The October 7 patch changes the way certain skills work, fixes class errors, and reduces the minimum step for automatic price reduction on Bazaar from 500 to 1 gold.
Lightning Blast now favors normal targets over destructible objects as long as the number of chain hits does not exceed the number of such targets. Fixed some situations with movement near Lagon's tentacles. For your character, check exactly the affected tree nodes: these are spot changes, and not a replacement of all assembly rules. The notes also list changes to the Nexus interface and notifications.
