From Software and Bandai Namco have announced a pretty big patch for Dark Souls III, and it's scheduled to land on Wednesday of next week. It's mainly focused on PvP, but there is other stuff in there as well. Below is the full list of changes:
• Fixed issue where a player could invade another player during a boss battle.
• Fixed issue where an enchantment could be applied to weapons which normally could not be enchanted.
• Fixed issue where, when items are used while casting magic, display glitches could occasionally occur.
• Fixed issue where it was possible to cancel immediately into a second magic spell after casting the first one.
• Fixed issue where the first part of a skill action could be skipped.
• Fixed issue where a single item could be used indefinitely.
