Stats and How They Work

Note: All credit for the original thread goes to Daellia; I will simply be maintaining it subsequent to his departure. If you have any questions, though, don't hesitate to ask.

I've seen a lot of questions and false information about character stats thrown around on these boards, so I'm making this post to provide a resource for everyone for how exactly all of the stats work. Note that this guide is sorcerer-specific, I won't be covering Shadow benefits here (the only real differences, for those wondering, are that Willpower also affects their melee attacks, they need Accuracy rating, and for tanking, Defense, Shield, and Absorption).

First, some background. Nearly every stat in the game follows a diminishing returns curve. For those mathematically-oriented, these curves asymptotically approach a certain limiting value.

For those not so mathematically inclined, that basically means that the benefit you gain from adding a certain amount more of that stat gets smaller and smaller the more of it you have, with a certain "ceiling" it can never exceed. For example, crit rating limits to 30%. Thus the more and more crit rating you add to your character, the closer and closer you get to that 30% bonus, but you can never actually reach it.

Also, note that the benefit from each stat is on a separate DR curve, and raw percentage benefits (such as from abilities) have no effect on any DR curves (they are additive on top of them instead). Thus how much Willpower you have, for example, has no bearing on how much benefit you get from X crit rating, and vice versa. This doesn't imply that the DPS value of the stats are independent, but that's another discussion entirely.

Willpower vs Power

Increases force damage, healing, and critical effect chance. Each points provides 0.20 Force Bonus Damage and 0.14 Force Bonus Healing. Critical effect chance benefit scales slowly and limits to 30%.

Force Power
Increases force damage and healing at a slightly higher rate than Willpower. Each point provides 0.23 Force Bonus Damage and 0.17 Force Bonus Healing.

Identical to Force Power for Sages. Each point provides 0.23 Force Bonus Damage and 0.17 Force Bonus Healing. Also increases melee, ranged, and tech at the same rate.

Critical Rating
Increases critical effect chance with all damage and healing abilities. Benefit scales moderately and limits to 30%.

Surge Rating
Increases the bonus damage or healing from a critical effect. Additive with the base 50% critical multiplier. Benefit scales rapidly and limits to 30%.

Alacrity Rating
Reduces the cast time of casted and channeled abilities. Additionally reduces the length of the global cooldown for those abilities if their cast or channel time drops below 1.5 seconds. Does not reduce the GCD for instant abilities, nor for cast/channeled ones if their final cast time remains above 1.5 seconds. Additive with multiple Alacrity sources. New Cast Time = Original Cast Time * (1 - Alacrity%). Scales moderately and limits to 30%

Accuracy Rating*
Reduces chance to miss against a target, and once miss chance is 0%, begins to negate the target's Defense or Resistance. Boss targets are believed at this time to have zero innate force resistance, and force attacks have a base accuracy of 100% against all targets. Thus, this stat is worthless for Sages in PvE. In PvP, no gear stat gives resistance, and only limited abilities do. Thus it is generally worthless against most targets and not worth gearing for. Scales moderately and limits to 30%.

Shield Rating*
Increases your chances of "blocking" and attack with your shield generator. Referred to as Glance Rating on TORhead. Requires a shield generator in offhand, and thus is useless to Sages. Scales moderately quickly and limits to 50%.

Absorption Rating*
Increases the damage absorbed by a successful shield "block". Does not increase the damage absorbed by Static Barrier or similar absorption buffs/abilities. Requires a shield generator in offhand, and thus is useless to Sages. Scales rapidly and limits to 50%.

Defense Rating*
Increases your chance to avoid melee and ranged attacks. Dodge, parry, and a few other terms are all manifestations of this stat. Sage base defense is 10%. Has no effect on Force or Tech attacks. Generally useless to Sage. Scales moderately and limits to 30%.

Expertise Rating
PvP-only stat. Increases your damage and healing done to other players and decreases the damage you take from other players. Healing is increased by "ignoring" part of the Trauma buff that is automatically applied when you enter PvP combat, and thus scales somewhat better in actual effect than the percentage displayed on the character sheet. The damage bonus scale moderately and limits to 50%, while the trauma ignore scales slowly and limits to 30%.

The DR portion is now (as of 1.2) calculated directly off of the damage portion, and is equal to 1 - 1 / (1 + DamageBoost%). The net effect of this change to DR is that any character attacking another character with the same amount of expertise will deal the same amount of damage they would deal if both they and the target were at 0 expertise. Previously, the DR portion scaled somewhat better, so, for example, a 1000 Expertise character attacking another 1000 expertise character would deal noticeably less damage than if both characters were at 0 expertise.

*NOTE: Gear with these stats, while worthless to Sages directly, may be of some benefit if equipped to certain of your companions instead.

I've also made this handy graph showing the scaling of all of the stats. Left graph shows the total benefit of the stat based on how much you have, while the right graph shows the benefit of the next 10% of that stat based on how much you already have. Remember, separate stats have no effect on the benefits each grants, even if they give the same bonus (such as Crit and Willpower), and percentage benefits from skills and abilities are applied additively after the rating conversion is applied.

The first graph shows scaling from 0 to 1000 rating, the second from 0 to 2500. The third graph shows the percentage of the limiting cap obtained at each rating level. This is important, since the benefit rating gives you is proportional to how much of the cap you have remaining. ie. if you are at 60% of the cap, the rating will be providing you with 40% of the benefit it did when you had 0 of that rating). The fourth graph is simply a comparison of 1.1.5 to 1.2 values for Expertise.

0-1000 Rating Graph
0-2500 Rating Graph
Percentage of Cap Graph
1.1.5 to 1.2 Expertise Comparison Graph

Excellent, sticky requested as well.

By the way, there are still a lot of incidences of "Sorcerer" in there.

Good to see you taking over this.

BTW if you ever are looking for additional help, I should be around (either here or on the mmo-mechanics forums). I've just joined the development group at SimC so we should be able to keep that up to date with the sorc stuff as well.

This stats guide is very clear, accessible and helpful. Thank you very much.

Whoops, just realized that the bottom still references "", which was converted to months ago. I updated the link, but forgot to update the paragraph above it.

erm i have some qus to ask... how do u know all the stats limit are at 30% i think its very hard to balance out for all... and the limits are without buffs? and in my point of view for crit chance, i did make it to 29.98% which is the best i can do, i felt that it crit alot lesser then when i was as 31-32% without buffs, meaning with 29.98% + 5% buff which is 34.98% is really lesser then 31-32% + 5% which is 36-37%... are the limits a diminishing returns or they r just a cap which adds alot lesser when it hits that cap? im very doubtful about this atm... hope someone can explain to me

Bear in mind it's talking about the contribution from different stats, not the final figures you see on your character sheet.

When we say Critical Rating is limited to 30%, that's 30% plus the 5% base, plus spec/companion bonuses, plus buffs, plus the crit from Willpower (which also caps at 30%). 30% total crit chance is nowhere near 30% from Critical Rating. Hovering over crit chance ingame will show you the individual contributions.

At any rate, you won't get anywhere near 30% from Critical Rating in practice; there simply isn't enough available from gearing even if you wanted to. Furthermore, it is a true, asymptotic curve; you'll get closer and closer to 30%, but you can never reach it.
