It is a building-targeting, melee troop with very high hitpoints and moderate damage that deals death damage when defeated.
Like the Giant, the Golem has extremely high hitpoints and deals significant damage, targeting only buildings (like Crown Towers).
Upon death, the Golem ruptures into two weaker Golemites, causing moderate Area Damage.
The Golemites continue to deal damage until they are destroyed.
Like the Golem, when the Golemites are destroyed, they rupture, dealing low Area Damage.
The Golem's appearance takes form as a colossal, menacing, rock brute with red/turquoise (color depends on the side of the Arena) crystals growing on its back. Its Golemites have a similar look, except much smaller in size.
Upon destruction, the Golem deals area damage and splits into two Golemites. The area damage caused by the troop's destruction deals damage to surrounding enemy cards. This is able to eliminate low health troops like the Skeleton Army and Minion Horde.
The Golemites also deal area damage upon death, but it is insignificant compared to the health of any card.
An effective strategy with the Golem is to strengthen it with supporting troops as it makes its way to the opposing Crown Towers.
By deploying the Golem on the rear of the Arena (behind the player's King's Tower), the player is able to place supportive troops, such as the Wizard, Musketeer or even a Mirrored Golem, to make the push extremely effective and difficult to counter. The Golem is slow, giving the player ample time to build a major push.
However, this costs a heavy amount of Elixir, and it may leave you undefended for an enemy push in the other lane.
Although the Golem spawns Golemites upon death, buildings and troops will start targeting troops behind the Golem since it takes 1 second for the Golemites to spawn and the closest targets will be the troops the Golem is protecting. This can easily be fixed by placing a spell such as Zap, Lightning, Freeze, or an Ice Spirit which can all stun or freeze the tower changing the tower's aim to the Golemites again. You could also back up the Golem push with Electro Wizard, as his lightning bolts stun and will reset the aim of the towers or defending troops onto the Golemites. This also alleviates the Inferno Tower, one of his biggest weaknesses.
Be incredibly careful when playing the Golem. Some opponents will take advantage of the Golem's high Elixir cost and attack the other lane. Easy fixes to this are waiting until the last minute (Elixir is doubled) or to use the Elixir Collector.
Always keep in mind that an Inferno Tower can easily destroy a Golem if allowed to reach its higher damage thresholds.
Although the Skeleton Army is usually effective for countering high hitpoint, single target troops, it is not recommended to use it to counter a Golem because its death damage will kill most, if not all of the Skeletons. However, in desperate situations, the Skeleton Army can still be used to kill the whole Golem, as the Golemites are relatively easy to defeat.

The Golem has the longest deploy time of all troops at 3 seconds.
It is the most expensive Epic card and most expensive single troop in the game, at 8 Elixir.
