Thanks to General Scoll's quick thinking and his command that made the combatants subconsciously follow his orders, the Alliance of Kingdoms managed to land a powerful combined attack on the Tribe of Death's forces. Scoll wanted to push the advantage, but he knew that it wouldn't be possible, and he simply watched as the Tribe of Death's forces reacted and responded in kind, either by defending or counter-attacking.
With the waves of attacks going back and forth, the war devolved into complete chaos as all inhibitions were off.
The battle had just begun, and most people were trying to conserve their strength and protect themselves. However, Scoll's command put an end to that as everyone used their full strength during the surprise attack. The Tribe of Death's forces naturally had to do the same if they wanted to defend and survive the attack. And when they counterattacked, it was only obvious that they would use their full strength.
