How can I better utilize Shield as a spell effect? [3 Part Question]

[Volrtaw]

 

I found this post but then couldnt find the bug in the bug tracker. 

 

I've been trying to design a shield spell that scales along with the players statistics, however that doesnt seem to work at all and it only takes flat damage and adds it to HP. I also was trying to "stack" the spell effect--which seems impossible. The extent of what I tried was changing around the damage type and scaling value. I also noticed that added effects on spells seem to disable any HoT or DoT. Perhaps this is just with shield. I feel very limited with it, without it scaling its something id have to make numerous different spells for to allow for perceived scaling. That would break the theme of other spells and I dont want to go that route.

 

I may just use HOT effect in place of Shield effect. 

 

If anyone has any insight on the current state of "Shield" as a "Spell Effect" please let me know!

-Can a spell be recasted and the shield effect continuously added?

-Can spells with shield also utilize DOT or HOT?

-Can Shield spell effect scale?
