D&D 5E Quintis the Warlord, what can he do and when can he do it?

[Tony Vargas]

So, lots of great ideas have come out in the past few weeks. I am not so good at the mechanics but I think two ideas that are very interesting are a spell commander type warlord and a social / diplomat type warlord. Anyone have any ideas how this would work rule wise?

I'd thought of the idea of a Mage-Commander as a leader of casters, who might be only a 'theoretical thaumaturgist,' himself (thus he might act as a forward observer, or grant spellcasting actions, or something), or who might actually cast (maybe spells that enhance or meta-magic other spells?). I suppose another take would be a 1/3rd caster like the EK who leverages spells to further bolster his allies whether they cast or not.

The SWSE Noble would be a fair guide to the social/diplomat type from the little I've seen of it.
