Call Woodland Beings

By means of this spell, the caster is able to summon certain woodland creatures to his location. Naturally, this spell works only outdoors, but not necessarily only in wooded areas. The caster begins the incantation and continues uninterrupted until some called creature appears or two turns have elapsed. The verbalization and somatic gesturing are easy, so this is not particularly exhausting to the spellcaster. Only one type of the following sorts of beings can be summoned by the spell, and they come only if they are within the range of the call.
The caster can call three times, for a different type each time. Once a call is successful, no other type can be called without another casting of the spell.
The creature(s) called by the spell are entitled to a saving throw vs. spell (with a -4 penalty) to avoid the summons. Any woodland beings answering the call are favorably disposed to the spellcaster and give whatever aid they are capable of. However, if the caller or members of the caller's party are of evil alignment, the creatures are entitled to another saving throw vs. spell (this time with a +4 bonus) when they come within 10 yards of the caster or another evil character with him. These beings immediately seek to escape if their saving throws are successful. In any event, if the caster requests that the summoned creatures engage in combat on his behalf, they are required to roll a loyalty reaction check based on the caster's Charisma and whatever dealings he has had with them.
This spell works with respect to neutral or good woodland creatures, as determined by the DM. Thus the DM can freely add to or alter the list as he sees fit.
If the caster personally knows a certain individual woodland being, that being can be summoned at double the normal range. If this is done, then no other woodland creatures are affected.
If a percentage chance is given, druids and other nature-based priests add 1% per caster level. These chances can be used if no other campaign information on the area is available.
