "Advanced Ritual Art" by sending six Level 1 Normal Monsters from your deck to the Graveyard. This way you will inflict at least 1200 of damage to your opponent with "Lycanthrope's" effect.

but my question is, all these cards say they can only be ritual summonned with "such and such" ritual spell card, so how can you use advanced ritual art on said monsters? Basically i want to know if i can use advanced ritual art to summon my "Legendary Flame Lord", (by sending my "Dark Magician") when the card text says "This card can only be Ritual Summoned with the Ritual Spell Card, "Incandescent Ordeal""?????

Please help a confused player!
