I want to ask a question on the main site. This is the current draft:
How does Time Stop interact with the duration of other spells?
You briefly stop the flow of time for everyone but yourself. No time passes for other creatures, while you take 1d4 + 1 turns in a row
I am having trouble determining how this is supposed to affect the duration of other spell effects. That is, whether these extra turns taken by the Archmage count towards the duration of spell effects that were already present at the time of casting.
I am assuming (possibly wrongly) that the answer depends on the nature of the spell/effect. The main point that I want to know is what factors, if any, are used to determine wether a spell duration is affected. I have considered this (non-exhaustive) list of factors:
- Whether the spell affects only the Archmage, only other creatures, both or no creatures at all.
- Whether the spell was cast by the Archmage or someone else
- Whether the spell is a concentration spell
- Combinations of these factors
Specific spells that I am concerned about (since they may come up during the encounter) include:
- The Archmage's self casted Mirror Image, Globe of Invulnerability
- The Archmage's Banishment cast on an opponent
- PC's Blindness/Deafness, Compelled Duel cast on the Archmage or an Archmage's ally
- PC's Bless only on PCs
So which factors are used to determine whether the extra turns one takes during Time Stop affect a particular spell?
This, to me, screams "too broad" for having way too many things to consider. It may also attract valid answers that simply say "this what happens with this spell or in this case in particular" which is not what I want.
On the other hand asking individual questions on the interaction of each of these spells with Time Stop seems excessive.
How should I solve this?
