Sans doesn't feel guilty about keeping quiet about the true verdicts? The yellow halma was innocent, but she kept quiet and didn't say anything. he considers herself an accomplice to that.

Oh yeppp don't be fooled, there's boat loads of guilt hiding in there. Stuck between a rock and a hard place.

[rainingskeletons]

Sorry for the completely random question, but... Can all monsters use healing magic, or just specific ones? To be more precise, I'm asking about the potential and possibility of learning this type of magic.

By the way, if it's not a secret, which of the characters knows how to use green magic?

Healing magic is actually quite rare but the most common form of it is through cooking. Strong monsters like Toriel or Gerson are able to cast a heal from nothing

[rainingskeletons]

Has flowey been following frisk all this time since the last reset?

Flowey is kind of a distractable creature, but he did notice Frisk eventually. Due to his parasitic nature and the fact that Frisk holds so much pain and regret, he understands the truth of their situation quite quickly

[rainingskeletons]

would Nightmare Sans be able to enter Slumbertale or is he stuck watching it from the outside? I'm kinda curious now with the other AUs/multiverse thing

Since the Slumber!universe is maybe a little more uh "sentient" than most of the other universes, I think it might be pretty hard for him to enter actually (including other intruders from outside AUs) . Through various protection mechanisms the magical core (aswell as certain safeguards) has some criteria of who is allowed in or out... That being said, if someone from outside has knowledge of these mechanisms then they might actually be able to find their way inside....

[rainingskeletons]

People better appreciate this AU’s Grillby because I never see enough contents of Grillby AU’s . GAWD why does skeletons have to get all the fans while the hotter ones are left out (pun intended)

YOU UNDERSTAND... We have to be the change we want to see in the world

( I am totally normal about him...)

[rainingskeletons]

Wow, what a cool fire guy (Grillby), can I have your autograph sir?

He’s not very good at it…

[rainingskeletons]

Hello! I really like your au and its characters. However, I don't quite understand how Grilby hypnosis works, can you please explain it to me?

You’ve ever sat infront of a fire and just… gazed at the flames for a long time? It can give you a really calm and soothing feeling.

Grillby’s fire kind of takes this feeling and amplifies it into a hypnotic state.

[rainingskeletons]

i have seen some of your comics, and I got to ask (sorry if this has already been asked/answered), but is sans narcoleptic? I know that he's a sleepy dude, but it seems like he falls asleep at random.

Yep! He’s narcoleptic, especially if he’s been using magic a lot

[rainingskeletons]

I just want to tell you that I discovered this comic today and I binged the entire thing from chapter 1-6. This comic is really good and I can't wait to see where it goes next! 👍

Welcome! So wonderful to hear that you found the series binge-able. That’s one of the highest compliments in my book :D

Wanted to draw a favorite au of mine, Slumber!Sans!

Slumber!Sans belongs to @rainingskeletons

[fernfoxes14]

SlumberLust…. Would their ship name technically be somnophilia…? Like if you think about it… nevermind…

Rare pair number one!

Slumber - rainingskeletons

Lust - community

@rainingskeletons cough cough... hi... there... I was scared to tag you but alright fine

[rainingskeletons]

Don't be scared to tag me! Remember I believe the shipper heart should be free haha

[meowzcw]

Hi, so I wanna ask. Are you okay with letting your characters be used in crossover stuff? And also when will we get to see Chara ( Sorry if this question is kinda redundant)

Yeah, I think crossover stuff is really cool! And we will be seeing Chara in bits and pieces as the series progresses :3

[rainingskeletons]

Actually now I have a question, why didn't he just float above Frisk and blast them during genocide? They're really short, at most they can jump 2ft maybe 5

I think he totally would haha, but also remember that using magic makes our skeleton buddy really tired. He's gonna have to come down eventually... Also I kinda think that by the time Sans fights Frisk in geno, Chara has gotten really good at using Frisk's soul and the power it might have in a world who reality is so maluable. Making some flying knife attacks that can hit far away is well in the scope of Chara's power.

[rainingskeletons]

Not a ask but wanted to say I’m honestly so glad my underrated king Grillby is given the admiration he deserves

I also just love seeing other peoples interpretations of Grillby as a character, whether it’s his personality etc 

And I honestly can’t wait to see more of him!

Yesss, I love Grillby so much and I love how many different interpretations there are for him. It makes him such an interesting character to explore!

[rainingskeletons]

Hello dreamers, will try to get you an update tomorrow!

There’s a sequence I’m having a little writer’s/artblock on so it’s been taking some time but thank you so much for your patience!
