Shard O'Glase said:I said average and that's being generous IMO. It is really cool for a concept character around summoning but it really is a small benefit to a specific and crappy line of spells. SM spells only get good for combat(which is what this feat helps at) at really high elvels where the benefits of the feats are fairly minor.
Ridley's Cohort said:What a summoner desperately wants is options to increase spells durations to minutes or even hours. Something like: change spell casting time to 1 hour and increase duration to 1 hour/level at the cost of +1 spell level.
