I recently stumbled upon an interesting combination:
Magical Lineage+Holy Ice Weapon+Furious Spell.
Does that mean that the weapon that is generated with the spell gets a +4 to its damage on every attack?
The text of Furious Spell indicates it requires an attack spell, so I'm not sure about RAW.
Any insight would be welcome.
I'm not sure it works at all with Holy Ice Weapon, because conceptually the sword is dealing damage, not the spell per se. But then the spell is providing nonstandard damage to the sword, so maybe.
But even if it works at all, I think it's clearly intended to only work once for continuous damage based on this:
Spells that affect multiple targets deal the extra damage once to each target, regardless of whether the spell deals its damage all at once or in multiple hits (in the latter case, add the extra damage to the first hit against each target).
