The strengthen rune strengthens the object in question. The effect of this rune is to cause a living creature to increase 1 attribute/10 power. Non-living things will gain 1 AP/5 power. Note that if the entire creature is strengthened, then all 6 attributes split the attribute total. The resistance is the total of the attributes affected. Strengthen is not permanent and will cease when the spell is let go.
While his compatriot is in battle, Jeremy the Battle Surgeon (Will of 5) decides that he must help his friend. He decides to cast Strengthen on his freind with a Strengthen Str (Level 4). Using an power of 9 and a range of 1 (2 m) his target number is 6 [10-4]. Gaining 2 successes, he takes 8 MF, and cast the spell with a power of 45. His friend’s Str is 7, therefore he has a resistance of 33. This leaves only 12 Power left. This means that he can only raise his friend’s Str by 1.
This is an Temporal Spell.
