Fire giant

Fire giants are large powerful giants that are well known for their excellent combat and Slayer experience. Like most giants, they can hit hard, up to 11, have high hitpoints, and have low defence. This monster is classified as a large monster and as such the dragon halberd special attack hits it twice.

Locations comparison
The Waterfall Dungeon is the ideal area to range or mage Fire Giants. You must have completed the Waterfall Quest to enter this dungeon, and you must have Glarial's amulet in your inventory when entering the waterfall. Most fire giants in the Waterfall Dungeon appear in the centre room. While the fire giants are aggressive it is best to stand by the large door in the southern part of the room, on the eastern tile. Once the fire giants stop auto-attacking you, you are free to roam the room and range or mage across the table. You will need to perform this process again if you are teleported by a random event (for example the Maze or Evil Bob).

For the western part of the dungeon there are less spawns but arguably better safe spots. One of them is to go to the northern side of the room next to the door. With the passage so narrow it is impossible for them to attack you; however, certain Fire Giants attacked from this spot may become unagressive whilst being attacked, and wander away, meaning you have to move to continue killing it - leaving you vulnerable to other giants or the one you are killing (when it begins to attack you again). Another one is between the chair and the rock. Yet another is between the rock and the walls (both sides). There may be a shadow spider there so you may have to wait for them to become tolerant.

It is possible for rangers and mages to stay in this area for an extended period of time. Bring plenty of nature runes to high level alchemy items such as the mithril square shield, fire battlestaff, rune scimitar etc. Bring a chisel to cut gems, and clean herbs before you drop them (for experience in crafting and herblore). It is possible to deposit items in your bank when you get the Gravedigger random event.

In the Smoke dungeon, or Brimhaven Dungeon there are few safespots. Although the Waterfall Dungeon is possibly the safest place to range or mage them, it is often quite crowded there. The Smokey Well Dungeon is usually the least crowded.

Fire giants are rangeable in the Wilderness dungeon, but the area is located in very deep Wilderness (level 50), meaning players can't teleport, and revenants are known to patrol the dungeon as well.

In the Chaos Tunnels they attack in groups, so it's best to come prepared with food and armour. One group is located near the middle southern rift entrance located just east of the Mage of Zamorak north of Edgeville. They are located just west of the Giant rock crabs through the north-western portal. A second group is located directly north of the Giant rock crabs, however you must go via the eastern Fire Giants and then through a group of ZMI members.

Trivia
Before the graphical updates, the Fire Giants' weapon was often thought to be a dragon two-hander (this was before the release of the actual weapon). This was said to be true in a Postbag from the Hedge. The letter read:

"Why is it that you got the only dragon two hander in the game, and you don't even drop it....."

The Fire Giant replied:

"If you had the only dragon two-hander in the game, would you drop it?"
