Trigger The PCs round a corner, open a chest or door, unmask a villain, or draw back a particularly plush curtain
Requirements The PCs are not thinking about centaurs
Effect A nonsequitaur appears whenever it is least expected. A nonsequitaur comes into being and everyone rolls initiative.
AC 20; Fort +8, Ref +9, Will +9
HP 40
At Least That's Over
Trigger The nonsequitaur is reduced to 0 Hit Points
Effect It isn't, not yet. The nonsequitaur uses MORE! CENTAURS! as a reaction, then dies.
Forget about Me?
Trigger The nonsequitaur leaves the field of view of all of the PCs
Effect The nonsequitaur feels ignored. It uses MORE! CENTAURS! as a reaction.
You Should Have Paid Attention to the Centaur
Trigger A creature ends its turn without attacking, casting spells at, using skills on, or otherwise acknowledging the nonsequitaur
Effect The nonsequitaur dominates all forms of interaction. It uses MORE! CENTAURS! as a reaction.
Speed 40 feet
Melee Hoof +9 (agile), Damage 1d10+4 bludgeoning
Melee Spear +11, Damage 1d4+6 piercing
Melee Spear +9 (thrown 20), Damage 1d6+4 piercing
MORE! CENTAURS!
The nonsequitaur decides that this could be improved by more centaurs. It causes another nonsequitaur to spontaneously come into being in an unoccupied space within 60 feet.
Before you ask, YES this summoned nonsequitaur can use MORE! CENTAURS! as well, NO this is not a design oversight. I write the blog, them's the breaks.
