Fixed a bug where the bonuses from stats that grant extra effects to "you and allies affected by your auras" would not correctly apply in some cases, such as when transitioning areas.
Fixed the most common client crash that could occur when entering a Delve or loading the Delve Map, as well as various other issues with the Crawler's behaviour and selectability in Delve.
Fixed a client crash that could occur when fighting The Animal Pack.
Fixed a bug preventing players from being placed on the Delve Ladder.
3.4.0d Patch Notes
Monsters in Delve now use EMP attacks less often. The EMPs also take longer to cast and last for half as long.
Fixed a graphical crash (which often happened with Izaro)
Fixed a bug where the attack speed bonus on Speaker's Wreath was calculated incorrectly.
