Compared with the warrior helm (also requiring 45 Defence but not the completion of The Fremennik Trialsquest), the warrior helm solely provides an attack bonus to slash (+5), whereas the Fighter hat also provides attack bonuses to stab (+5) and crush (+5). Compared to the Berserker helm that has no melee attack bonuses at all, the Fighter hat provides a superior melee attack bonus (+5 to all) but lacks the strength bonus (+3) provided by the Berserker helm. The fighter hat is a popular choice among pures who prefer it over the Berserker helm.
If the player dies below level 20 Wilderness, it will remain in the player's inventory. However, the item will be unusable and must be repaired with 45,000 coins by using the item on Perdu.
