Kill Soldier of Godrick bare fist only
To mark this square, you must defeat Soldier of Godrick, the tutorial boss in the Cave of Knowledge, using only bare fists without armament.
As the damage from bare fists is shockingly low, this square takes a few minutes for completion, even if you have more Strength. You can perform backstabs on the boss, but not parries.
There is synergy with Complete 3 Caves and Kill 4 Bosses with the word 'God' in it.
Soldier of Godrick counts as a Limgrave/Weeping Peninsula boss.
