Darn, I made a mistake!

We all make mistakes.  Even your DM makes mistakes.  So, first things first.

1) Don't beat yourself up about it.
2) If possible, clean up your mess.

Lets talk about some types of mistakes you might make, that *I've* repeatedly made.  My suggestions about how to deal with mistakes are how *most* DMs would rather they were handled.  If your DM wants to do it differently, she's the boss.

A) I clicked an attack roll, or double clicked an attack roll, or triple clicked an attack roll.
   Fix: if you weren't supposed to make any attack, everyone ignores your roll.  If you were supposed to roll once but you rolled twice (or more) the first roll is counted and the later rolls are ignored.

B) I clicked "Performance" instead of "Perception" or "Stealth" instead of "Survival."
   Fix: DMs are split on this, some want you to roll the right check, others take your d20 and change the modifier.  Ask before you re-roll.

C) I rolled an attack roll, but the creature wasn't targeted.
   Fix: Drag your die roll on top of the creature in the combat tracker, read the result to see if you hit

D) I rolled the damage dice even though I didn't hit the creature.
   Fix: Hold down the Ctrl key, and drag the damage on top of the creature in the combat tracker. Creature healed.

E) I didn't click on the +2 or -5 modifier before I rolled the attack.
   Fix: Click the modifier, and drag your die roll on top of the creature in the combat tracker, read the result to see if you still hit.

F) I didn't click on the ADV or DIS modifier before I rolled the attack
   Fix: Roll again, if you had advantage a hit either time will be a hit, if you had disadvantage a miss either time will miss.  Roll again even if you hit the first time unless you crit on your first attack, cause you might crit on your second one.

G) I rolled damage but didn't add my Sneak Attack/Hunter's Mark/Colossus Slayer effect
   Fix: As far as I can tell, you can't do this one on your own.  Roll the additional dice, and inform the DM of the additional Damage, and tell her the damage type (piercing, non-magical).  She'll have to clean up your mess.

H) I rolled a critical hit, but the creature wasn't targeted.  Now if I target the creature and roll damage, it will only do regular damage, not critical damage.
   Fix: After targeting the creature, hold shift while you roll damage -- it will auto-crit.

I) I added an effect to myself (or others) when I shouldn't have, or I added it multiple times, and it should only be listed once.
   Fix: For most DMs you will have to ask the DM to remove the effect for you.  However, if your DM has the Remove Effect Tag Extension loaded, then you can remove the effect yourself.  How this extension works is that you create a new effect that is identical to the one you placed except at the very beginning you type "REMOVE: " see my example below:

Do you have other or better ways of fixing mistakes?  If you let me know I'll add them to this list with credit unless you ask to be anonymous.

Effects in Fantasy Grounds: An introduction and some advice.

So you've played a game or two of D&D 5e on Fantasy Grounds.  You've clicked on all of the UI buttons, and see what they do.  You know how to open up the Calendar, change the color of your Dice, how to drop dice in the Dice Tower (unless your DM doesn't use a dice tower).  You can find a map that was shared and you closed.  You know how to drag and drop inventory items from the Party Sheet Inventory tab to your Character Sheet Inventory tab.  You know how to roll initiative, ability checks, attacks, and damage dice for weapon attacks.

The list of things above are things a bright person can pick up with some experimentation and some free time.  You're playing D&D, you're a bright person.  If you don't know how to do these things, spend some free time and experiment.

But there is the whole effect thing.  This is something that non-programmers will not pick up by experimenting.  If you *are* a programmer, then check out:  http://www.fantasygrounds.com/wiki/index.php/5E_Effects

For the rest of us mere mortals, recognize that this will be a long process.  I've been playing in FG for almost a year, and there are still lots of things that I don't know about effects.

If you're not really a spell caster, you might be able to do with very few effects.  And most of the spell effects will automatically populate.

Most of the class ability effects (and other awesome info) can be gotten from:

So for example if you've got a Barbarian, and want a rage effect, you can go to the "A Barbarian" page, download the *.xml file and drag and drop from the "A Barbarian" actions tab to your character's actions tab. Be sure that you read the original post because even more important than the effect is information about what abilities and traits *can't* be automated in FG.  That will save you a lot of hair pulling.  Also note that you'll probably have to adjust most of the effects because they're set up for a Level 20 character, not a Level 1-3 character.

But if you're a Ranger with Hunter's Mark or a Rogue with Sneak Attack damage or a Great Weapon Master/Sharpshooter feat person.  I suggest that you *don't* create effects.  Instead create separate Weapons for each of the things you'll be trying to do.  Here is an Example:

This is from my Fighter6/Ranger2 with the Sharpshooter feat.  I've created four separate weapon attacks instead of applying effects for the Sharpshooter feat and for my Hunter's Mark.  Why did I do that?  Because I can decide before shooting which situation I'm in, and then just roll the Attack, and if it hits, the damage.  When I had effects, I would make an effect mistake about 33% of the time, and when I would it would mean that the DM would have to remove my bad effect, or adjust the damage.  This setup makes mistakes much less likely.  If you know about the Oathbow, then you know that once per day I can name someone my "Sworn Enemy" and do a *lot* more damage.  I decided to keep my Sworn Enemy as an effect.  I only use it rarely, and when I do, the fact that I'm using it is foremost in my mind, so having a Sworn Enemy effect doesn't create errors the way that Hunter's Mark or Sharpshooter effects would.  It may be the case that creating all possible combinations of damage options is too unwieldy, but for the type of damage effects that are linked to weapon attacks that will occur almost every round -- creating separate weapons for each of them can create a smoother time for you on your round, and for your DM.
