Curses

Amplify Damage

Difference from the LoD version
Slightly less physical resistance reduction.
Pros
Still the strongest physical attack supporting skill. Works fine with Corpse Explosion, too.
Cons
Small radius at low slvls. No other effect than physical resistance reduction.

Weaken

Difference from the LoD version
Also reduces target's physical resistance. Can negate a very large part of target's physical damage by synergy.
Pros
Large raduis and long duration at low slvls. Not only very defensive but also works as mini Amplify Damage.
Cons
Can't reduce monster's elemental/magic damage.

Terror

Difference from the LoD version
None.
Pros
The most fast-acting emergency curse.
Cons
Some monsters are immune to AI curses. Doesn't help killing monsters.

Dim Vision

Difference from the LoD version
None.
Pros
Effectively disables ranged attackers and casters. Suppresses many special abilities of monsters (jumping, resurrecting corpse, spawning eggs and children, etc.)
Cons
Some monsters are immune to AI curses. Less offensive than other AI curses.

Confuse

Difference from the LoD version
None.
Pros
Disables ranged attackers and casters to some extent. Enemies may attack each other, so more offensive than Dim Vision.
Cons
Some monsters are immune to AI curses. Confused monsters attack random targets, so your minions and party members may still be attacked, especially when ther are closed to the monsters.
