If I get a level 2 feat from an Adventure Path background, therefore gaining it at level 1 instead of level 2, does the feat use my actual level or the level of the feat for the math in its description. For instance, if I'm level 1 and my level 2 feat deals one damage die per 2 levels I have, would it deal 0 damage or one die of damage? It helps if you cite the example.
Alright, the feat in question is Blasting Beams, available in the Dark Archive and reprinted in the Gatewalkers Player's Guide. The campaign-specific background Dreams of Vengeance grants it, therefore allowing it at level 1, and the lore text states outright that you "nearly burned down the countryside" with this power. Yet as far as I can tell, this power only affects a single creature and doesn't get to do actual damage to creatures until-
*gasp* I forgot about the backlash! If you spam this power too often, it eventually results in you dealing 1d6 per level to all creatures in a 30 foot emanation with a basic Fortitude save (the user automatically takes full damage). And when an area effect describes only the effects on creatures, the GM gets to decide what happens to unattended objects, allowing this feat to technically start a forest fire at level 1!
