Spells with duration increased by int

[Vilk]

The int description mentions that every 15 points spells duration effect is increased by 1, fine but that's not right with all spell. Many keep the same duration.

Is there a list of spells affected by int for their duration? I didn't found this in gamebanshee and was curious to see the list.

Here a partial list (a NOT for those with a duration not affected by int):

Order :

• Battle Cry
• Bless
• Demon Slayer
• Dragon Arrows
• Dragon Slayer
• Peacefulness
• Divine Armor: NOT
• Helplessness: NOT
• Last Hero: NOT

Distortion:

• Haste
• Magic Spring
• Magic Shackles
• Precision
• Shroud
• Slow
• Berserk: NOT
• Blind: NOT
• Invisibility: NOT
• Phantom: NOT
• Pygmy: NOT
• Shadow: NOT
• Stone Skin: NOT
• Target: NOT
• Trap: NOT

Chaos:

• Greasy Mist
• Hell Breath
• Weakness
• Fear: NOT
• Kamikaze: NOT
• Plague: NOT
• Sheep: NOT

The list of spells with duration not affected by int is quite long. A design error when you see the game unbalance of mage vs warrior, weird.
