If you control a "Noble Arms" Equip Spell, you can Special Summon this card (from your hand). You can only Special Summon "Noble Knight Custennin" once per turn this way. A "Noble Knight" monster that was Synchro, Xyz or Link Summoned using this card on the field as material gains this effect.
* If this card is Special Summoned: You can Normal Summon 1 "Noble Knight" monster during your Main Phase this turn, in addition to your Normal Summon/Set (you can only gain this effect once per turn), also, you cannot Special Summon monsters from the Extra Deck for the rest of this turn, except "Noble Knight" monsters.
