[color=#000066][b]If a non-permanent Monster effect is activated: You can pay 1000 Life Points OR Tribute one monster you control; The effect becomes permanent. The above effect is only active while you control this face-up card. Pay 500 Life Points at each of your End Phases or banish this card. You cannot target a monster affected by 'Power Saver' with this card.[/b][/color]

[color=#000066][b]When a Monster Trigger effect is activated: You can pay 1000 Life Points OR Tribute one monster you control; The effect becomes a 'Once per turn' effect 'until the End Phase'. The above effect is only active while you control this face-up card. Pay 500 Life Points at each of your End Phases or banish this card.[/b][/color]

[color=#000066][b]Not sure on the wording... For the first, it says effect becomes permanent, but if you don't control that face-up card, the effect reverts back to a non-permanent. For the 2nd, it helps things that only work once (example: when summoned [particular way], or such.).[/b][/color]
