There are so many comments that appeared overnight (thank you!) that individually addressing them would either involve a stupidly long post, or a stupid amount of posts. So, firstly, I have read every comment, I assure you, and here are some general replies:
1) I made an error on the Divine Soul's empowered healing, the error is now corrected
2) I'm of mixed opinion on whether I underrated the Conquest Paladin's fear ability. I'm going to think about it.
3) I have made changes to the Summon Greater Demon spell thanks to some great feedback from readers. I'm still rating it green, but it's close to blue. It's good, but I want to see it in play.
4) Questions were raised on whether a TWF College of Blades Bard needed Warcaster since they can use a weapon as a focus. I've linked the relevant official information in the guide
5) Shadow of Moil: Yes, I've almost certainly underrated this spell, yes probably by multiple rating points. I think I misread the "heavily obscured" portion of the spell, this requires some thought about just how big a
deal this is. Expect a re-evaluation soon. The Sky-Blue I keep getting told to change it to probably isn't going to happen though.
6) Healing spirit: OK, this would require a lot of room to completely cover, but I'm happy with my "good" rating. Yes, I'm aware Jeremy Crawford aknowledged "they were keeping an eye" on it. Yes, it's good out of combat healing, I mean as far as healing spells go, as good as it gets. I do think that the excitement is overblown though. I think it's good, but not broken. It is my expectation that eventually, the hype over this is going to blow over. I could be wrong.
7) Gift of the Ever-Living ones (Warlock invocation) maybe should be orange, because there are some combos that can improve effectiveness. I'm considering it.
8) I made a mistake on the Tipsy-Sway redirect ability for Drunken Masters. It has been corrected
9) I have re-evaluated Steel Wind Strike. I'm still happy with its current rating. Maybe I'll take it at some point and give it a try, but I'm not expecting the dramatic success that I've been told I should.
10) It's been pointed out that I didn't mention that Samurai + Elven Accuracy work well together. I don't think this needs special mention, because there are lots of ways to get advantage.
11) I realize that the color scheme (or color coding in general, or color coding non options, or providing different colors to abilities gained at the same level) has a definite divide in popularity. I really encourage everyone to read the text, it will give you a much better and more nuanced evaluation than any rating I could give. Frankly, I could almost give up color coding altogether, as any feedback I get is universally negative on it, but it helps me organize my own thoughts on things.
12) (This one is for Mellowred) To be clear, I use the brown rating exclusively for the worst traps. Things that are objectively much worse than other options, so you actually screw yourself over for using them. Changing damage type from piercing to radiant (as a non-random example) is generally useless, but doesn't actually make it worse. Normally, that would be a red rating, but in this case, it actually could be really useful in certain circumstances (say you are fighting a lycanthrope for example). Things that are normally useless but there are specific circumstances where they are quite good get rated orange. That's why the orange rating on that ability. Now we can discuss various circumstances of Ki points for additional attack and magic weapons etc, but we are really just looking at an ability that we both think isn't very good, on a subclass we both recommend against, and our disagreement is only about how strongly we don't like it. How much time should we invest?
13) I don't rate by "Best in class". This isn't new for this guide, and I've explained in much greater detail why somewhere in the comment section of my Wizard guide when talking about higher level blast spells.
14) I made a mistake on Maelstrom, it has been corrected
15) Circumstantially good spells get an orange rating. No reason to tell me, "If you are playing X, and Y condition is present, this spell is blue!", nope, it's orange. That's what orange means.
16) "Tortle" was someting unheard of to me until I read the comment (ToA apparently), and it's not referenced in Xanathar's to my knowledge, which is why it's not in my guide.
17) Please understand that we aren't going to agree on everything, we will never have group consensus, this is subjective stuff. I am always glad when someone disagrees and they explain why they disagree, but understand I will not always be persuaded. I still appreciate the feedback. I can't reference every "I can't believe you rated X this way", there are too many. I do read every comment, and I do consider your reasons. Sometimes I do change my mind, but often I've already considered what you mention, or I simply am not persuaded.
18) Metamagic + Cleric spells: This is not something I gave much (or apparently enough) consideration to. I will do some research, and may or may not change ratings.
19) As for Divine Soul being great because you can select the best of 2 different class spell lists, that is not persuasive at all to me. A regular sorcerer can't even get the all the best of one spell list. Imagine I present you with 3 stacks of money. Each stack has $1,000 in different denominations. I tell you that you can select on stack to keep. Is it that much better if I gave you 6 different stacks to choose from? Or 60? Now granted, there are some instances, and some builds, where the spell on the Cleric list is simply BETTER than anything on the Sorcerer list, but I really don't think it's all that commonplace. For the most part, I think the Sorcerer list is better.
20) In response to Peryton's being the best option available with a small character (for the find greater steed spell), I've been trying to find the rules for what size mount you can use when you are small (or any size for that matter) and have been unsuccessful. If a small rider can ride a large mount, I do think Pegasus and Griffon remain the superior choices. However, if I could be pointed to the rules on mount sizes vs rider sizes, I would appreciate it.
21) In regards to Homunculus, to a large degree, I find using it as a "scry" alternative is very similar to using a familiar as a "scry" alternative. Useful beyond 100' though, but to a large degree, redundant. As for comparing it to scry, your enemies or traps, or environmental conditions can't see or kill your scry sensor, which is kind of a big deal. Homunculus has a +2 stealth and cannot turn invisible.
22) If something is circumstantially useful, but those circumstances are so rare that in most campaigns, they will never come up even once, that's not orange, that's red.
23) Rofel Wodring: I don't think Unicorn Spirit and Goodberry interact the way you think, or at least the way I read it. As for Demon true names, generally, I'm thinking of these things as combat spells. Now if my DM allows me to have the Demon take some useful combat action AND tell me its true name at the same time, that's a no-brainer, but I'm not sure I would be able to do that. For the most part, I'm thinking that spell is best just throwing a Demon into the midst of the enemies and have it lay into them and make itself a prime target for attacks. Not really thinking about it being particularly useful for an extended time.
24) A familiar cannot attack. Now by RAW I think you have a good case to say that activating Dragon's Breath isn't an attack action, so it's fine. Not sure my DM would agree, RAW or no.
25) Nodachi is a great weapon for Samurai, thanks!
Thanks everyone for the feedback! I read every comment (most twice), but if I missed commenting on something you were looking for my specific comment to, please comment again. Keep it coming!
