Curse Skills Note: Currently, all curse skills seem to be ineffective against chars and monsters. Avoid all curse skills until future updates.

Weaken
Description: Reduces opponents damage and hit rate(?) for a set amount of time. Similar to an ATK buff. Cancels out ATK buffs, theoretically.
Requirements: Level 25, I think.
Required for: None known.

Holy Prison
Description: Prevents an enemy's movement for a set amount of time.
Requirements: Level 40.
Required for: None known.

Notes: At level 1, it lasts, supposedly, for 1 second. At level 10, it should last for 10 seconds. Even at max level, the length of time the curse is active is simply too small to be of much use.

Holy Silence
Description: Seals enemy skills for a set amount of time.
Requirements: Level 45.
Required for: None known.

Notes: Ineffective currently. When made usable, this would mainly be a skill for PVP/PK. Extremely useful in that context, lasting 40 seconds at level 1. Useless otherwise.
