Weapon Imbue - Sonic Damage
Elemental Strike/Malestrom - Sonic Damage & daze/stun effect (save for half duration)? - or maybe deafen or silence?
Armour Imbue - Sonic Resist
Greater Armour imbue - Sonic Resist & bonus to listen/spot?
Seems odd that it's the only elemental type missing from the list (postive/divine I assume are restricted to divine casters, and i'm not sure where the new three types sit yet)
while we're here, possibly add magic to Armour imbue and Elemental Strike too?
Greater Armour Imbue - raises abj spell focus by 1 level?
Elemental Strike - 10% chance of breach effect? - 5% with save (would keep it inline with Maelstrom, but toned down)
