The reworked Ralakesh's Impatience boots make your minimum charges equal to your maximum charges when standing still. This got me thinking about the possibility of a charge stacker who only needs the stacks while standing still, for example when casting a spell.

These boots should also interact in an interesting way with another unique, Malachais loop. This shield normaly removes all power charges upon reaching the maximum. However, this is not possible when your minimum charges is equal to your maximum, therefore the downside of this unique is completely bypassed! in return we get 2 extra power charges and a whole lot of increased spell damage. void battery is a good choice for a wand as it stacks heavily with power charges and grants another. in the end as an occultist we can end up with an easy 10 power charges! with more possible after some heavy investment.

Another fun interaction from ralakesh's impatience is with Inner Conviction. Inner conviction normally makes you unable to gain frenzy charges, but since we work with minimum charges this is not the case. This way we can benefit from inner conviction while also using Badge of the brotherhood to grant ourselves 10 frenzy charges for a total of 70% more damage! (30% from inner conviction and 40% from frenzy charges)

I have built up a quick POB which is by no means optimal but should give an idea POB. No doubt a more experienced player can make something better out of this.

All in all to me this seems very promising. My only worry is how long it takes for ralakesh's impatience to trigger and what happens if we cast, move while the projectile has not hit an enemy yet, i think the damage should snapshot from the moment we cast and is therefore affected by all of the charges.
