I'm trying to compile all the psyker balance rules into an easy to read thread, so for people who have games where the psyker is out of control powerful, or maybe the rules as is just dont seem right have some options....
Obviously there are some power nerf spells, and I guess we can spell them out here too, but I was hoping for more like rules fixes.
I think the most popular one I've seen so far, and happen to like myself is :
Replace all instances of will power in a power description with 'Psi rating used'
-It is important that ALL aspects of a power that are tied to will power are changed over to Psi rating, otherwise, a psyker fetter casting (lets say psi rating 2 or 3, will power 7) dominate, still beats the psyker push casting dominate with a psi rating 9. Obviously damage, range , etc also apply here for the same reasons.
-Also, most combat skills require 2 stats, whereas the psyker really only has 1 stat.... Successful Ballistics tests gets its damage determined by the weapon being used. Melee tests get a weapon damage MODIFIED by your strength score. psyker with high WP, neither has to make ballistics tests or melee tests to hit, he uses his WP, he further doesnt have to care about his strength score, as he relies on his will (force bolt, the biggest offender), and he doesnt really need his psi rating, as a psi-3 with 7wp/power well can manifest force barrage 95% of the time or better.
We could say that psyker powers are not all combat orientated. and true some minor powers are not, as are some majors... but for the most part, its all about killing people.
Limit or remove overbleed altogether from fettered casting.
-To use a dnd 3.5 analogy, how can you fight defensively and power attack for full!?
Minor Powers dont invoke perils of the warp
-This isnt really as much of a problem with fettered casting for pcs... however I posit that if you had even 1 latent psyker on every planet, and only 1 was born once per decade, and they all only cast their power once before realizing they should wait for the black ships to come and take them to the empra to be eaten at snack time... that the Imperium as a whole would be a big empty place, full of Unbound daemon hosts. Yea, latent psykers get major powers, but we can just pretend they dont destroy whatever planet they are on, unless there are PC's walking around.
Alternatively, I all freshly made Sanctioned Psi rating 1 psykers being produced would also destroy the Imperium, merely on the basis that they could not fetter their power. So therefore, I reccomend.Minor powers shouldnt be able to manifest perils... leave it at warp phenomena.
Statistic capping for games with those Willpower 7+ psykers?
-Not as hard as you think, getting 37+ on a starting roll, getting either sanctioning bonus or tarot reading, void born, and the mind cleansed package, will get you a starting WP of 50+... +20 for stat ups, now your in the 70s, taking ascension gets you another +10 in statups, and potentially another +10 in starting packages for ascension getting you to 90+ without having unnatural will power... ewwww...
How hard is it you say to get a 37+ or a 40 starting characteristic? Not terribly hard... that is, given that you get 9 rolls, and 1 reroll giving you 10 shots at a 40, which is slightly less than 10%. [insert formula here]. Given that for all rolls of 37-39 in WP get 2 more chances to become 40+, and any stats from 34-36 get a chance to collect both the tarot reading and sanctioning will bonuses, its a close shot to 10%.
I would further posit, that unless you are choosing your career path BEFORE you roll stats, that your characters probably arent making sub par psykers (and nor would the empra accept them anyway), so therefore Im guessing only the character with the wicked will save in the group is taking it. so that gives you for shots at a 10% psyker... Ofcourse, you can always try the tried and true, 'accidentally die so I can make a new character maneuver' ...
if you are using Rogue trader, then your STARTING STATS are 25. even easier to get 40+... then again WP isnt quite as good in Rogue trader...
In short: Not that hard!
What would be a good stat cap for PCs, if there was one?
Re-write the Powers that can be over abused
- I dont like this one, it requires a lot of work, and furthermore, I think most of the spells in the game are fine, until they are abused by a high will power psyker.
