Hello everyone,
I think we are presented with an unique opportunity to better analyze reaper damage boosts and reduction "thanks" to a funny bug. If you have the primal avatar "Reborn in Fire" T2 ability and equip the Lantern Ring, you proc the ring light damage on yourself and allies. (Also, the Epic Strike applies the damage to some allies as well, but not all of them apparently).
The damage is scaled by reaper amplification, in fact on elite you oly get ~50 dmg, while on reaper far more. Here's an example:
(Combat): You suffer a total of 1,043 points of damage from 3d6 Light Damage on harmful spells cast after 15 were blocked by energy resistance.
yup, I killed myself with this
The good thing about this is that we know basically every stat about ourselves (spell power, resistances, absorption, MRR, etc).
I had 700 spell power, 70 MRR, 15% absorption so taking into consideration this, the dmg is 260 compared to the base 3d6 on R8 (so we could roughly assume a 22 multiplication of damage).
As long as this bug is available, I'll gather additional data stepping into different difficulties, also since it has friendly fire as well, we can have an estimate to dmg reduction as well.
But if you have time to spare and get additional data, we will get better estimates
