Adopting Psychic Powers from Other games

By coolzyg, in Black Crusade

Hey all,

I'm working right now adopting psy powers from other games for BC. I found here some rules for the start:

Those are adopted powers from DH to RT. I think that it's not completed so I throw out overbleed (because it was reason the powers were overpowered) and gave Focus power modificators from -40 to +40 depending on threshold. Also where text spoke of WP Bonus I used Psy Rating. I assumed that threshold 15 is +0 and +5/-5 to threshold give +10/-10 Wp test for focus. I would give what i've done but, I'm writing in polish for my group so it won't be helpful for you.

But I have problem with rules for Powers from RT and DW. Although those powers also are used by WP test just like in BC. In DW/RT all tests are Wp+0, unlikely to BC where powers have + or - modificator to focus test. So I wanted to ask how can I adopt those powers to BC? It's stupid that Librarian can use every power by just passing Wp and Evil Librarian have sometimes harder time because of negative modificator.

Cheers

Keep in mind that many of the powers with penalties attached are typically more powerful than their DW/RT equivalents. Winds of Chaos shows this pretty well.

In fact, Vortex of Doom is really the only power that comes close to BC level insanity. There are some others which do well, but this is by poorly crafted rules, rather than written power. (Compel gets a little crazy)

So while there are some penalties in BC, which would you rather use? Smite or Ygethmore's wrath?
