I'll make sure to take good care of you 
when you run out of mana and can't move.
سأحرص على الاعتناء بك عندما تستنزف

Me divertiré contigo
cuando ya no puedas moverte.
Compte sur moi pour te cajoler

Vou cuidar bem de você quando ficar
sem mana e não conseguir se mover.
Как растеряешь последние капли чар
и упадёшь без сил — я с тобой позабавлюсь.
