given that most damageing spells in SR3 have a flexible damage level the hellblast and the fireball became one.
(belive me or not but i actualy dug out my old 2ed books for this)
hmm, wrecker looks to be a sr3 wreck spell set to only affect vehicles so just convert it to that (to learn wreck you have to learn one spell pr type of target, wreck:vehicles, wreck:guns and so on). the above fits for urban renewal to except for the area of effect part given in the urban renewal description...
and ram is a touch range wreck. with wreck you only have to see the target to use it while with ram you have to be in contact with the target physicaly. hmm, would be cool to put your hand one someone wheels and see it crumble to a wreck

(question is, would they attack you or run in fear?)
