Solo cleric options 22-50 on green

[Cen]

Been solo cleric since the beginning due to the massive cleric population and like 3-4 LFG in every popular group spot. Swish has a nice suggestion guide for solo clerics with kunark stuff but im having trouble filling gaps. Im doing scarecrows which was awesome but greening out. Still too low to tackle rather mts giant skelies. Any good undead solo for 22-27 / to 50?

I know the per level guide has a little bit of undead gaps that someone may have an idea for
