Hello, maybe a bit of a geek question , but could i use Rage to reroll and if the rerolled dice sucks, i could then kick in Accuracy Corrector to cancel the rerolled dice? (Using it on Mist Hunter with 4-LOM)

Yes, you could. But usually stuff using Accuracy Corrector is planning to just use it every turn without exception. The cost effectiveness of spending points or actions on attack mods drops off sharply if you're using it.

Thanks for the reply !!
