Night Spinner Stats (verified)

[Herald of Nurgle]

I'd force a re-roll, or simply bunch them up. Moving through dangerous + Night Spinner 1 is a 2 or less, and so on.

There is only one dangerous terrain, much like every other place terrain is talked about in the main rule book.

The markers removal depend on the exact wording of the rule.

Additional notes.

1. This template has a 55% chance to hit before I calculate the deviation numbers that will land on top of a tank. (From previous numbers it should rise to 85% ti hit the tank with the center of the blast)

2. This tank has a 16% chance to immobilize a land raider. For comparison a twin linked lascannon only has a 10% chance to stop (immobilize/wrecked/destroy) Armor 14.

This tank has a 16% chance to immobilize a land raider.

True only if there is a hit in the first place. People should also not place too much dependence any single shot. Any time one's strategy is dependent on a single die roll with only a 1 in 6 chance of success one is likely to be disappointed in the result. It's certainly useful in that role, especially when adding it as an additional chance at stopping that AV14 menace along with other shots taken, but I wouldn't stake the outcome of the game on the one shot or any single shot.

Give up a Fire Prism, which can kill a Land Raider, for a 1 in 6 chance of Immobilizing it? No thank you. Seriously people, chill out, it's an over-costed, under-gunned tanks that competes against some of the best Heavies in the game.

If it had a second mode of fire or was a Fast Attack choice, then it would be worth a look, but as it is... not for me.

Mathhammer-wise, what are the odds of a Fire Prism blowing up (or destroying or immobilising) a Land Raider? Hint: really low. The odds of immobilising it with the Nightspinner are higher.

"The unit counts as being in difficult and dangerous terrain" is how they word it, I believe. So multiple templates don't stack.

Some quick math, I don't know of any flaws.

Night Spinner
To hit a shot center of mass of a Land Raider.
Assumptions:
BS 4 , Can See Target, True Dice

N[((2/6)+(6/36)+(4/36)(170/360)) + (1-((2/6)+(6/36)+(4/36)(170/360)))*((2/6)+(6/36)+(4/36)(170/360))]
80% chance for center of template on the vehicle.

To immobilise or wreck the landrider.
N[.80 (1/6) (2/6) (2/6)]
1.5%

To immobalize via dangerous terrain.
90% chance for the template to hit the vehicle.
15% to immobilised

Total 16.5% to immobilised

Only a single flaw that I see in the math: According to everything I have seen the Night Spinner is BS 3...

...slightly higher, but also really low.
