If you control a monster whose original name is "The Winged Dragon of Ra", you can activate this card the turn it was Set. During the Main Phase: You can pay LP so that you only have 100 left; 1 Special Summoned "The Winged Dragon of Ra" you control gains ATK/DEF equal to the amount of LP paid (even if this card leaves the field). Once per turn: You can Tribute 1 "The Winged Dragon of Ra"; gain LP equal to its ATK on the field. You cannot activate both of this card's effects in the same Chain.
