So, the PF Druid can summon a
Cyclops with
Summon Nature's Ally V . The most interesting ability they possess is this one:
Flash of Insight (Su) Once per day as an immediate action, a cyclops can peer into an occluded visual spectrum of possible futures, gaining insight that allows it to select the exact result of one die roll before the roll is made. This effect can alter an action taken by the cyclops only, and cannot be applied to the rolls of others.
So naturally, this begs a question: How can you best make use of this? The most obvious stunt is to make a cyclops charge with a greataxe and declare an automatic 20 for a crit if they make their confirmation roll. If you have a Cleric with the
Destruction domain (or you have the domain as your own Nature Bond through some archetype, probably
Nature Priest), you can skip the confirmation roll, at which point you might as well hand them an X4 multiplier weapon since a 20 auto-hits and the aura auto-confirms the crit too. As a a matter of fact if your character has the animal or plant domain and the ability to spontaneously cast cure or inflict spells, they can just take the
Spontaneous Nature's Ally feat and cast SNA spontaneously as a Druid does.
Anyway, this brings us to a more interesting point. Summons, of course, are a lot more fun if you hand them items that allow them to do unusual things. And it just so happens that Flash of Insight can affect
any type of die roll, not just d20s, so if, for instance, you hand a Cyclops a
Rod of Wonder, you can just have your cyclops pick the effect of your choice. And if you just hand your cyclops a +1
heart-piercing arrow (only costs 1/50th because it's priced as ammunition) with a longbow you can have it auto-kill an enemy without a roll by making it a 20. Another interesting note is that if you give your cyclops a
Ring of Spell Storing, you can store a
Reincarnate spell into it, have your Cyclops cast it on someone and have it pick what form they will reincarnate into, but unless you have a way to increase the duration of SNA to minutes/level (
Hunters get minutes/level SNA when their animal companions are dead, but only for animals that they summon), your Cyclops probably won't have enough time to use it. A Druid can use
Summon Flight of Eagles or
Summon Totem Creature with
Alter Summoned Monster to obtain summons with a 10 minutes/lvl duration, though. For primarily non-combat summons,
Aquatic Cavalry with Alter Summoned Monster works also.
So, really, I'm hoping for any ideas and suggestions on what kinds of mundane items, magic items, and spells (presumably with randomized effects) you can take advantage of using the Flash of Insight ability of the cyclops.
