Dinh's bulwark is a two-handed shield created by Dinh, a Lovakengj smith of unparalleled skill. It requires 75 Attack and Defence to wield and is obtained as a rare reward from the Chambers of Xeric.
As the strongest shield in-game (barring any passive effects), it is often equipped alongside magically defensive armour (such as black dragonhide armour) while doing non-combat activities in the Wilderness to defend against player killing and/or dangerous monsters. As a two-handed shield, the bulwark is also capable of attacking opponents. In order to attack with the bulwark, it must be set to the pummel option. This also allows it to perform its special attack.
The animation upon equipping the bulwark.
While the block attack style is active, players lose the ability to attack, but incoming damage is reduced by 20% if not in PvP. There is an 8-tick (4.8 seconds) delay before the damage reduction applies after switching to the bulwark, to prevent players from equipping it on a defence tick and switching back to a more damaging weapon for the attack tick. Furthermore, players wielding the bulwark will not be able to cast any combat spells; players attempting to do so will receive the message "Your bulwark gets in the way". When in defensive mode, the dwarf multicannon will not fire, but it will still rotate, with a filterable message stating "Your bulwark shuns your cowardliness; stopping your cannon from firing."
A player performs the special attack of Dinh's bulwark, Shield Bash
Dinh's bulwark has a special attack, Shield Bash, which hits up to 10 enemies (in both PvM and PvP) in a 11×11 area around the player (thus up to five tiles away from the player) with 20% increased accuracy, consuming 50% of the player's special attack energy. The targeted monster gets hit twice by the attack, while all other monsters get hit once.
This special attack is useful for players in a multicombat area to attack multiple monsters simultaneously to get their attention, such as for dust devils and greater nechryael in the Catacombs of Kourend; as the special attack is considered a melee attack against all affected monsters, it can be useful to use in tandem with the serpentine helm due to its passive chance to inflict venom on hit.
- The special attack of Dinh's bulwark can be used to damage aviansies, which normally cannot be harmed by melee attacks, if used on a nearby ground NPC.
- Despite the special attack description stating that it can hit surrounding enemies in a 10 × 10 area, the actual range is 11 × 11. This is likely an oversight.
- The shield's animation will play when the wielder fails to block an incoming attack. This can alert the wielder to heal as it occurs prior to the hit landing.
