Creating custom magic item: Teleporting Tea Ball

I am playing a silly little old lady Druid in my upcoming campaign (D&D 3.5). I want her to specialize in poisons. My DM has let me create a list of minor poisons herbs that I can use.

What I want is to create a teleporting tea ball. This will on command teleport into the stomach of my attacker with the poisonous herb. This then poisons the foe. Then with use of command word the tea ball is teleported back to my character (continuous use). Not the most effective way to damage a foe but I thought it would be funny.

If I’m doing my calculations right to make this wondrous item it would cost 88,200 gp.

(teleport object 7th lvl spell x caster lvl 7 x 1800)

Does this seem a fair price?

Do the ball lightning and spark shower functions of a Ring of Shooting Stars allow saving throws?

In the SRD it states:

The first special function, ball lightning, releases one to four balls of lightning (ring wearer’s choice). These glowing globes resemble dancing lights, and the ring wearer controls them in the same fashion (see the dancing lights spell description). The spheres have a 120-foot range and a duration of 4 rounds. They can be moved at 120 feet per round. Each sphere is about 3 feet in diameter, and any creature who comes within 5 feet of one causes its charge to dissipate, taking electricity damage in the process according to the number of balls created.

It also states:

The spark shower is a flying cloud of sizzling purple sparks that fan out from the ring for a distance of 20 feet in an arc 10 feet wide. Creatures within this area take 2d8 points of damage each if not wearing metal armor or carrying a metal weapon. Those wearing metal armor and/or carrying a metal weapon take 4d8 points of damage.

Neither of these functions directly address a need to either make a saving throw or the requirement to make a ranged attack to hit a target. Should these functions require either saving throws or attack rolls?

Assigning Balls to Bins with Constraints on Which Ball to Go to Which Bin?

Let us say we have $ m$ bins and $ n$ balls. Every bin $ i$ has capacity $ c_i$ which is the number of balls that can be put into bin $ i$ . We have $ c_i\geq1$ for all $ i$ . For each bin $ i$ , there is a collection of sets $ S_i=\{X_1,X_2,\ldots,X_{k_i}\}$ for given $ k_i$ . Each $ X_j\in S_i$ is the set of balls that can be put into bin $ i$ . We have $ |X_j|\leq c_i$ and $ \emptyset\in S_i$ for all $ i$ .

For example, for $ m=2$ and $ n=3$ , with $ c_1=1$ and $ c_2=2$ , say we have $ k_1=4$ and $ k_2=5$ . Say we have $ S_1=\{\emptyset,\{1\},\{2\},\{3\}\}$ . $ S_2=\{\emptyset,\{1\},\{2\},\{3\},\{2,3\}\}$ . This means that ball $ 1$ , $ 2$ or $ 3$ can be each assigned to bin $ 1$ . Also, each ball can be assigned to bin $ 2$ . Further, balls $ 2$ and $ 3$ can be together assigned to bin $ 2$ . We might have an instance with $ k_2=6$ and $ S_2=\{\emptyset,\{1\},\{2\},\{3\},\{2,3\},\{1,2\}\}$ for example.

We want to assign the maximum number of balls into the bins. Is this easy or hard?

Idea behind using binary search to solve rolling ball?

What is the idea behind using binary search to solve this problem:

There is a segment of length meters, and there are $ L$ positions on it, numbered $ 1,2,…L$ , equally spaced by 1 meter apart each, in the given order. There are $ n$ balls on it, at positions $ s1, s2,…s_n$ . Each ball is either rolling to the left of to the right at the speed of 1 meter/second. Whenever two balls hit each other, both of them change direction instantly but keep the same speed. A ball also changes direction when it reaches one of the ends of the segment (position $ 1$ or $ L$ ). You are given $ q$ queries, each one gives you two numbers $ t_i$ and $ p_i$ , and you should output the position of the $ p_i$ -th ball after $ t_i$ second.

https://www.hackerearth.com/practice/algorithms/searching/binary-search/practice-problems/algorithm/rolling-balls-b8923a50/

My solution moves the ball after every second and does not use binary search:

for query in range(q):   for ti, pi in array_ti_pi:      ti = ti % (2 * L - 1)      for i in range(n):         if dir[i] == 0:             balls_pos[i] = balls_pos[i] - ti         else:             balls_pos[i] = balls_pos[i] + ti      for i in range(n):         if balls_pos[i] < 1:             balls_pos[i] = 2 - balls_pos[i]         elif balls[i] > L:             balls_pos[i] = 2 * L - balls_pos[i] 

how to calculate a damage of a 3360 pound ball of lead dnd 5e

hay so i was tinkering around and i found out that a bigbys hand can hold 420 pounds and then i thought while he is holding that lets make it bigger so i would cast enlarge/reduce to buf that to 3360 pounds so idc that bigbys hand has been dispelled its just dropped a very big lead ball (which has spikes on it) onto that poor goblin so how much damage could it do and how small can i get said ball and yes ik this is a old tactic in dnd no one realy says how much damage this could do so thats why i am here

How do ball bearings and difficult terrain stack?

There is already this Q/A on whether difficult terrains stack (they do not). And this Q/A on whether ball bearings and caltrops stack (they do not). But when looking at the description for ball bearings I realized it states:

A creature moving through the area at half speed doesn’t need to make the saving throw…

And when looking for other references to “half speed” all that existed were caltrops (with a similar description) and this bit from the “Difficult Terrain” section:

You move at half speed in difficult terrain–moving 1 foot in difficult terrain costs 2 feet of speed–so you can cover only half the normal distance in a minute, an hour, or a day…

I had always assumed you could choose to move at half speed through ball bearings to avoid the saving throw but perhaps that is not the case…

Regardless, it is unclear to me what happens if ball bearings are thrown onto difficult terrain. You would (outside of features such as the Ranger’s Land’s Stride) already be moving at half speed due to the difficult terrain but do ball bearings require it to be halved again, or is putting ball bearings on difficult terrain useless unless a creature that ignores difficult terrain?

beach ball in bluetooth in System Preference when trying to connect to Anne Pro 2 keyboard

I have trouble connecting to my Anne Pro 2 keyboard recently after the latest firmware update (see screenshot)

enter image description here

Therefore I have tried to deregister the device and register it again.

The issue is: when I tried to connect to 28-ec-9a-9b-73-53 (presumably the AP2 keyboard), the bluetooth pane was frozen and a beach ball appeared and kept spinning.

enter image description here

I have tried the ‘Clean bind’ in the AP2 utility,

enter image description here

then retry the connection but it does not work.

What can I try in this case?
