Otherworldly Patron: The Ancient Dragon [Third Draft]

Always wanted to update this one. Got into a conversation the other day that got me thinking about it, and it just kind of went from there.

One thing I didn't like about the v0.2 of this patron option was that it tried too hard to be dragon-agnostic, creating a spell list that attempted to address every type of dragon possible. What it generated was something of a bland mess that had a lot of holes and no central feel.

So, I made six spell lists instead, one for each damage type of dragon (almost; acid and poison have to share).

It was a huge pain in the butt. I hated it from a simplicity-in-design standpoint. But it was the right call, I think, to preserve the feeling of this patron.

But, of course, that's not the only thing that got changed. Changelog!

CHANGELOG:

• Diversified and reformed the spell list(s), trying to keep a central idea of dragon-ness while showing deviation across the various dragon-types.
• Moved Ancient's Breath (now Breath of the Ancients) to 1st level, and included a note saying that yes, dragonborn can and will have two different flavors of breath.
• Added Dragonscales at level 6, a shield type ability that does what I was trying to make shield do, without costing a spell slot. 
• Reworked Blood of Dragons making it less dependent on coming into contact with a specific type of damage. 
• Minor reworks to Draconic Apotheosis, to make it function with the new Blood of Dragons and Breath of the Ancients.
• Added Invocations, including the much-loved dragon chest, small buffs to the Pact of the Chain pseudodragon, a Pact of the Blade weapon, and more!

CONCERNS:

• I'm not sure of the damage ramp on Breath of the Ancients, could use another look. 
• Blood of Dragons may be too good, and also, is it clear? Could also use a look.
• The pseudodragon invocation (Dragonling) may have unintended consequences, maybe?
• Giving heavy armor to warlocks is probably an okay call, given that this invocation matches numbers with Armor of Shadows pretty well, but I'd still like to have Knight of the Beyond be looked at. 

WHAT I LEARNED:

• Usually, it's worth doing the big, stupid, extra-work-pain-in-the-ass thing to preserve flavor.
