Does Icathian Rain create Reflexive Triggers that can each be individually reacted to?

Ruling: Yes, Icathian Rain creates reflexive triggers that are added to the chain, and each individual trigger can be responded to before it resolves.

Sequence:

• You can respond to the spell itself before any triggers go onto the chain
• When the spell resolves, all 6 reflexive triggers are added to the chain at once (targets are declared at this time)
• You can respond after each individual trigger resolves, starting with the Kai'sa player (or whoever played the spell)

Nuances:

• The reflexive triggers are not spells themselves
• All 6 targets are declared at once when adding the triggers to the chain, not individually for each trigger
