If you cast Arcane Lock twice on a door, would the second spell take effect after the first one is suppressed?
I realise the effects do not stack but if two spells are active on a creature/object and one is suppressed the other is still active.
The way I see it is that if a door has two Arcane Lock spells cast on it, it would take two Knock spells to suppress it for 1 minute.
If a creature tried to pick a lock it would increase the difficulty by +10 (not +20), but would it need to roll twice to pick the lock?
As an alternative spell example, if a creature had Bless cast on it, the benefits would not stack, but both spells are active. If one caster loses concentration the effect of Bless would still be active.
Feel free to use other spell examples/scenarios in your answer, if you need. I am happy with any answers from published materials as well as Unearthed Arcana.
