Guardian Golem is an optional boss in Elden Ring. It is located in Highroad Cave.
Background[]
A Golem found at the end of Highroad Cave, having most likely fallen down from the bridge to the Divine Tower of Limgrave.
Strategies[]
Damage types: mainly Standard damage, with some Pierce damage from its thrusts and Fire damage from its flame breaths.
It's immune to all Status Effects and has 40% negation to all non-Physical damage types except for Magic, where it has only 20% resistance. It is somewhat weak to Strike damage, having 0% negation towards it, and a mild 10% negation against all other Physical damage types.
Since it starts out lying on the ground and will take a few seconds to get up once alerted, it's easy to get in some opening hits on its ankles. It has the range advantage and can hit most of the cave thanks to the length of its weapon.
The simplest strategy is to do the same as with a regular, non-boss halberd golem by sticking behind its ankles and backing away when its starts hitting the ground with the butt of its weapon or if it breathes fire.
