So you can just cherry pick a heap of high AC opponents and claim victory lol.
Thats not how I design encounters. It'll be a mix. I dont design encounters to kerb stomp PCs, but to challenge them (and occasionally to allow them to show off abilities).
Also 5th level is not really at the tipping point of these feats its still reasonably low. You will use them on occasion but you will not have maxed dexterity to 20 for example or have that many 2nd and 4th level spell slots available.
Alright, how about 9th level then? Thats enough for 2 ASI (3 if human, 4 for fighters). More than enough room to max a stat and grab one of those feats.
Also how would we settle how many encounters and short rests? 6-8 encounters, I would suggest 7 with a short rest available after the 3rd encounter and 5th encounter?
It'll be 6-8 with opportunities to short rest. Im sticking to the guidelines in the DMG (with some liberties taken of course; its an art not an exact science).
Default array, point buy, multiclassing? RAW I get to roll dice as well.
Yes, yes and go for it. All published WoTC books, and I'll even throw you some magic items as well. Ill pick a few when I see the PCs.
HP and stats as per the book. Just let me know any feats, or class choices youve made (manouvers, F/S, key equipment, spells known).
I picked 5th because its quick, but I can do 9th as well.
In any event this is a completely artificial thing. I use real games of D&D using the prepublished adventures both 3pp and WotC produced and they do not use customised encounters to shut down or metagame against whatever 5 members of 5th level I conjure up.
Im not trying to 'shut down' or 'metagame' anything. DMs cant metagame, and they certainly can't during encounter design. Their job is do design encounters that challenge and entertain the players (and their characters) as presented.
Im just trying to show you that the encounter guidelines in the DMG work. Ill take your party put forward, and design an adventure, following the guideleines in the DMG that will challenge that party.
Not kill them. Not kerb stomp them. But not be a cakewalk either. A challenging adventure using the DMG guidelines for encounter design.
The point isnt to troll you. Its to show you how the system works when you know how to use it.
