The sound of fighting started echoing all around the valley floor as Aberon, Kloud, and Teraria went at each other's throats. Teraria's might, being boosted by Arborea's power, was nothing to laugh at, and although Kloud's fighting prowess was back to his normal power, he wasn't a match.
But what really impressed Astaroth was Aberon's rapidity of casting, even on large-scale spells, but also his battle instincts. The number of times he saved Kloud from getting crushed to death by Teraria was already in the double digits, in barely a minute of combat.
Astaroth had never seen Aberon fight. Not really.
The altercation at the entrance of Tel'narel, he considered a skirmish, at most. But this was an actual combat situation.
One mistake could cascade into premature death. Of course, Aberon's health pool was high enough to prevent him from suddenly dying from a single blow.
