Casting?

[CaPtMalHammer]

Just an idea but not sure its possible? Is there a list of spells out there that persist from round to round so multiple spells can be active at the same time without concentration checks for each? Example: tentacles that attack, a rolling ball of fire that moves around, a floating sword that attacks and an illusionary warrior that attacks all active and moving at the same time? I know this will take rounds to cast each of the spells but once cast you could have 5 or 6 spells active at the same time.

As long as the spells do not explicitly require concentration (i.e. a standard action each round) you can have as many spells active as you can cast, if all their durations overlap. there aren't that many that actually require concentration.

Sure.

Evard's black tentacles + forcecage + deeper darkness + summon monster IX (elder water elemental - vortex form) + persistent image of a giant sea monster is pretty cool.
