I had developed a 'Heavenly Warrior' style in Rpol game which uses all four virtues and willpower as actual requirements learning the charms in the tree. Compassion line specifically has nice defend other charm (allows perform defend other as reflexive action and it allows add compassion dots onto parry DV and even if foe surpass your parry DV the foe cannot strike the one you protect and instead is forced to hit you).<br/><br/>Another central part is growing connection with one's own weapon by communing with weapon's god and all artifact weapons have god inside them. A kind how shinigamis from Bleach form connection with their weapons and open new amazing powers as their connection and communion deepens.<br/><br/>It does not use shields per say, but it works with any weapon so shield could be said weapon. It was not fully completed though and was kind unfinished.<br/><br/>However, DB's have native charms which achieve you want them to; Virtuous Defense allows DB to jump to parry attacks which target folks in essence x yards from them and if they parry they can use blinding spark parry to either blind enemy or distract them to give -2 penalty to actions until their next tick. It would not be far fetch to add charm which causes further harm on foe when you successfully parry the attack (and DB's can learn semi-perfect parry charm).
