4.3 is fairing well in the world of certification, so I thought I might give everyone a preview of what it has to offer.
Aside from some much requested bug fixes, 4.3 will offer a new feature, "Bolster", and some significant changes to the Exclusive Raid system.
Bolster
Imps can now "Bolster" any Room, with the exception of the Guild Lair, to provide unique bonuses that further enhance those Rooms. The strength of the bonus is dependent on the number of Imps you assign to a Room, so you can either double down on a single Room or spread them throughout your Dungeon for a wider variety of lesser bonuses-- the choice is yours.
Assigning an Imp to Bolster a Room will instantly apply the Bolster bonus, but also occupy that Imp until you assign him to another project. Each assignment will cost an amount of Gold dependent on the level of the Room to which he is assigned.
Exclusive Raid Changes
A number of changes will be occurring to the Exclusive Raids. They will now be hosted bi-weekly and will award Dreadstone. Gem rewards will be changed to account for this, and you should also be forewarned that they will be significantly more difficult. Each Exclusive Raid is now themed to provide a more engaging experience.
More details to follow next week!
个人翻译版本如下：
除了修复一些迫切要求的bug，4.3版本将提供一些新的功能：1.“强化” ，2.有重大改变的限时袭击系统。
1.强化
小鬼现在可以“强化”任何一个房间（除了公会巢穴外），小鬼为玩家提供独特的奖励（就是指额外的buff）可以进一步强化这些房间。房间强化的程度取决于你安排到一个房间的小鬼数量，因此你可以安排两个小鬼在一个房间或者分散安排小鬼在你整个地下城中，你可以任意选折。
安排某一个小鬼去强化一个房间可以立即实现强化的buff奖励，但是这样做的话会占用一个小鬼直到你安排给小鬼其它的任务。安排小鬼强化将消耗一定数量的金币，这将取决于被分配房间的等级。
2.限时袭击的变化
若干变化将会出现在限时袭击中。新的限时袭击将会两周举办一次，并且奖励恐惧之石（紫石）。宝石（绿石）奖励将会相应的进行改变，但要预先警告大家新限时袭击将明显更加困难。每次限时袭击将会注入一个主题以便给玩家提供更好的用户体验体验。
更多细节请关注下周！
