Hello everybody

I've returned to the series after 4 years and I've already gone through BO1 and SR1. I'm half way through SR2 and something sparked my curiosity. In SR1, SR2 and Defiance the wraith blade can get several elemental enhancements and I know that each gives the blade some properties but I never figured/found out all of them or how they impact the damage done on different foes.

Does anybody have more information on this? I'm quite interested in non-puzzle related properties(dark reaver can blind those stone/metal eyes, light reaver can open doors, air can powerup those air/ventilation platforms, etc). I also know that, in Defiance, each elemental reaver casts a spell when charged.

This is what I know so far
- SR1: fire reaver deals more damage and the projectile can burn the enemies if they are sufficiently low on health
- SR2: air reaver makes Raziel move faster through the muddy water in the swamps; fire reaver also appears to deal more damage

Apart from this, does the dark reaver deal more damage to humans and less to daemons? Does the light reaver do the opposite? Does the air reaver heat up slower than the rest(SR2)? Is there an order of damage dealt by the different reaver enhancements(Defiance)?

As far as I know when it comes to combat there is no difference in basic damage in any of the games (except Spirit Reaver of course).
