Radiant Bastion
(2 items) Adds 1206 Maximum Health
(3 items) Adds 129 Weapon Damage
(4 items) Adds 1206 Maximum Health
(5 items) Deal 10% of all direct damage done to you back to the attacker, up to 4250 damage.

I mean this set is utterly useless but has great potential if tuned properly to be fun and actually useful set.

The damage return should be between 30% or even 40%

Here is your "math"
Average direct damage done of common skills/abilities/sets against players:


Damage After Mitigation
* Light Attack - 1000-1500 damage
* Heavy Attack - 2500-3000 damage


* Dizzy Swing - anywhere between 4000-7000 damage
* DK Leap - 5000-8000 damage
* BlastBones - 3500-5000 damage
* Sub Assault - 3500-5000 damage
* Crystal Frag - 4000-6000 damage

// Procs //
* Caluurion's Legacy - 4000-5000 damage
* Skoria - 2000-3000 damage
* Selene - 4000-5000 damage
* Velideth - 3000-4000 damage



Now lets take an combo of 1 light attack + SubAssault + Dizzy + proc set (velideth for example) which equals between 11500-17500 damage,
Now if you return 10% of this 11500 - 17500 damage this is equal to 1150 - 1750 damage BEFORE MITIGATIONS, lets assume that the enemy player has 60% mitigation( In CP Scenario)

CONGRATULATIONS you just did between 460-700 damage after you took 11500-17500 damage !!!!!! WHAT OP SET, WHAT A LEGENDARY OUTPUT
SO:
If the damage return is 10% the final damage output would be 460-700 (4% actual return)

If the damage return is 30% the final damage output would be 1380-2100 (12% actual return)
If the damage return is 40% the final damage output would be 1840-2800 (16% actual return)
If the damage return is 50% the final damage output would be 2300-3500 (20% actual return)

If we assume this is NO CP Scenario where the avg player mitigation is around 40% then
If the damage return is 10% the final damage output would be 690-1050 (6% actual return)

If the damage return is 30% the final damage output would be 2070-3150 (18% actual return)
If the damage return is 40% the final damage output would be 2860-4200 (24% actual return)
If the damage return is 50% the final damage output would be 3550-5250 (30% actual return)
