After reading a few posts I was interested in what ritual effects all together and if the qeynos claymore reward has the same effect and this is what i came up with.
This is just the items in which i was comparing the effects of ritual and the claymore proc to.
This is what the qeynos claymore and ritual produced. They were identical in the fact they increased the power return of procs, manastone effects, and raw power effects like heart, shard, and pantrilla.
I also wanted to see if there was a cap to how much it would return so I pumped AA's into ritual and took 4 common items and compared them below.
So ritual does have a decent use but in a raid my qeynos claymore procs alot as does some of the items i wear. The skullcap of the dark master has given me about 1000 power back off a group heal.
I hope this is at least useful to anyone thats debating on there AA setup and I know razieh is specced into rank 1 of ritual, so he could probably explain why he wanted to spec that way.
Also i found that ritual and the claymore does not effect symmetry, healing pulse, or plus to healing effects (restorative clasp) but does effect the heal from leggings of corruption.
