Unstable Curse III
Medium Length Challenge - 1 ~ 5 Hours - Depends on Activity
Strategy
The Goal of this Challenge: (by recommended priority)
- 100 Insight
- ~100 Wisdom
- 25 Intelligence
- ~100 Spellcraft
- ~Patience
Use 
Magic Missile to replace any unwanted Spells, and to get the desired combos, or to switch out pets (especially with a Devourer)
(Putting it on MM on Reckless Autocast will automatically use it until switched out for a new spell)
1) Focus on leveling up your Pet with: (Recommended using with Interrogator active.)
Would Not recommend 
Fire Ball, as to not lose current Pet.
Another quick way of gaining pet experience is to charge 
Arcane Infusion with a Spellhound or Arcanaworg active and cast it under the effect of 
Unclean Knowledge. The incredibly high shard cost means the Spellhound and Arcanaworg gain an obscene amount of experience from this combo. This same logic can be applied with 
Silence instead to make ever spell cost a lot more.
2) Void Mana is easily acquired with Voidfiend:
Hellrage
Void Prison
Void Radiance- Collecting Void Entities
Void Syphon
- Alt method: Anima Construct + Void Radiance +
Void Lure + Void Prison + 
Void Automaton
3) Autoclicks can be done throughout the challenge, and you can use any Summoning Spells, with Necromancer's and Druid's being the best.
