He might have been brave, but he wasn't suicidal. Just fighting the newborns of these monsters had pushed him so far that he preferred not to face their parent if possible.
So, as soon as he felt the ground shaking and heard the menacing roar, he dashed in the opposite direction.
Observing his surroundings, he realized he was like a sitting duck between the trees.

Moving his hands as quickly as possible, he climbed.
Despite his left palm being almost useless, he was still able to use it, though sharp pain shot through him with every movement.
Another roar echoed across the field.
It seemed the spider had discovered its offsprings dead, and would undoubtedly begin searching for their killer.
The ground began to shake more violently, prompting Eric to speed up his climb even more.
