Wow, do you mind me asking how you guys have most of the ability tree done? The Wiki says there are 627 slots and it seems even the highest level players are in the high 300s. Obviously Training helps, but that would only account for ~400 AP. Unless you mean most/all of the AP they need, ie. elemental or dark/light spells for melee, etc.
There is a few people that actually have filled the entire ability tree, but those are usually old players, who apart from being high level also have been around for a long time and been getting a lot of artifacts.
You can also buy artifacts, just like you can buy hath. And as a long time-player and if you've been putting up good galleries and running H@H, they've earned up quite a bit of cash.
There is a cut-off after all, after lvl 250 you don't get any more ability tiers.
But for us mortals, there is no real need to fill out the entire ability tree. If you are a melee, you don't really need the offensive spells, and if you are a mage, you don't really need the OC tanks.
OC tanks are 180 AP to fill out, all offensive spells 108 AP and another 90 AP for the resistances.

Given that most of the Legendaries, Gods and Trio do dark or soul damage with their Spirit Attack, is it worth investing AP into Soul & Darkness resistance abilities? That is, after maxing out HP/MP/SP/OC Tanks first (I'm fine with no EXP boosts for now). I assumed that having 20% more mitigation would prove to be significant against their Spirit Attacks and thus hopefully cut it down to the point where it won't take the max amount of SP when Spirit Shield is activated, but I figured I'd ask here for further opinions.
You don't get 20% mitigation, it doesn't stack like that.
10% +10% gives you 19% mitigation, and the more mitigation you have from different sources, the less you get.
Every little bit helps of course, and if you have the AP for it then you should use it.
But XP tanks does a lot, which helps with quicker leveling, which means more AP to use. Snowball effect.
But you are indeed right that increasing the specific mitigations does help. For example, when fighting FSM it's a good move to bring a set of armor with "of the spirit-ward" suffix (dark mitigation).

Did the drop rates for artifacts use to be higher? Or maybe the rate of getting AP from artifacts was.
That would require some 200 artifacts while getting AP for each one. I've never gotten AP from an artifact (only crystals and stat bonuses I believe).
Also, while I'm here, do you guys know any good ways to grind proficiencies? I've searched the forums a couple of times and not found anything. Would it just be better to do Grindfests on Easy so I can reach higher levels and thus attack/defend/heal more? On average my proficiencies are about half of my level now, though I've seen it recommended to keep them at 75%
Crystals are a fairly new thing, so before them, artifacts of course had higher chances to give the other rewards.
And since there is a max on how many bonus stat points you can get from artifacts, after that peaks out you'll also get more of the other rewards.
Artifacts can give AP, bonus stat points, hath, crystals or energy drink.
I seem to be getting lots of energy drinks (replenishes 20 stamina).
As for grinding proficiencies, it depends on what type of proficiency you wanna grind.
Weapon proficiencies are given when you attack with that weapon, or with magic missile for staff.
Armor proficiencies are given when you are attacked.
Spell proficiencies are given when you use spells of that type.
So for weapons and armor, hit things and get hit, simple as that, crysfest on easy is pretty good, crysfest costs less stamina and on both crysfest and grindfest monsters only do 50% damage on the first round, then the damage increases with 1% per round (meaning per new round of monsters, not per turn), and they quickly grow in numbers so after a few rounds you'll start maxing out with 9 monsters per round, meaning lots of incoming hits, but they don't do all that much damage.
For spells, find the cheapest spells of the proficiency you want and then spam it.
Cure for curative, weaken for deprecating, elemental spikes for supportive etc.
Training assimilator increases the chance of gaining proficiency.
Also, proficiencies will catch up to you. As you get higher, it requires more to get to the next level, meaning you have more time to earn proficiency before you hit the next level.
