In a battle of this level and intensity, it was decided by the fine margins.
Originally, it was universally accepted across the world that same-tiered astral warriors could fight each other to a stalemate most of the times.
The only factors that affect and change this are the different astral techniques and talent.
For Evolvers, it was more or less random, but for mages like Warlocks, their inherent awakened technique determines 90% of their potential as astral warriors.
A Warlock with a deadly combat-oriented technique could beat another Warlock with a less deadly combat-oriented technique any day.
And if they coincidentally meet a Warlock with a non-combat oriented astral technique, it would be a bloodbath unless said Warlock had allies.
The same could not be said for Elementalists.
