Psychic Safety Math-hammer

Decided to run some math to see just how effective my Gloom Prisms are, and I figured I would share it here for anyone to use.  These chances I am listing are for both the power successfully casting (at various leadership values) and getting through different forms of Deny the Witch and such.


Def/LD ............... 6 ........... 7 ........... 8 .............. 9 ............ 10
Basic Deny.......... N/A ..... 48.61% .. 60.19% .. 69.44% .. 76.39%
Psyker ................. 27.78%.. 38.89% .. 48.15% .. 55.56% .. 61.11%
Psyker++ ............ 20.83%... 29.17% .. 36.11% .. 41.67% .. 45.83%
Tau Amulet ......... N/A ..... 19.44% .. 24.07% .. 27.78% .. 30.56%
Gloom Prisim ....  N/A ..... 24.31% .. 30.09% .. 34.72% .. 38.19%
Kharn .................... N/A ..... 9.72% .... 12.04% .. 13.89% .. 15.28%

Bleh, took me longer to figure out how to format this in a readable manner than it did to crunch the math. While the Gloom Prism isn't quite up there with the Tau Amulet, it certainly makes any of my squads hugging a Spyder feel safer.

Ahhh, you left out fortune that allows you to reroll deny the witch lol.  

Can't say I'm overly familiar with that one. Is that a psychic buff, or the single use one Eldar get?

its the spell that allows you re-roll saves.

It also lets you re-roll Deny (with probably a higher lvl psyker as well)
