Magic is magic it isnt because it use soul or mana. The energy is magical it isnt the casting cost that he absorb it is the magical damage which including if a weapon does magical damage. So it would still absorb so all reaver element are kinda healer.

Raziel damage is still very low on Magus when he actualy doesnt heal him and even if Magus need to be at about 15 meter to cast his spell. I highly doubt Raziel can make it in time before Magus is gone again to gain distance. From what i read TK ability of Raziel are far from great (unlike Kain) and his main strenght are his elemental reavers (Which are working mostly as healer because of Magus Barrier) Raziel is suposed to be very evasive. Which is something good against melee attack mostly. Magus is very evasive too. Tossing Magus a little here and there wouldnt do damage to Magus. It would just be annoying a little.

Magus could stand still and get a beating and it would still not harm him much. Hell, the strongest Sword in Chrono Trigger (rainbow) is merly more then a scratcher on a critical hit and in here he got an armor even better and wear an helmet that is the strongest in the game to the exeption of ozzy pants that is cursed. Being said that Raziel wouldnt be able to harm Magus and the Zombie would probably not be able to do more then smell bad! There is no way Raziel can win. Magus could also equip a Prism Specs accessories making his physical damage do 50% more damages. (As if he wasnt already strong enought )
