Because I’m bored at work, I thought I might do a stat guide for the OP?
: Occasionally obtained from defeating enemies, that number to the left of your health/stamina bar. Used to return to human form (to summon others), kindle bonfires (5 more estus flasks), increases item drop rates (cap at 20), increases “Chaos” damage (cap at 10), used for raising allegiance with some covenants.
: Increases stamina and maximum equip burden. Stamina is used for attacking, blocking, sprinting and rolling – basically everything. Equip burden determines what gear you can use and how mobile you are. Under 25% of your max burden and you can roll freely. Under 50% and your movement speed and roll are slower, but workable. Under 100% and you’re much slower and roll heavily with a long animation to get up. Over 100% and you plod ridiculously slowly and can’t roll at all.
40: The stamina cap, and therefore the only number worth mentioning.
: Determines how many spell slots you have for all sorceries, miracles and pyromancies.
10/12/14/16/19/23/28/34/41/50: 1-10 spell slots. (6 or 7 is probably enough for anyone.)
: Your health
30-50: Enough to let you take a few hits in PvP and NG+.
The following stats suffer greatly from diminishing returns past 40, but I’ll jot down any reason to go past it for completion’s sake.
: Determines whether or not you can swing a weapon or use a shield effectively, as well as increasing damage with weapons that scale with it.
16: Claymore, Zweihander (two handed), Eagle Shield, Black Knight Shield. The go-to value for non-strength builds.
27: Optimal benefit for using weapons two-handed, lets you use anything that might benefit from both strength and dexterity (28 for the Murakumo one handed).
40: Optimal benefit for using strength weapons in one hand, can one hand anything worthwhile and two hand everything else.
(51/58/66): Every shield/one hand every weapon/max possible damage two handing (For the love of God, don’t go this high >.>).
: Increases damage for weapons that scale with it, slightly increases casting speed.
18: Lets you use all Black Knight weapons and crossbows.
24: Covers every weapon that has a dexterity requirement to wield at all.
40: Optimal benefit from dexterity weapons.
(45): Max casting speed (not worth it).
: Requirement for sorceries, increases damage for sorceries and weapons that scale with it (Magic/Enchanted).
10: Let’s you buy spells from the vendor at Firelink and Logan at the Archives, can use some basic utility spells.
12/16: Lets you use the best Catalyst for non casters/ more advanced utility spells (Resist Curse/Poison, Cast Light, Great Magic Weapon/Shield).
25/32: Crystal Magic Weapon/Tin Crystallisation Catalyst and 5 orbs with the Soul mass spells.
44: Crystal Soul Spear sorcery.
(50): White Dragon Breath sorcery (not really worth it).
: Increases magic defence, requirement for miracles, increases damage for miracles and weapons that scale with it (Blessed/Occult).
18: Emit Force and Homeward utility miracles.
28/30: Wrath of God miracle/Darkmoon and Sunlight Blade weapon buffs.
40: Optimal benefit from faith scaling.
(50): Sunlight Spear (nifty knockback, but takes up two slots with just 5 uses. Not really worth it).
: Joke stat, disregard. (Increases poison resistance, and increases defence slightly faster than other stats).
: The most important stat on your armour. Higher poise means that you won’t get staggered when you’re hit by heavier attacks, which is particularly useful in PvP.
40: One hit from most one-handed weapons.
55: One hit from larger weapons (notably the Claymore and its ilk).
76: One hit from very large weapons, eg. Black Knight Greataxe and Zweihander.
