I have theory crafted a Rain of Arrows champion trapper, the build has good defence while maintaining good damage, the build is still a work in progress and is not the cheapest build to start, i suspect it could be reliable on a 50 div budget.

The build sits at around 50K armour + 50k evasion without perfect gear, 100% spell suppression and ailment immunity while have good movement speed due to onslaught, adenaline and quicksilver.

The single target dps is around 16 million at the moment as we are able to front load damage before most bosses.

The POB will show x60 Rain of arrows for bossing dps, the reason for this is, we can have 20 traps down at once the 20 traps are doubled due to the Fatal flourish forbidden jewels, however the additional 20 traps have a multipler of 1.6x as they are the final repeat. This gives us 20+(20x1.6)= 52, we then have the helmet enchant for 15% chance for RoA to have an additional sequence so 52 then has a multiplier of 1.15x leaving us with 52 x 1.15 = 59.8.

I will be working on the POB and adding better gear such as double mana reservation on helmet to allow us to run petrified blood for more defence.

Let me know what you think and if you have any ideas/questions!
