Update - Thursday April 19

Hard Mode
Hard mode has been introduced for the Prophecies, Factions, and Nightfall campaigns. Players who have completed a campaign can now try playing it again in Hard mode for the ultimate challenge. By playing the game in Hard mode, players can find new treasures and earn new titles and rewards.

Now that players can choose their difficulty level, we've adjusted monster AI in Normal mode to present a more moderate challenge. The most advanced and difficult monster behaviors are now reserved for Hard mode. (Note: Certain elite missions may be extremely difficult to complete in Hard mode. We will examine these missions and make any necessary changes at a later date.)


Changes to Normal Mode

The following monster AI modifications have been made to Normal mode only. Monsters in Hard mode continue to use the most challenging AI available.

Monsters in Normal mode now respond more slowly to AoE damage.
Monsters in Normal mode are now less likely to kite for long periods of time.
Melee monsters in Normal mode will once again focus all of their attacks on a single target.

Accessing Hard Mode
To gain access to a campaign's Hard mode, you must win the final mission for that campaign in Normal mode.
Once you win a campaign with any character on your account, every level 20 character on that same account will have access to Hard mode for that campaign.
All Hard mode content is intended for level 20 characters. All monsters are at least level 20, and all henchmen who are below level 20 are automatically promoted to level 20 when taken into Hard mode.

Hard Mode Loot
The average number of uncommon and rare items has been increased in Hard mode.
While in Hard mode, the number of gemstones that players receive from chests after defeating each region of the Domain of Anguish has been doubled.
Elite and non-elite Skill Tomes have been introduced into the game. You can acquire these new items by defeating creatures while in Hard mode.
There is a non-elite Skill Tome that corresponds with each of the ten professions. You may use a Skill Tome to learn any non-elite skill associated with that Tome's correlated profession if that skill is unlocked on your account. Non-elite Skill Tomes may be obtained from any normal creature in Hard mode.
There is an Elite Skill Tome that corresponds with each of the ten professions. You may use a Skill Tome to learn any elite skill associated with that Tome's correlated profession if that skill is unlocked on your account. Elite Skill Tomes may be obtained from any boss creature in Hard mode.

Hard Mode Rewards
Players will receive the following gold, experience, and skill point rewards while in Hard mode:
Prophecies Mission Completion: 500 gold + 2,000 xp + 1 skill point.
Prophecies Bonus Completion: 500 gold + 2,000 xp + 1 skill point.

Factions and Nightfall Expert’s Reward: 300 gold + 2,000 xp + 1 skill point.

Hard Mode Titles

Vanquisher Title
A new Vanquisher title track has been added for Tyria, Cantha, and Elona. These titles will keep track of which explorable areas have been vanquished in a given campaign's Hard mode.
A new Legendary Vanquisher title track has been added. This title keeps track of the number of campaigns a player has successfully vanquished.
Once an explorable area has been vanquished in Hard mode, players will receive gold equal to three times the number of creatures defeated, and experience equal to five times the number of creatures defeated.
Some explorable areas have regions that are blocked off to players until the associated mission has been completed. It is recommended that players complete the mission before trying to vanquish the explorable area of the same name.
In Hard Mode, if all party members of a group are dead and at 60% Death Penalty, they will be returned to the outpost instead of being resurrected.

Guardian Title
A Guardian title track has been added for Tyria, Cantha, and Elona. These titles are the Hard mode version of the existing mission completion titles.
A Legendary Guardian title track has been added. This title keeps track of how many Protector and Guardian titles a player has accumulated throughout Tyria, Cantha, and Elona.

Lockpicks
Your characters can now acquire lockpicks. These new, special items can be found in Hard mode and may also be purchased from any merchant (with the exception of those found in Pre-Searing Ascalon).
The chance to retain a lockpick upon opening a chest is determined by the following formula: (Character level / 2) + (3 * Treasure Hunter ranks) + (2 * Lucky ranks) (%).
In Normal mode, chests have built-in bonuses that make them easier to open than chests in Hard mode.
Lockpicks may be used to open any locked chest in Normal mode, but they are a requirement for opening any chests in Hard mode.
