To prepare for The Ringed City DLC, Dark Souls 3 is receiving a major patch that aims to bring bug fixing and balancing. The patch will go live March 24. The DLC releases March 28.
The game will receive a boost in framerate for PS4 Pro owners to take advantage of the increased power of the console. The update looks like it will make “great” weapons more viable as it will decrease stamina depletion when attacking with ultra greatswords, great hammers and greataxes. Two new maps will be added to Undead Match, Dragon Ruins and Grand Roof. The damage dealt with poison and toxic is increased but the duration of it is shortened.
