Invisibility, Spell Effects, and Dice questions

These might have been answered, but I can't see a way to search the forums. These came up as we got ready to run our first Roll20 campaign: 1. Is it possible to set a creature (or character) invisible, so that no one (or only certain people) can see the marker? I know the GM could move a creature to the GM layer, but what if one player can see invisibility and the other can't? How about players hiding a marker from the GM? 2. Are there any spell effect templates available? If I can a fireball, is there a template I can plop onto the map to show where I want the effect? 3. I know you can do a /r 1d100 for percentile rolls, but is it possible to do a true percentile roll using 3D dice and 2 d10s? I checked the dice reference but didn't see a way to do it. Thanks!

Not without an (in my opinion) unreasonable amount of work. You could duplicate the page and use the Split the Party feature, copying actions on each page over to the other. It would be possible to write an API script to accomplish this, but nobody has done it yet to my knowledge, and even then, utilizing such a thing would require Mentor status. Toasty Thaumaturgy has a bunch of differently shaped and sized fire-looking templates. Chaotic Conjuration has a bunch of templates for other effects. The 3D dice won't be helpful in this (all of the 3D dice will be in your default color), but you could certainly use 2d10 to display 01 through 00 in the chat. [[d10-1]][[d10-1]] would display two inline rolls, each in the range [0..9]. As they're adjacent, they'll appear roughly in the classic d% format. You won't be able to get 01, 02, 03, 04, 05, 06, 07, 08, 09, or 00 to show up that way with a single roll without the API, though. That means that, if you want to use a successes roll, you're stuck with something along the lines of d100>50.

Thanks! I appreciate the help, and the links to the templates.

Jeremy, Brian is correct but you're better off doing percentile expression as [[{1d10*10}+1d10]] -Jon

I tried that, and it works, except for when a '0' is rolled. Then I get something like 105 instead of 05. But the first one also did something similar. But I think it will work well enough. Thanks!

It would be cool if d100 was a 3d dice option!

I'm not really sure why it isn't. Seems like it wouldn't be a big deal. Maybe for a future release.

Because we already have situations where the lesser sided polyhedron's have trouble sticking their landing. A d100 would roll around on screen for a very LONG time. You're basically rolling a golf ball at that point. Special-case the d100 to roll d% with the 3D dice (or implement d%)? Then you're dealing with two decahedrons.

You're basically rolling a golf ball at that point. I was just thinking the d100 would roll two d10s, one of which the double-digit '10s' dice. Just like real percentile dice. Granted, the above methods can work well enough.

Well it screws with the average of rolling 2d10s in the players favor but you can adjust my formula to [[{1d10*10}-1d10]] and you will get a 00-99 % range. On the topic at hand, you could just roll 2d10's in the 3D dice but I am on the side of not having a true d100 animate in 3D dice. -Jon

Yeah, a true 1d100 wouldn't work, I agree. Probably would roll around all day. I'll give your formula a shot. Thanks!

You're basically rolling a golf ball at that point. i used to have an actual d100. Kristin's right, it is the size of and looks just like a golf ball :) the manufacturer had to put small pebbles or something in it to slow the thing down enough to actually land on a number.

About 40 years ago some wag was selling a physical D50 at D&D conventions. It rolled off the table 90% of the time, so it became a game of "I think it went under there."

The best d100 I seen worked like a magic 8 ball.
