The spell mighty fortress is very specific about the size and shape of the castle it makes, but not about where walls are connected. Both are 120' square areas with four 20' turrets connected by 80' walls, but the second one you get more interior space and can access your turrets without leaving the outer walls.

You can make it permanent if you cast it 53 times, and by the time you hit level 15, 500gp for a week of downtime with comfort and security is occasionally worth it. Our druid/cleric regularly casts greater restoration rather than wait for me to prepare remove curse the next morning.

As I've pointed out in other comments there's a specific rule for damage past 0 HP. It's called “Damage at 0 Hit Points.” under the Death Saving Throws section, and it doesn't say anything about it getting cancelled out.

The touch of your shadow-wreathed hand can siphon life force from others to heal your wounds.

Doesn't say "exclusively from others". Without casting this spell you couldn't do that normally.

It also says,

On a hit, the target takes 3d6 necrotic damage, and you regain hit points equal to half the amount of necrotic damage dealt.

No qualifiers about the target having to be a creature other than you. It just has to be a creature within your reach.

Also as regards:

As a DM there’s a few ways I’d consider to stop this being entirely game-breaking:

Do you also ban death ward and healing word? What about wizards who dip a level into virtually any other spellcaster or take a feat for a healing spell who can do this kind of thing without even having to make an attack roll or take necrotic damage?

Vampiric touch counts how much damage you deal, not how much hp the target loses.

It's definitely a flavor fail, but unless you houserule in a cap to damage dealt at 0 hp, (and houserules for how to handle massive damage and the rules for being dealt damage at 0 hp that would be affected,) there's not a limit to how much hp you gain based on the hp of the target.

You're still dealing damage, e.g. it could kill you from the massive damage rule if you dealt enough. Vampiric touch counts how much damage you deal, not how much hp the target loses.

I personally just rules lawyer back twice as hard.

• Well, technically revivify requires you to target a creature not the corpse of a creature…
• Actually detect magic doesn’t exclude itself, and the passive detection is pass/fail, so unless you’re immune to divination…
• Oh, the demi-lich got errata’d to have more hit dice, but they never “corrected” the default hp based on the special Undead Nature trait, so now it actually has %60 more hit points than the stat block would imply.
• Sure, freedom of movement lets you escape these non-magical restraints, but you have to spend 5 feet of movement to do it and your speed is currently 0.

A fair chunk That Guy’s tricks depend on a lenient or permissive DM/cherry-picking the most favorable rules & interpretations. If you don’t shadow-patch a bunch of fixes to make things work how people expect them to the game breaks down. If they want me strictly following the rules I’m happy to oblige, but I’ve never seen a powergaming munchkin who could withstand the amount of nerfing actually playing RAW causes.

It should fit pretty well. 😁 The audio matches the subtitles for all but one word.

This is from a show called Dirk Gently’s Holistic Detective Agency. This is an edited clip from the 2016 version.

Edit: I put together a brief clip of a scene more representative of the tone of the show, to give people an idea of what they’re actually in for if they go looking for it.

Loving it so far. I haven’t had a good old fashioned dungeon crawl for quite some time. Megadungeon in 5e does throw me off occasionally, but we’re doing pretty well. Only one PC died so far, but the druid/cleric revivified him before it stuck.

I’m the party wizard/necromancer/note taker and sometimes I do make maps.

Heavy Spoilers for floor 9.

We got the initial map image from the DM. This is annotated and updated.

I’m in the middle of the 5e version at the moment. We’re level 11 and have reached floor 9 so far. We started December 1st of 2022 and play at least once a week.
