Most summoners have a close connection to creatures from the farthest reaches of the planes. A few have a primal connection to nature, and their power is tied to primal magic. It is not unusual for these summoners to associate with druids, for like druids, first worlders have a powerful tie to the natural world. Some first worlders are driven half-mad by the strange energies and intelligences that seep into their minds and bodies, though, and these poor souls are prone to lash out at loggers, druids, or innocent passersby without considering whether or not they are threats. A first worlder’s eidolon usually resembles a fey creature or a plant monster, though some are fantastic otherworldly animals with exaggerated features.
A first worlder has the following class features.
Starting at 1st level, a first worlder can cast summon nature’s ally a number of times per day equal to 3 + his Charisma modifier. At levels where a summoner would gain a more powerful summon monster spell as a spell-like ability, he instead gains the equivalent summon nature’s ally spell (at 19th level, he can use summon nature’s ally IX or gate). When a first worlder gains a summon nature’s ally spell as a spell-like ability, he adds it to his class spell list (he must still select it as a spell known if he wants to cast it as an actual spell).
This ability otherwise replaces the summon monster ability of a normal summoner.
Summon nature’s ally IV: unicorn.
Summon nature’s ally VII: nymph.
d6 Hit Die (instead of d10).
