Gunnar was a god-like warrior — he is described as nearly invincible in combat. According to Njáls saga, he was a powerful, athletic man "capable of jumping his own height in full body armour, both back and front". He was a skilled archer, and in close combat his weapon of choice was the atgeir, which scholars consider to have been a halberd or glaive of some sort. He was said to have taken this famed weapon in battle from a man named Hallgrímur, while on a Viking raid to the island of Eysýsla (Saaremaa in present-day Estonia - see detailed account on that page).
