The Book of Syncletica is continually updated with news and changes to the class. Currently the guide has information relevant to Update 23 with revisions for changes from Update 25 added as time permits.
Update 19 dramatically revised the enhancements format, which not only added a new prestige tree but completely changed several essential characteristics of the Monk class in Dungeons & Dragons Online.
If you haven't played DDO since July 2013, be sure to use this guide to acquaint yourself to changes in the Monk class as well as many others.
