Stats:

Perception: Perception is the most important stat for a Psi. This should be at or near 0% at all times.

Luck: This is the 2nd most important stat for Psi's. I have read countless posts where people with limited Psi experience try and explain how Luck is a meaningless stat, and you should basically ignore it.

Without getting to far into the math. 1% worth of Int is the same over time as 1% worth of Luck. While there is a Luck barrier, once you break that barrier, no matter what your level is, it rises very quickly, much quicker the int would.

Let's assume one point of Int = 1 Point of luck worth of Damage over Time.

In this scenario, it doesn't make a difference over time what you add your points to, or wear armor for. You get a slight bonus in PvP for Luck ( Burst damage ), and a slight bonus in PvE for Int ( No burst damage, less aggro jumps ).

Now add in Glancing blow's effect.

Given that most Psi's, have around 20% glancing blow, it's effectively reducing your damage over time, by 15% ( Negating the mandatory 5% Glancing blow ).

So Now that we know Ignoring luck reduces our damage over time by 15%, you are essentially getting 1.15x damage by taking Luck, instead of Int, which would only be 1x.

Not a huge bonus, but theres more.

Add in Psychotic Urges ( 30% Bonus Damage on crit's with PS and Choke )

Im gonna assume everything is Additive ( The lowest the game could make it, thus if it were Multiplicative, it would be substantially higher ).

While Int based Psi's also have the capability of benefiting from this skill, it's much less available. Essentially:

Int build = 1000 average damage, 5% crit, with Urges, will bring 2300 damage crits, 5% of the time. (Not including Glancing Blows). Which equates to an average of 1115 damage per hit, on average.

Luck build = 500 average damage ( probally wouldnt be that low ), 50% Crit ( could be higher with Legendary's ), Urges, will bring 1150 damage crits. Which will equate to an average of 1650 damage, per hit, on average.

Oh, but there's more.

Fear of Failure is a 9% bonus. On a crit, its 9% of your crit value. Using the same math presented above.

1115 on average with a 9% boost will be 1215.35 A bonus of about 101 damage.

1650 damage, per hit, on average, with a 9% boost is 1798.5. A bonus of about 149 damage.


Based purely on the math, All Psi's should only take intelligence when it's value on an item is 1.5x that of a same level item, with luck on it, or if Intelligence is a 2nd stat on a item, and comes free.

But by spending some time on allodsdatabase looking at purples, and oranges, There is no logical reason why a person would take int over Luck. This is not to say that you shouldn't keep Intelligence in a reasonable range, as at a certain level of crit %, Intelligence adds more Damage per point then more Luck does, but that's my little secret :).
