Splash N chooses a TARGET Unit, usually a Foe. Then the AI Selects up to N Units Adjacent to the TARGET (not including itself) at random and repeats an Effect to each of them.
The Effect Syntax is:
Splash N Unit [ Effect ]
The Effect clause defaults to Damage 1 when omitted.
A Unit may only be Splashed once. If N meets or exceeds the number of valid units, then all Adjacent Units are guaranteed to receive the Effect.
