Oh, you're very welcome! You're doing especially well for someone with English as a second language. I'm quite gifted with English competence, so I notice these things instinctually.
Vestments: Costume, eh? I suppose that that works. I still think that they should be based on fine clothes, but, hey, it's no big deal.
Variables (e.g. gladiator weapon, merchant proficiencies): Aye, I agree. To me, simply listing a "variable item" or "variable proficiency" and referring someone to the appropriate page so that they know what to pick from is more convenient and complete, but it's no big deal. People really should know the contents of the book before relying on auto-fill forms, in the first place.
Guild artisan/merchant thing: Fascinating! It was part of one of the bugs that you fixed. When switching between guild artisan and guild merchant, the previous version was erroneously adding the business options of both to one list. Traders, caravan masters, and shopkeepers were listed in the guild artisan businesses (with all the others), and all the others were listed in the guild merchant businesses (with the three merchant businesses) when switching between them. It had to have been part of the bug in which features were not being removed when switching between variant backgrounds.
Gladiator: That text is referring to the notion that any character can have some experience in any skills (After all, backgrounds are meant to be general patterns, not cookie-cutter explanations of entire backstories.), but that one's entertainment specialty is gladiatorial combat. Regardless, it's no big deal. If it's too much work to change it, that's that. It's currently functional, and that's what matters.
Equipment: Ah, that's fine. I was just expressing my preference in case you didn't care one way or another. Since you have a preference, by all means, keep it that way.
Independent DCs: There's not much of a "need" for it unless writing custom moves that have their own DC calculations, and an auto-calculating sheet doesn't really have to satisfy such things as that, but it's handy for making it look nice after one has accidentally entered "CON" as a DC modifier for barbarian abilities, then realized that barbar abilities don't even have DCs, haha! Anyway, that was an incredibly minute nitpick, but I appreciate your cooperation with it.
Multiple weapons to auto-add: I was just using Dagger x2, Handaxe x2, and such like that in the weapon name fields. Just now, I tried putting "x2" in the description fields, and that didn't work, either.
Weight = quantity * base weight suggestion: Oh, hey, you know, I was thinking about suggesting this. I'm glad that I'm not the only one who thought of it, because it slipped my mind entirely. Thanks, Headbomb!
In the Changeling racial trait, you have a typo of "O" where there should be an "I".
One of your tooltips says, "Alternative, setting-dependent, race names . . ." The second comma should not be there. I must note again that your literacy is admirably higher than what I usually proofread. This looks amazing.
Wow. You have the dragonborn breath weapon auto-calculating. I love you.
Svirfneblin Magic: "Intelligence is my casting score for these spells." That should be tacked on to the end. I know, I know: That part of the PDF is formatted oddly, so it's easy to miss. It's strange, right? Don't feel bad about forgetting it.
Rock Gnome: Wow. Very thorough. The last comma in "Clockwork Toy: Animal, monster, or person," shouldn't be there. There should be an "a" before "random direction," and the "produces" should be "produce" in the Fire Starter description, under the current phrasing.
Suggestions:
-When the Eladrin Misty Step and Tiefling Hellish Rebuke are added, also add them to the list of available Bonus Actions and Reactions, respectively.
-List the Tiefling Hellish Rebuke with "(3d10)" or "(Lv2)". It's very, very easy to overlook the fact that that spell is cast at second level, so it burns harder, and players could use a friendly reminder. Likewise, the water genasi Create or Destroy Water could use a "(20 gallons/35')" or "(Lv2)" notation.
-Could we have a "Powerful Build" checkbox next to carrying capacity? It's not like the math is too hard that we can't get along without this or anything, but, see, my DM doesn't keep track of encumbrance (Yeah, that's a bad idea. It's not my idea.), so he has house ruled Powerful Build to be a +1 to AC. Likewise, if DMs give out doubled carrying capacity as a result of magic items or other rewards, if custom races are involved, or if someone somehow has a permanent Enlarge spell on them, such a button would be kinda' convenient.
Thoughts:
-Speaking of racial features, you have the water genasi spell listed simply as "Destroy water." I think that adding a "Create/" at the beginning of the name would fit just fine, right? Hm, testing it out, it's just two letters long enough that the text has to resize down. Maybe just "Create/Dest water (Water genasi)" or "C/D water (Water genasi)" would work? Just tossing out ideas, here. Again, I stand by my feeling that people should read the book/PDF, then use the auto-filler with the understanding of how it works already in their head, so this is no big deal, but it's a thought.
-What would it look like to have a second DC-calculating field? I mean, you know, in case one multiclasses or uses a race with features that have DCs that are on different scores than their class' features (e.g. dragonborn sorcerer, fire genasi warlock)? As far as I'm concerned, DC calculations are easy enough that one reminder should be more than enough, especially if you're multiclassing, because you should know what you're doing if you're multiclassing. What I'm saying is that this is not a feature that I'm interested in suggesting, but it's a thought that occurred to me, and I want to hear how you feel about it.
This work continues to impress me. Keep it up, man!
