Hey everyone, just wanted get a feel from the community for a one shot encounter I promised my group I would run for them.
Scenario:
-I am running as DM and my group wants to fight a one off battle as level 20 characters with lvl appropriate gold division, there are 5 of them.
-the field will be an open arena 400 feet long 275 wide and 125 tall.
-anything available in hero lab is approved for making characters that is not 3rd party
- all party members and monsters will start out prebuffed.
-very experienced group average years of gameplaying under their belt is 7 years, ranging from 1-15 years.
- double blind set up. They don't know what they fill face and neither do I with the exception, they are good/neutral party and enemies will be neutral/evil aligned.
: questions: what is an appropriate CR level for the above criteria?
- what changes can/could be made for a balanced and enjoyable battle?
- what difficulties would you expect to run into that could break the battle or make it one sided?
:Personal opinion/self answers;
- I think a CR 26 would be appropriate
- seeking opinions
- 3 dimensions will be in full use. Certain protection spells or banishments for demons/devil's.
I appreciate any help or I sight y'all can provide. While I am an experienced gm, I have never run a one off battle before at such a high level. Also keep in mind these players will be min maxing to the extreme.
