It may have been this way for a long time, but it has been a long time since I've played an AP. If these are features, so be it, but they seem wonky.

1. The help file for controls shows a syntax that does not take a parameter: cast 'fires of ninauurm'. The reality is you need to designate a weapon, in your inventory, to cast it upon: cast 'fires of ninauurm' sword. If you try to give the item wielded as a parameter, this spell and 'control unholy' cannot find the weapon.
* Change the help file to show the required parameter, or remove the parameter requirement.
** Suggestion: allow these spells to work on wielded weapons if no parameter is given.

2. The help file for 'control unholy blessing' should more clearly state that its purpose is apparently to remove controls from weapons. If this spell does more than that, please include it in the help file.

3. Using a control spell on a weapon within your inventory extends the effect to whatever weapon you are holding. This is a 'workaround' for the problem described in item 1.

4. Related to item 3, the affect is tied to the person, not the weapon whose parameter you entered into the spell. Assuming an AP has access to multiple controls, it may be in their interest to have weapons with different attack types, even if only the mainhand weapon could use a control prog.

5. 'Flames of ninauurm' appears in the affect list with a spell timer on it, however when the affect has expired all unholy weapons will still have the flaming effect, including the flaming blast prog.
