Hard mode

Hard Mode is a new addition that presents each mission and explorable area again on a harder difficulty. It basically adds a much harder version of everything to the existing game. Entering areas in hard mode gives a +50% exp bonus, and completing missions and bonuses contributes to "a Guardian Title Track". If a party is wiped while all party members are at 60% death penalty, the party will be taken back to the last visited outpost.

Hard mode is available in all areas of the game except for Pre-Searing Ascalon.

Accessibility
The Guild Wars Hard Mode Fact Sheet released April 19, 2007 states that in order to access hard mode, the player must have completed a campaign in normal mode, after that all other level 20 characters on the account will gain access to hard mode for that campaign. Hard mode is toggled by switching between two buttons above the party display in an outpost, the Normal Mode button being the standard mission emblem, and Hard mode a stylized red helm.

Monsters

 * Monsters will receive significant adjustments, particularly the monsters which are low-level in regular mode.
 * Gaile Gray stated, "So, if you've ever wanted to explore a version of the Flame Temple Corridor with level 20+ creatures, you'll be able to do that with Hard Mode." Follow the link at the bottom of the page to see her whole statement.
 * Monsters have a 50% attack speed boost, a 50% shortened recharge time of all skills, a 50% run speed increase, and 50% decrease in casting time.
 * All monsters now have Elite Skills.



Items
Hard Mode will introduce new items which will only drop in hard mode. Hard Mode introduced lockpicks, which are similar to keys, but can be used on any locked chests in both modes, and have a chance of not being consumed on use. The chance of them working and the chance of them breaking is determined by your character's level, and Lucky and Treasure Hunter titles.

Other items of interest include tomes, allowing your character learn skills that have been already unlocked on your account. There is an Elite Tome and a Non-Elite Tome for learning elites and non-elites respectively. Passage Scrolls can be used to enter the Underworld or the Fissure of Woe without paying the entry fee. They must be used in the typical entry points for these locations.

Titles
Hard mode added the Guardian and Vanquisher titles, and makes the maximum ranks of the Sunspear and Lightbringer title tracks attainable. Legendary Spearmarshal now requires 50,000 Sunspear points for maximum rank.

Sunspear skills
Although not technically part of Hard Mode, several new Sunspear skills will be added in a future update soon after Hard Mode is released. New profession-specific Sunspear skills will also be added as part of the increased sunspear rankings.

Changes to Normal Mode
When Hard Mode was introduced, the AI of foes in Normal Mode was changed slightly to make it a bit easier. Normal mode monsters now:
 * Take more time to run out of AoE damage.
 * Are less likely to kite for long periods of time.
 * Will, in the case of melee monsters, focus all their attacks on the same target.

The Hard Mode AI is now the most advanced AI ArenaNet has available, and may be improved in the future as ArenaNet finds ways to make the enemies "smarter".

Monster levels in Normal Mode are unchanged. This means that their drop rates are the same as before (though note that drop rates now scale with the size of the party).
