The challenge should just have two tiers:
- with disposable items (ie. stuff with charges) used
- without disposable items used
Killing something with mass use of stinging wort potion, puppet strings, Soulfire, etc. is a challenge, but at the same time there is also a challenge to soloing something without one-use items.
EDIT: Yeah I guess as Skarlorn said that's how it used to be. Haven't looked at the thread in awhile (years?) so I forgot.
