I'm willing to adjust it...
They have already fought Pestilence and War.
I told them each one is going to be more difficult, so Death is going to be very very hard...
There are 2 diviner wizards (1 is level 20), 1 warlock (level 20), 1 eldrich Knight, 1 war cleric, 2 fighters (1 is level 20) and 1 arcane trickster.
The others are level 18.
All are decked out.
5 PCs are living artifacts (they have absorbed a shard into their bodies which gives them all 10 ft auras, and immunity to Charm and Fear- so that means those that cast magic are considered to be spells from an artifact).
The battle takes place on a round platform 40 feet above the ground and balanced on a pyramid.
Famine is unaffected by the balancing.
When the players attempt to get on the platform, they have to make a DC 20 DEX save or fall and roll off.
If they fail 3 times, they take a point of exhaustion and falling damage.
Here is what I have so far...
Please let me know how to adjust it
