Character creation and worldbuilding

It's posible I would call this a black dragon turned Volcanic, but either red or black works.

If it is volcanic - even better I would then pick a different very rare item, one that is indeed useful, not just story based.

Finished up & submitted my character mechanics.

I submitted my character as well, though his spell list is a mess and I could change it on any long rest that will be challenging experience

Now that The custom character sheet features Adam recently had in development are set into action I'd like to ask that you allow me to submit a custom character sheet!
Avaris Custom Sheet

No worries - Custom character sheets are now also allowed. I'll look over the characters that have been submitted so far in detail tomorrow.

Vanquishing a volcanic dragon definitely gets my seal of approval!

by the way, my character is automatically imported from beyound, it did ignore at least "Cauterizing Flames" which I had to add manually. There were also few more mistakes I've just fixed. But I bet there may be more minor mistakes I may need to fix when it will be time to use my features.
If this of any help, link to the source
And I assume I do not need to specify that I get all the spell components with a cost associated for casting, such as "an object with the image of a dragon engraved on it, worth at least 500 gp".

I see also import failed to process al of my huge list of spells known, will think how to solve that later

Perfect! Submitted the Custom Sheet for Avaris!

Oh wow I hadn't thought of using the custom sheet. I shall go update mine now.

Ooh, the custom sheet is very shiny! Looks like all the characters are coming along great.

GreyWord - yep, you can have any costly material components you need for your spells. You've had plenty of time and resources to acquire them. For consumable components, there's no limit per se (and you can always acquire more if needed), but consider how many you would normally carry on your person. The import definitely didn't seem happy about your spell list, but everything else looks good to go.

KoldikSteelskin and SvanDerh - Avaris and Altea look ready!

BedzoneII - I'll wait for your updated custom sheet, but I should have enough to go on.

Thanks everyone! I'll kick things off as soon as possible, should be in the next couple of days. If you have any remaining questions or suggestions about the world or your character's place in it, feel free to post here.

I've cleaned up upcast spells from char sheet and did a small adjustment to spell list.
I have a rules question however. For lvl 20 characters invisibility, magical darkness and such could be used by both PCs and enemies. I've seen different DMs interpret inability to see creatures and environment in most different ways, could you please define what do you as DM think about it.

P.S. I will certainly try to properly role-play situations when my PC can't see something and will limit his actions/decisions. I just want to know if DM is willing to enforce me doing so.

Am making a bit of a mess with my customing of the character sheet, but I've submitted it anyway as a placeholder and will continue to tinker with it.

Great questions, good idea to hash some of this stuff out before it comes up in-game. Here's how I'd generally play it:

1. Out of combat: Stealth checks (and skill checks in general, really) should be made when there is the potential for a dramatic event. For instance, an invisible character moving through a crowded market wouldn't need to make any checks to pass unnoticed - even though people in the crowd might "notice" an odd sound or being bumped, it doesn't matter to the narrative outcome of the scene. If that same invisible character were then to try to sneak into a tent that had guards posted outside, they would make their Stealth check against the guards' passive Perception (generally with Advantage unless the guards had special abilities like Blindsight or Keen Smell). If the guards were already alert to the presence of an invisible person in the area, they would instead oppose the character's Stealth with active Perception checks.

2. In combat: A creature that is invisible but hasn't used the Hide action is not trying to conceal its location, and can be targeted normally (usually with Disadvantage on attack rolls due to being unseen). An invisible creature which uses an action to Hide is harder to target: if your Passive Perception is high enough to beat its Stealth check then you know where it is; if not, you can either take the Search action to try to locate it (contesting its Stealth with your Perception) or guess at its location. If you confirm its location (via Passive Perception, with a Search, or a successful attack while guessing correctly) then you can communicate that to your allies, who can then target that same area.

As far as moving through areas of magical darkness, this would impose the Blinded condition. Being Blind doesn't impact your ability to navigate per se, but there may be circumstances where it's appropriate to impose a difficult terrain penalty and/or give away your location based on what's in the area.
