When I first learned about the upgrades, I thought the +10 reflex obviously wasn't going to stack with a resist +5 item. I was fully expecting a +5 bump to reflex saves, but this turns out to not be the case.

In fact it stacks with a lot of things. It appears to be untyped.
If Update 10 hits the live servers without being tweaked this will definitely give warforged evasion tanks a good alternative to the other existing docents out there for fights like the eChrono abishai boss.
In all honesty though, it seems like an oversight that the reflex save as an untyped bonus. This really outclasses endgame gear upgrades, where you can spend vast amounts of resources and time into bumping up saves/stats/damage/what have you by 1-3, where as this docent and upgrade only took me 2 days and about 2 runs of the new chain on Lamannia.
Thoughts?
