Cloak of Shadows grants the target a dodge bonus of 15 + ( int / 3 ).
Let's say this amounts to 18.
That means that for 4 turns, the target has a 1,8 % (!) chance to dodge attacks. And that costs 10 mana.
The spell description claims a dodge chance of 15 (not a 15 bonus to the dodge stat) so I guess someone slipped a decimal on the effect.
I could see 18 % for maybe 5 mana. But 1,8 % for 10...? That's kind of useless.
