Well, at a first glance the new attributes allow for much stronger characters now.
Health:
If you max out health you end up a bit short of 800 hp. Depending on the perks you take you get an auto heal at half of the attribute and constant healing in form of glutton for pain at the end. So high health with constant healing aside of any potions you might apply yourself. I liked that very much.
What i liked less was its corrupted iteration. 5 points corruption to get that sweet scaling from corrupted if you would put corruption into it. The problem is then, although it conveys a number of nice resistances, it disables the auto heal. And you need that in combat with a halved health pool. Badly. It could see some use if maxed because it causes again a big reactive AOE procc if hit, the problem is that this is rather suicidal.
Grit:
Aside of that 5 point endurance boost which, i am sure, will form the basis of most builds it now adds directly to armor as dexterity once did. It also sports damage reduction at high point investment, namely Defensive Posture and Steel Thewed at flat 15% whilst attacking and that “can’t take more than 25% maxhitpointsin one hit” at the end. Considering the hefty health cost of corrupted attributes probably a staple for aspiring corruption sorceresses or sorcerers as is health. I could also see that working rather beastly not corrupted maxed out with maxed out health. High hitpoint with autoheal AND damage resistance AND the ability to use your weapons more? Where do i need to sign? This attribute can’t be corrupted.
Strenght:
I need to lash out here a bit as this works a bit differently now. There are strengh and agility based weapons and agility was… well bows for the most part until now. This is history. Its perhaps part of the reason why it underwhelmed me a bit but it introduces a bit much needed complexity. Melee weapons are divided up now between either scaling of strength (axes, swords, twohanded weapons, PIKES, etc) and agi (daggers, KATANA, SHORT SWORD, etc) If maxed AND corrupted to the max its really nice as it creates, aside of doing terrible damage with strength based weapons an additional corrupted small AOE that procs faily frequently… maybe 50 to 75% at the time making this a particualry nasty surprise with twohanded weapons such as longswords or twohanded axes. Potentially the best corrupted attribute, it limits your weapon selection, of course, and worse - health.
Authority:
This is a new one and i have to say not very noticable vanilla nor corrupted EXCEPT if maxed, which allows for TWO thralls and a horse and max corrupted, which will summon a demon to attack your foes at times. Thats all very nice and well, except that, as it has been pointed out before, a single thrall WITH increased attributes the “twins” lack can be comperable, so maybe the demon attacking is nice but it hardly justifies the sheer ammount of points being pured into as things are a bit more restrictive this time aroung and you need every point. Nice but in the end faaar too expensive and grindy.
Agility:
That is just a fantastic attribute. 5 points give you a 15% damage from backstabs. More on the table is general armor penetration and, THE SINGLE MOST IMPORTANT PVP ABILITY, Rolling Thrust. It takes a bit of practice and an agility weapon but when you pull it off you dont pay ANY endurance for your next heavy attack (only for the roll, which is great for mobility and thrusting attacks). With a shortsword, of all things, this feels like the old spear light armor builds. It works totally differently but the effect is pretty much the same. And boy does damage scale from this attribute. 120+ damage hits with a short sword? And PvP dancing with energy conservation? Who do i have to kill to use this? The attribute can’t be corrupted.
Then there is survival and expertise which convey nice bonuses to non-combat focused builds but basically cost too much points you can’t spare somewhere else for a combat build. Who cares for resources anyway?
All in all i think building a caster mandates going corruption, if for the spells alone, that being said it will not be match a uncorrupted combat character in melee in any shape or form. With most spells having more a utility function than combat applications (notable exceptions are the zombie mist and lightening storm), considerign the random nature and zombies not being a real threat that shifts favor squarely on noncorrupted iterations of health-grit-agility builds.
This closes my summary.
