Esdras watched in glee as the three struggled with all their power against the overwhelming number of hungry goblins.

Bran shouted and a pebble in his hand was shot at several goblins. The pebble might not look like much but it was tough and shot a terrifying speed killing two or more goblins with every shot.
Theo summoned water and launched a small wave at the feet of the goblin making them lose their balance and tripping many behind them.
This gave Tara the perfect chance to shoot wind cutters at them, an arc of condensed wind that was as sharp as a blade, killing and maiming a few at once.
But that was pretty much what they were capable of, besides Bran the two of them were only level 3 apprentices and could only manipulate and produce their respective elements.
