Larger missile weapons require several points of this spell to create a single missile, but only manually projected missiles can be affected, no mechanically projected missiles such as ballista bolts or trebuchet rocks. As a rule of thumb, each 2d6 or fraction of weapon damage requires one point of spell. The temporal nature of this spell means that it can be cast onto a missile and the spell will work once only if the missile is used during the spell's duration. Stormblade by Gavin McIntyre 4 points,Touch,Temporal, Passive When cast on a blade the edge shows a a faint blue fire running up and down and there is a smell of ozone eminating from the blade. The spell increases the damage by 2D4 but the extra damage ignores all metal armour.
Magical defenses work normally.
On a fumble, if the weilder hits themselves, the additional damage is dealt normally. The weapon affected by this spell will always deal maximum normal weapon damage on a successful attack. If the attack is a special, any additional damage is rolled for as normal, rather than being maximum. A critical success is as normal. The spell damages the very air that it passes through, making a low rumbling noise when swung.
