Since WW oscillates, Ambo’s autocast does oscillate. Edit: Clarified interaction with DW and Ambo’s Pride, which wasn’t specified earlier. It’s very tricky to conclusively test the last interaction I can’t think of a test setup that can do it as of now, since Ambo’s resolve in 1s (a bit too quickly). Rend from selfcast and Rend from Ambo’s have a separate cap (2 each).Rend from selfcast and Rend from Ambo’s share the same cap from Lamentation and “the newest” instance is ignored.Rend from selfcast and Rend from Ambo’s share the same cap from Lamentation and “the newest” instance overrides the “oldest” instance.Untested: It’s unclear right now, if Ambo’s override selfcasted Rend instances. Damage is accumulated and displayed every 48 Frames (0.8 seconds). Rend ticks every 12 Frames (0.2 seconds).This makes Bloodbath by far the best DPS rune (doubling the damage output). Rend:Bloodbath explosions count as a separate Rend instance but are capped at 2 due to Lamentation.Ambo’s pride can’t exceed the Lamentation cap of 2.Ambo’s does oscillate between main and off-hand, since WW does.Ambo’s does apply the equipped rune from the skillbar.Ambo’s has a proc-coefficient of 1 and applies a Rend on each WWs tick.Rend applied by Ambo’s does not proc Area Damage.A Rend instance snapshots CHC upon cast.Battle Rage:Into the Fray does not have a cap, increases CHC in sheet and therefore works with Rend.Battler Rage:Bloodshed has 0 effect on/for Rend damage (except for the base rune crit), because Rend does not crit.Any debuff-CHC (Iceblink, Multishot, Corpse Lance, Bash, etc.) will not scale Rend. Only CHC and CHD that you see in your detail sheet, will scale rend.Each Rend tick has (1 + CHC * CHD) as a separate multiplier.Rend scales with CHC & CHD but CAN NOT crit.WW, and therefore Ambo’s, oscillates between mainhand and off-hand. The off-hand can be any off-rolled weapon for supporting purposes (CDR, AD etc.). Rend’s selfcast damage is only calculated off mainhand.Rend’s base duration is 6 seconds, not 5 (the tooltip is straight up incorrect).Tested everything I could think of to test about rend.
