Mapping build to reduce chance of getting RSI?

Several seasons of PoE has left me susceptible to pain in my right wrist when I play for prolonged periods and so I'm looking for a build which has the minimum amount of clicking, but is still capable of completing the Atlas without a big investment.

RF looks to be a good fit but the builds I've seen need several Ex of investment to be able to do red maps. I only have about 120 chaos at this stage of the league, so those builds would be unaffordable to me for a long time (probably all league).

Any thoughts on others I could take a look at, or if a cheaper but effective RF build exists?

Seeing how I had this problem for 12 years, I can highly recommend getting some foot pedals. I use them for movement, where you basically just slam your foot down (holding left click) and then moving the mouse, occationally right clicking (or using keyboard binds).

At 202cm tall and with hyper mobility syndrome, I'm prone to these kinds of issues (along with tendonitis in both wrists, arms etc). It has been sorted...well managed by frequent training and posture correction (arm/wrist problems are many times caused by awful posture, so your muscles on your front becomes shorter and the ones on your back become longer).

Try a cold DoT with foot pedals :)

Also Poet's Pen with either volatile dead + corpse shooting spell or arc+LW. Hold down 1 button (or pedal) and point in the general direction of stuff that needs to die.

Check out wrecker of days builds.
He has a BV RF that was fun and the slomozombiemancer is a blast!
He specifically tries to make awesome fun builds for the disabled and new players.
I love that foot pedal thing, didn't even know about that!
Slomozombies is one of my favorite builds, its cheap and a great league starter!

Good luck!
