Druid Radiant Servant without giving up a spellcasting level?

[gadren]

Is it possible for a Druid to take the Radiant Servant of _ prestige class without giving up a druid spellcasting level? The two main hurdles are getting the Sun Domain and getting Turn Undead.

Taking levels in other prestige classes first is fine, as long as they progres druid spellcasting.

By what level? Contemplative is the easiest way to get a domain but I seem to recall their earliest entry being 11, barring bloodlines.

Any level, though earlier is better. Contemplative gets the domain but not undead turning.

Sacred Exorcist gives turning and spellcasting progression, though I'm far too lazy to check how easily druids can qualify.

You channel divine power and life energy into a bone from an animal or humanoid, giving it limited power against undead. Once cast, it may be used for two purposes (decided at the time of casting).

Bone of Turning: You or another druid may present the bone in the manner of a holy symbol and use it to turn undead. The effective turning level is equal to your caster level. All normal turning effects apply. For example, if your turning level is twice the Hit Dice of the turned undead, they are destroyed instead of turned. After one turn attempt, the bone talisman loses its power (but you can cast the spell on it again).

Bone Weapon: The bone is treated as a weapon that deals +1d6 damage to undead creatures, similar to but weaker than an undead bane effect. The bone is treated as a simple weapon appropriate to its shape, such as dagger or dart (small and sharp), club (if large and blunt), or spear (if small and sharp and fastened to a haft) and deals normal damage for its type. The spell does not grant proficiency in the weapon. The spell is not discharged when the weapon hits and this aspect of the spell lasts until the full duration (10 minutes/level) expires.

The spell has no effect if you cast it on a bone taken from an undead creature. The bone must be at least 8 inches long and may be straight or curved; normally bones from the arm, leg, or ribs are used. You may carve, drill, or otherwise shape the bone before or after the spell is cast; the spell functions as long as the bone remains bone (not turned to wood or metal, for example).

As for the Sun domain, Catalogs of Enlightment (Planar Handbook) is a decent option, though you need to get K:The Planes early so you can pick it at 6th level.
