Magma spray...since it is a spray it should be a group affecting spell.
This is gameplay, so I won't flame you, but just...stop posting. Please. This forum is for actual ideas and suggestions, not the first random, half-formed thought to come spilling out of your head onto the keys. That is by far one of the most uninformed things I've ever read -- and I have read a book by Bill O'Reilly.
Anyways, moving to the actual discussion: just remove the cling affect and instead have magma spray have two reflex saving throws. One to avoid the cling which doubles damage, and two (a harder save to make) to only take 1/2 damage.
This way, no DOT, but warlocks can enjoy multiple cling damage (x2 damage) on a single target if they don't carry adequate reflex. Thus, you make reflex more valuable AND at the same time, make mspray deal back its original damage.
