Statblocks are no longer restricted to basic DND 5e fields and layout with the introduction of custom statblocks!
Custom statblocks use markdown to create the layout so you have the freedom to adjust the fields and layout to suit your game system and personal preference, all in the same way you write object notes. You can also use markdown templates and snippets to help you build up your statblocks quickly.
Any existing 5e statblocks can be converted to custom ones at the click of a button and there is some new markdown syntax to allow numbers in custom statblocks to be clickable to change their value easily.
For more information and some custom statblock examples, see Using Statblocks.
