I ran The Black Cabin encounter from Icewind Dale:Rime of the Frostmaiden last night and my players and I had a blast. It's a very well designed encounter with an interesting premise that works just as well as a standalone one-shot as it does in the context of the full campaign. It made me wonder what other encounters from full campaigns might make great one-shots. The Goldenfields attack from Storm King's Thunder and Chapter 1 of Waterdeep Dragon Heist come to mind as possibilities, can you guys think of any others?

Thank you to everyone who offered help with my other Artificer rules questions, it was appreciated. The mod's in beta testing right now and I'm trying to clean up little rules-related things that testers have asked about, so I have a couple questions about Battle Smith's robot dog(*):

• Can a Steel Defender use an Opportunity Attack? If so, can it do so with Force-Empowered Rend, or would it just be a "basic unarmed attack" (i.e. 1 damage)?
  • Followup: If a Steel Defender can do OAs, that would prevent it from using Deflect Attack, because both are Reactions, correct?
• A summoned pet should have access to all the 'typical' D&D character actions, like Help or Hide and so forth, correct? Even though they're not explicitly called out (or removed) in its stat block?

Sorry if these are dumb questions, but googling wasn't providing answers that were up-to-date. Thank you in advance!

The spell text for "Regenerate" does not mention the creature to have to be willing, and there also is no saving throw. Yes the casting time is 1 minute which might make this difficult to do in combat, but maybe you could hold the unwilling creature in place for that amount of time.

If a player wanted to cast regenerate in a hostile way to regrow a body part the enemy does not want regrown, would you impose a saving throw/a series of saving throws as homebrew?
