At what point do levels make up for lack of more powerful magical items? For example: Could a 16th level party handle a 10th level scenario with "lower powered and fewer magical items..pretend just with some potions and scrolls to hit DRx monsters?"
Can a 20th level character with no magical items survive a 10th level scenario?
Thing is, it varies heavily from class to class, build to build, and encounter to encounter.
Your average CR 10 encounter is six CR 5 trolls.
Not that tough, right? except they regain 15 hit points / combat round.
Now, the level 20 fighter gets 4 attacks / round. +20 / +15 / +10 / +5.
they can carve up one of the trolls with minimal effort...
Except.. the trolls keep getting back up.
Regardless of how much damage they do to the trolls, even if the trolls are below -10, they still regenerate, and still get back up. Unless they can build a fire or dump bottles of acid on the trolls.
If he doesn't know what trolls are, or how to defeat them, or hasn't prepared for them... the trolls will eventually wear him down, overwhelm him, and kill him.
Conversely, A 20th level wizard could just hit the trolls once, with a maximized fireball. Boom. The trolls are dead. if not dead, then severely wounded. a burning hands, acid arrow, or any of a wide plethora of other burny / melty things that the wizard has at their disposal will be effective.
Oh, and the 20th level rogue will get wiped out. He might get three sneak attacks in, but they would all be against one opponent, and then he would be rended asunder by the other troll, until the first one regenerated enough to stand up. doing 1-3d6 + 1-3 x str isn't enough for a rogue to stop a foe that regains 15 hp / round.
