The Trident of the seas is a magical staff that requires 75 Magic to wield. It is the only staff, in game, to have a built in combat spell that attacks 20% faster than any other staff. Although the staff has a built-in magic attack, the trident cannot be used against other players in the Wilderness. It can only be used against players within the Castle Wars and TzHaar Fight Pit minigames, as well as the Clan Wars minigame if the clan leaders enable it. The trident cannot be used to autocast any other combat spells.
Tridents are obtained as a rare slayer task drop from cave krakens or krakens with level 87 Slayer. An uncharged trident is dropped by the normal cave krakens, while the boss kraken can drop a fully charged trident. Similar to Barrows equipment, the trident is only tradeable when its either uncharged or fully charged.
The staff can hold up 2,500 charges when fully charged. Charging the staff requires 1 death rune, 1 chaos rune, 5 fire runes and 10 coins per cast, use Trident of the seas on any of these to charge. Both hands must be free in order to charge the weapon. Trident charges can be removed at anytime to recover the runes, however the coins will not be refunded.
Contrary to popular belief, the Trident of the Seas does NOT gain experience at a reduced rate. Unlike regular combat spells, the trident does not reward a base xp for each cast. Instead, players are rewarded experience for each point of damage dealt. The experience gained is 2 exp per damage dealt.
Players with level 59 Crafting can attach a magic fang with to the trident using a chisel, creating a trident of the swamp. This enhances its magic attack bonus, and has the ability to infect a target with venom. However, to take advantage of those benefits requires using Zulrah's scales instead of coins to charge the trident.
The max hit dealt by the trident is dependent on the player's current Magic level. Stat-boost and magic damage bonuses will modify the max hit of the spell. At level 75 magic, the base damage is 20, this increases up to 28 at level 99 (29 if boosted). Likewise, stat-reductions will lower the damage, but the minimum max hit will never fall below 20; even if the player's Magic level is reduced below 75.
Requires 240 Telekinetic, 240 Alchemist, 2400 Enchantment and 240 Graveyard points, and a teacher wand equipped or in the player's inventory, to purchase from the Mage Training Arena. Thus it does not cost much besides the time and runes spent in the Mage Training Arena.
Has a special attack that halves all melee damage the player takes for one minute, which stacks with the PvP damage reduction effect of the Protect from Melee prayer. This consumes 100% of the player's special attack.
When a combat spell is cast with the staff, there is a 1/8 (12.5%) chance that the staff will negate the rune cost for that spell.
Currently the strongest staff when used as a melee weapon, surpassing the Ancient staff and Iban's staff, and provides +17 magic defence.

Has a weapon speed of 6 (same as scimitars/whip), while all other forms of combat magic only have 5 (same as longswords).

Trivia
The trident of the seas is the Oldschool Runescape hybrid equivalent to the Polypore staff and Armadyl Battlestaff from the live game.
The 80 coins per cast of the Iban's staff is only a one time fee. Unless the staff is lost, upon depletion it can be recharged at Iban's well in the Underground Pass free of charge.
