I haven't gone through all the replies of this thread so I don't know if someone else already addressed this but I have a concern with the elemental ranged touch attack abilities.
I am curious why, when they are already ranged touch attacks, do they require a reflex save for half damage and to negate the effect. I can understand negating the debuff effect but it should probably be a fortitude save for that. And typically if something is an attack roll it does not require a save.
Someone probably already mentioned this but if not I figured it should be brought to your attention :).
Cheers!
EDIT: Okay looking up just a few posts above me Nipin addressed the blast exploits as well. I would like to clarify that I think the staggered/sickened conditions should be fortitude saves and the dazzled condition should be a reflex save.
