Some do some don't, but the best part, you can re-imbue the same weapon with different types or undo it entirely, all without making it lose the +10. If you have the ores, just select the different types before applying it, should show you how the scaling changes. Nothing is permanent as long as you have the different ores.
They seems to keep most scaling(except enchanted) but have a reduced base physical damage. Scaling seems toned down a bit, so that base damage is more than it seems. --- DA pawns: low level sorc->psn:EveryGlenn17|200mage->psn:Skallagrimm17|148ranger->psn:Warning17
