Does anyone have any experience with this power in game?
it seems to me, that is the equivalent of 'death spell' for a low low cost of 13 PT.
if you win a Willpower test opposed by opponents strength, you knock them to the ground , PLUS deal 1 level of fatigue per success.
Overbleed, for every 5 pts you exceed the threashold, you get +10 to your WP test and 10m extra range.
I'm guessing most players and npc dont have more than 4TB , and most have a 3 in toughness, not to mention that most npc (daemons and orcs aside) dont have a signifigant strength score , 3 on average 4 on the upper end.
So this spell seems like a wrecking ball of a power, perhaps even more so than force bolt potentially, even without augmentation, because the psyker gets to test his BEST attribute against most other players WORST attribute.
Some easy numbers to consider:
if you had a +10 bonus to your power roll, (via 5-7WP bonus, 2-3 power well bonus, and +2 discipline focus) and a Psi 5
you are assured of success in casting the spell, and have a 78% chance to cast a spell with a 90+% chance of success on your willpower check. depending if your WP is only 5 (90% chance of success), or 100% chance on our willpower check if you have discipline mastery
Here is a program I made to calculate success on casting, showing the dice combinations with failures:

you can fiddle with the numbers however you want, but it seems to me this program is a wrecking ball even for Adepts, who only get Psi 3, and none of the power well bonus or Dispipline bonus, and pack a measly willpower bonus of 5
