There are 3 Arcane Reflection spells: Minor Arcane Reflection (reflects 15 spell levels), Arcane Reflection (reflects 30 spell levels) and Llengrath's Reflection (reflects 50 spell levels).
If a wizard casts all of them, while they are all active and before any spells are reflected, are they able to reflect 50 spell levels (in which case they don't stack) or 50+30+15=95 spell levels (in which case they all stack)?
