Build 13 (v0.1.9.7) is an update that was released on October 18, 2013[1]. It has received a hotfix, v0.1.9.9[2].
Among other changes, this update introduced the Nightblade mastery and reworked Burrwitch Outskirts. The hotfix was focused on fixing a major bug with the transfer stash, but also introduced many other fixes and changes.
Burrwitch Outskirts has been reworked to provide a more distinct environment shift from Wightmire, more of a change of enemies and more interesting and varied flow.
Probability to Hit System: Fixed legacy bug that was causing critical hits and misses not to be calculated properly, created a new equation to provide better scaling at higher levels, rebalanced player and enemy offensive and defensive ability.
Adjusted enemy skills to try to smooth some of the damage spikes people have been experiencing.
Standard skill throw speed increased 10%.
Physical and pierce damage bonuses from cunning slightly increased.
Soldier: Blade Arc cooldown removed, mana cost reduced and damaged reduced accordingly in order to differentiate it from Blitz. Blade Arc will now provide more spammable AoE damage that is efficient against crowds but not as much against single opponents.
Soldier: Blitz damage reduced and cooldown slightly increased. This should reorient it a little more toward crowd control and mobility rather than straight up AoE damage.
Soldier: Field Command converted from duration to toggled buff. Bonuses changed from protection and attack speed to %protection, %OA and %DA.
Soldier: Added %Physical Damage bonus to Fighting Form.
Soldier: Increased %Weapon Damage on Forcewave (also fixed bug that was causing %Weapon damage not to work on this skill type).
Soldier: Changed Will to Live to use new %Healing plus an absolute heal value and removed regen over time.
Soldier: Internal Trauma skill now actually causes internal trauma damage.
Soldier: Adjusted Overguard to give a big boost to shield recovery and then had the block chance scale over time. The more frequent chance to block should make the skill a little more effective at lower levels.
Adjusted Pet control modes (Aggressive, Defensive, Normal). Defensive mode now greatly favors attacking enemies that are attacking the player.
Dramatically increased the probability of Focus items generating a % dmg suffix, over other stats.
Rare Affix balance pass to selectively raise / add bonuses to some of the more underwhelming rares. This wasn't a comprehensive effort, we've been going through them as they come to our attention, so there may be more to come in the future.
Epic item balance pass.
Adjusted the level drop range of epic items and the level requirements of epics in the 1-25 range. Epics now start at a minimum level requirement of 14, stats adjusted to match. You may encounter some new epics within the Alpha that you cannot equip yet.
Slightly increased the % dmg values on low level armor and accessories.
Increased % pierce dmg on gear.
Rings, Amulets and Medals now have base stats. The different varieties of accessories provide different base bonuses.
Rings, Amulets and Medals can now drop as white quality.
The Warden's door now re-opens when he is defeated.
Removed level requirement from common armor and adjusted physique requirements to compensate. Often by the time players met the level requirement, they had already exceeded the physique requirement, such that characters with higher physique were not gaining as much benefit from their investment by being able to equip higher protection armor early then other builds since they were gated by level.
