The Giant’s first target is defenses, making them an ideal troop to deploy to get rid of defenses fast. However, due to their low attack damage they are better used in large groups.
Giants prioritize defensive structures above all other targets, and will bypass all other types of enemy buildings and troops while any defenses remain on the battlefield. This is true even if they are under attack by enemy Clan Castletroops, heroes or Skeleton Trap skeletons. Note that like all troops that prioritize defenses, Giants do not consider the Clan Castle to be a defense regardless of whether or not it contains enemy troops, but do consider the defending Grand Warden to be a defensive building. Once all defenses are destroyed, Giants become like any other troop with no preferred target; they will attack the nearest building to them regardless of type, and will turn and attack enemy units if they become aware of any nearby.
Giants have a lot of health but are slow and have low attack power, so use them in groups.
Giants are weak against many defenses grouped together.
You can use Giants as a cheap meat shield while deploying other, higher damaging troops to destroy buildings.
Another strategy is to send many Giants with one or more Healers. Be wary of Air Defenses and other anti-air towers, however, as Healers are very weak and have many vulnerabilities. To counter this it is recommended to place a Giant and Wall Breakers near an Air Defense on the outside to clear the way for Healers.
In general, Giants make better distracting troops than Barbarians due to their much higher health. Because of this they are less vulnerable to Mortar fire and other splash damage, and are much harder to kill.
Giants can be especially susceptible to Spring Traps due to the predictable nature of their AI. Use this to your advantage and place strategic gaps in your Walls with defensive structures behind them, and fill the gaps with one or more Spring Traps.
Giants are reasonably good defensive Clan CastleTroops, as their high health means that multiple offensive units will have to be dispatched to deal with them (a Lightning Spell will not be sufficient). They will also take a relatively long time to kill, delaying the enemy attack. However, the problem with using giants as Clan CastleTroops is that when they come out to defend, they take up five spaces. This means that if the enemy has enough troops to one hit a giant, it will be more efficient to use five Barbarians, as the enemy troops will have to reload. As such, it will take five times as long.
A group of Mortars surrounded by other defenses can spam out a group of Giant's health is seconds. Although sometimes Healing Spells can be used to add the lost health from the Mortars. If the attacker provides Wizards, Goblins or Archers, a Mortar can handle that in ease.
The Giant undergoes significant changes at levels 3 and 6.
At level 1, the Giant wears a brown tunic with a red belt and copper buckle around his waist. He otherwise has no accessories.
At level 3, the Giant gains iron cuffs around his arms and iron knuckles on his hands.
At level 5, the Giant exchanges the dark metal cuffs and knuckles for golden - brass colored ones.
At level 6, the Giant upgrades his cuffs and knuckles to a black metal. He also grows a long, thick red beard and dons a black feather cape.
At level 7, the Giant acquires a golden chestplate underneath its brown tunic that reaches to its shoulders.
At level 8, the Giant acquires golden spikes on both his cuffs and his knuckles.
You can have a maximum of 48 Giants at one time in a complete set of fully upgraded Army Camps. This number increases to 55 if you include the 7 that can fit into a level 6 or higher Clan Castle. On the battlefield, you can clone an additional 16 Giants with two fully upgraded Clone Spells.
The Giant's low damage is visually seen by the attacks with their bare fists.
The Giant's main Barracks image changed substantially as part of the "Witch" update (29 July 2013). However, this change did not affect the look of the in-game unit; when viewed in Army Camps or in battle, the Giant still has the same look as it did prior to the update.
When the Giant attacks a building, a puff of smoke rises from the target.
The Giant is the first of the two Home Village troops in the game that can be upgraded to level 8, highest in the Laboratory. The second is the Wizard.
Since the 2014 Winter Update, the Giant is unlocked at Barracks level 3 instead of level 4. In addition, this update reduced the cost to train Giants of levels 1-5 by 250 elixir.
Of all the Elixir troops, it is the one that deals the least DPS per housing space, with only 11.4 DPS per housing space at max level.
On 11/8/17, low-level Giants could be seen working on buildings as temporary builders, having replaced the Barbarians which in turn replaced the Builders at their job following the latter's departure. In addition to this, when a Builder's Hut was destroyed in battle, a defensive level 1 Giant came out. A week later, on 18th August 2017, the Giants' role as the Builders was taken over by the Witches.
