Build 17 (v0.2.3.0) is an update that was released on February 26, 2014. It has received a hotfix, v0.2.3.4.
The primary focus for the update was the release of Act 2, as well as a substantial revision of the Nightblade mastery (that may have resulted in loss of skill points and/or an invalid skill point assignment).
Added codex page to the quest log window to store collected notes.
Added in-world item comparison tooltips. (Hold Alt and hover over an item on the ground.)
Added "move" keybinding. Press and hold to move to the location of the mouse cursor.
Added "force move" keybinding. Hold to prevent targeting of enemies and objects.
Added gender support for localizations.
Added pet icons for aggressive/normal/defensive states.
Added the world map to the local map UI, which has been resized.
Added a larger minimap toggle to the top right of the screen which displays a larger area.
Components can now be combined regardless of whether you meet the level requirements or not.
Fixed a bug where the hotbar would fail to reload correctly when it contained multiple skills of the same type.
Fixed a bug where skills on the hotbar would fail to work if a component was moved between items.
Fixed a bug where enemies would get up incorrectly after being knocked down.
Fixed a bug where skills which target in an arc would fail to hit additional enemies.
Fixed a bug where monster pets would display incorrect death behavior when the master was killed.
Fixed a bug where NPC quest punctuation would be updated incorrectly.
Fixed a bug where monsters were unable to resummon pets in a timely manner.
Fixed a bug where mouse clicks could be registered by windows behind the skill pick area.
Fixed a bug where pet skills would display incorrect pet stats for the skill level.
Fixed an issue with Physique and Spirit from mastery not granting additional Health/Energy, respectively.
Some one-shot chests have been removed in Act 1.
Rare and Epic drop rates have been improved on bosses and heroes.
Hero spawn rates have been increased.
The experience formula has been adjusted to scale better into the higher levels. You may notice existing characters suddenly gaining a level or two.
You'll now get a small experience bonus for collecting lore objects / notes.
Adjusted mastery life per level to account for fix to physique life bonus. Total life is still a bit higher for each class.
The Strange Key now grants a short quest reminding you to use it. Consequently, this means the key will stop dropping after you open the door. Characters that already opened the door will stop getting more keys to drop if they loot a key.
The Inventor finally received that voice surgery she desperately needed.
Challenge areas: Some side dungeons meant to be especially challenging can now have a level offset, so that they spawn enemies and loot as though the player were higher level. Spawns will still be capped at a min/max for that area if the player is above or below that range. Example: Player is level 20, dungeon has offset of +2, it will spawn enemies and loot as though the player were level 22.
A new hero archetype has been added: Frozen. This type of hero is mostly prevalent in Act 2, though you may encounter it in Act 1 as well.
Nightblade: Slight boost to Shadow Dance's avoid attacks / projectiles and changed +%OA to +%DA.
Nightblade: Increased bleed on Heart Seeker and added %pierce.
Nightblade: There is a new tier 1 melee attack called Lethal Gambit and corresponding tier 4 modifier, Amarasta's Blade Burst. It occupies the space Blade Trap was previously.
Nightblade: Blade Trap now has a radius effect, trapping the target and any adjacent enemies. The new more powerful version has taken Blade Swarm's place.
Nightblade: Blade Swarm removed from mastery to make way for Lethal Gambit. Blade Swarm didn't fit well as it was a little too casterish and also difficult to balance so that it wasn't either useless or outclassed other skills.
Added "auto item tooltips" option. Enables automatically showing item tooltips for in world items.
Removed show loot/filter broken keybind.
Added show item tooltips keybind.
NPC Dialog sounds now use the dialog volume level rather than soundfx volume.
Friendly pets are no longer targetable when not using the target pet keybind.
Fixed a bug where npc merchants could generate the same items.
Fixed a bug where destructibles would drop unseeded items.
Fixed an issue with one-shot chests that would cause them not to drop a guaranteed Epic (this issue was new in the 30+ level range).
Updated epic item loot tables. The level range scaled poorly into the 40's, resulting in level 20 epics dropping from level 45 monsters.
Updated spirit requirements on rings and necklaces, reducing them by 20-30%, particularly at higher levels.
Percent Physique, Cunning, Spirit, Offensive Ability and Defensive Ability bonuses on gear have been reduced.
Absolute Offensive Ability and Defensive Ability on gear has been rebalanced. This primarily affects equipment of level 25 and above.
Removed Offensive Ability affixes from Shield loot tables. With the exception of some uniques, shields will no longer generate Offensive Ability in their stats. This change is not retroactive and only affects drops in B17 and beyond.
Experience formula that determines how much experience is gained from killing enemies has been adjusted to slow down leveling. Based on the results, further adjustment may be required. This change shouldn't affect current character levels.
Fixed an imbalance in the Regenerator hero archetype which caused it to regenerate too fast for most builds to handle.
