You add the number of temples to your d12 roll.
So if you had 3 temples, you roll d12+3 and compare your result with the attack bar.
ie:
roll 7 on d12 than add 3 = 10 (9-10 = stun)
roll 12 on d12+3=15 (11+daze)
So:
with 3 temples out, you get stun on 7-8 (two results) and daze on 9+ (4 results)
with 6 temples out, you get stun on 3-4 (two results) and daze on 5+ (7 results)
etc.
Temple of Light loses the chance for stun when you get 9-10 temples out (you roll 1 od d12 and add 10 = 11 = daze), but it seams very unlikely situation.
