Miss on a thunderstone

[Helaman]

In a PbP game of Master of the Fallen Fortress for PFS play at the Moment and one of the team has tossed a thunderstone at the feet of a target... AC is 5 for that. And they rolled a 4.

Normally, for Alchem Fire or acid, I'd apply the splash damage rules and table, however the thunterstone has no rule for splash.

Do I rule it a hopeless miss with no ill effect for the target, rule that it didn't detonate or use the splash table and apply the affect. Given it affects all creatures in 10ft there seems to be no penalty for missing if thats the case.

Welcome any clarity you can give.

It is a thrown weapon with a range increment of 10.

If you miss, then you roll for the scatter rules as to where it lands.

1d8, with 1 being towards the thrower.

For every range increment it was thrown, it scatters that many 5' squares along the trajectory rolled by the d8.

Then it would do its sonic boom thing and affect everyone within 10' of it I believe.

I would handle it like a miss with a splash weapon. It still landed on a hard surface SOMEwhere and went boom.

Each creature within a 10-foot-radius spread must make a DC 15 Fortitude save or be deafened for 1 hour. A deafened creature, in addition to the obvious effects, takes a –4 penalty on initiative and has a 20% chance to miscast and lose any spell with a verbal component that it tries to cast.

Since you don't need to hit a specific target, you can simply aim at a particular 5-foot square. Treat the target square as AC 5.

If you miss the target (whether aiming at a creature or a grid intersection), roll 1d8. This determines the misdirection of the throw, with 1 falling short (off-target in a straight line toward the thrower), and 2 through 8 rotating around the target creature or grid intersection in a clockwise direction. Then, count a number of squares in the indicated direction equal to the range increment of the throw. After you determine where the weapon landed, it deals splash damage to all creatures in that square and in all adjacent squares.

Range increment on the stone is what... 20 feet?

[Helaman]

20ft according to the PRD. so its the 2nd range increment, being 40ft from the thrower... which would throw it off the side of the tower maybe? Will have to check the module.

The weapon scatters if you miss :

345
3X7
218

with X being the target (range increment) x 5', then it detonates per the thunderstone

You can throw this stone as a ranged attack with a range increment of 20 feet. When it strikes a hard surface (or is struck hard), it creates a deafening bang that is treated as a sonic attack. Each creature within a 10-foot-radius spread must make a DC 15 Fortitude save or be deafened for 1 hour. A deafened creature, in addition to the obvious effects, takes a –4 penalty on initiative and has a 20% chance to miscast and lose any spell with a verbal component that it tries to cast.

Since you don't need to hit a specific target, you can simply aim at a particular 5-foot square. Treat the target square as AC 5.

SO: if you throw 0-20', and roll a 1, it would land 5' short, towards the thrower.

If you throw 21-40' and roll a 1, it lands 10' closer to the thrower, and so on.

If there is an intervening hard surface, such as an over-throw in to a wall, the stone would stop there.

There is a rules question dealing with bomb scatter here:

Thx all

Bad me!
