One of the new rules we are introducing, more so for 5E than Skillskape (It already exists in Chivalry and Sorcery), is the notion of hindrances for characters, such as Cowardice, Pride etc.

For 5E we shall be utilising Traits, Flaws etc that currently are there only for flavour.  Characters may learn to identify these hindrances and work to remove them.  In doing so they grow their potential for achieving Grace. 

As a Paladin grows in Grace they unlock their Powers, until such point as they are full of Grace and are Truly a Paladin of Power.

In the Deeds of Paksanarrion, Paks slowly gained powers unwittingly throughout the books.  In game terms she showed she gained Grace without knowledge and was able to sense Evil and cure wounds before she even considered training as a Paladin.

These updated rules will more faithfully recreate the Paladins from the novels.
