Galvek

Galvek is the final boss of the Dragon Slayer II quest. It was a dragon incubated by the Dragonkin Zorgoth, who planned to use Galvek to destroy humanity after being imprisoned for ages because he was presumed to be a violent Dragonkin. Zorgoth named this special dragon "Galvek" because it was the Dragonkin word for "Fate".

Galvek was later killed by the player in a prolonged battle. It attempted to launch a final ball of dragonfire at the player, but collapsed before it was able to do so, incinerating its creator instead.

Mechanics
Galvek has 1,200 health and four phases, with each phase consisting of 300 hitpoints each. He uses all three forms of combat, and extremely potent dragonfire which is capable of killing players in one hit if they do not move away from it, regardless of their protection. If next to the tile which was hit by dragonfire, players take half the damage instead.

He can also launch pink dragonfire which disables all prayers upon impact.

Phase I
Galvek stands at the bow of the ship, attacking players with Melee and Magic. He can occasionally launch fire bombs, which if touched (bombs cover a 3x3 radius), will deal an incredible amount of damage, and will very likely instantly kill the player. These fire bombs are always placed in the same position, and will explode after a set amount of time has passed. This phase is common to die in due to players trying to move to avoid his dragonfire attack or moving at the same time Galvek teleports them, resulting in the player running into a bomb and dying.

Phase II
Galvek takes on the powers of air, flying towards the western side of the ship. He can occasionally launch gusts of wind that drain the player's stats by 2 and run energy by 40%. Galvek also begins to use Ranged attacks here and uses his Ranged and Magic attacks at random, similar to Zulrah. This, however, is considered to be the easiest phase.

Phase III
Galvek takes on the powers of water, flying towards the eastern side of the ship. He can occasionally send out tsunami waves (acting much like the Queen Black Dragon's firewalls in RuneScape 3) along with the standard one hit fireball. If hit by these waves, the player will take damage equal to their health. Death is almost inevitable in this phase. Phase III has the potential to be Galvek's deadliest phase, as the player is incredibly limited to movement if Galvek launches his tsunami and his fireball subsequently, leaving almost no room for error. Galvek also uses Ranged attacks much more commonly in this phase.

Phase IV
Galvek takes on the powers of earth, landing on the middle of the ship. He can occasionally launch earth projectiles, which if the player is caught in, will be bound for several seconds. This deals no actual damage to the player, but leaves them extremely vulnerable to the highly damaging dragonfire, which he almost always uses if he is successful in binding the player. His earth attack can be avoided by simply moving one square and walking in circles around Galvek to avoid his rocks and dragonfire allows the player to dodge any binds.
