Questions about "Area around Caster" effect from SpellMaker

[Dubiousintent]

* How large is the "area"? (If in "game units", how do we compare them to appearances in-game?)

* Is the "area" fixed at the time of casting or is it centered around the caster and able to move with them?

* Are only enemies within the area at the time of casting affected, or are any enemies who enter the area while it's duration is still active also affected?

That one is relatively easy, 4 meters radius (your character is 2 units high, so the unit is about a meter)

I don't think that's how it works (but I could have read things wrong). If you check DaggerfallMissile code above, the effect is only played once (missileReleased trigger condition), and determines who, around the caster, is affected; then if the spell has any effect over time, those targets will be affected over time.
tl;dr: it's a variant of missile, not an aura following you around

It would be awesome to see the damage shield type of spells seen in later games implemented. I think an easy way to do this might be a variation of the mentioned effect duration that can be attached to a spell. With the duration resetting at certain intervals so it would be similar to a pulse effect or a recasting of a damage spell with the enemy given a chance of resist for each click of the duration.

Thank you for the clear answer.

I also like the suggested implementation for "area" spells with duration. "Pulsing" an area spell for each round of duration above one seems like a simple and satisfactory solution to the "aura" question.
