I've scoured the forums for details on this but only found this thread which seems inconclusive https://www.project1999.com/forums/s...=cripple+spell

My questions are:

Is cripple line worth casting if you have the mana?
Does it decrease mob damage?
Does it increase dmg done to mob by melee?
Are there situtations/encounters when cripple is useful?

Thanks for coming to my TED talk on cripple. Thoughts & experiences welcome below!
