Going over to where Lex stood in front of a Suit of Armour Tag gave her a small nod. Could he use this rune on himself? In case Lex wanted to have another go at him? Maybe he should ask Professor after class. Though, he thought, that, if this were possible, it would hurt incredibly bad and probably cut out his skin. So, maybe not.

"Hey Lex! Can I help?" He asked, though he gave her no choice to answer because the boy was already moving to the backside of the Suit of Armour and pointing his wand at it. "Intaglio Algiz! Intaglio Algiz! Intaglio Algiz! Intaglio Algiz!" Tag said the last one for extra measure. He usually only used three. With him and Lex working on this suit of armour it'd be more stronger protected.
