I'm definitely late to the party, but I wanted to update this.
In today's EQ, it's totally possible to solo. Given our healing, you can even pull it off without a merc. Although, I'd recommend keeping a tank merc around for a long time, since they have such incredible damage output.
Spells to Solo By: Not comprehensive. I'm still learning. But the basics are there.
--Ward of Rebuke (periodic BIG damage shield, self only, short duration. Only run it if you're NOT running a merc. ).
--Unswerving Hammer (free dps. Cheap. Fast.)
--Yaulp 5 or better (DIRT cheap. Fast. Increase attack speed. Increase mana regen: Does NOT stack with Blessed Armor line--Yaulp recovers more than the Blessed Armor line).
--HP type One and Shielding buff of choice. Aegolism line rolls them into one. Not sure how Symbols play into it. I think they replace HPT1. So just find the highest levelled one you can cast.
--Blessing of ____ (Cast speed increase).
--Hammer of Judgement or better. (Summoned Weapon. 14/18. Frequently procs decent damage, even vs. non-undead. Of course, you get better weapon damage against undead).
--Vie-line (Creates a resevoir of fake hitpoints, and a percentage of damage taken will come off those first until the resevoir is depleted. Aura of Zealot has the same effect with no limit on the resevoir, but absorbs substantially less according to lucy. Ex: Lucy says panoply of vie is 10% reduction until 2080 is prevened. Aura of the Zealot is 1% until the aura fades).
Since summoned hammers are pretty sweet, don't forget to equip a shield. You can, after all, bash. On a short cooldown. And it can do some surprising damage as it skills up. I'd still recommend hunting predominantly undead, so you get your weapon's Bane damage. I have a spell list called "Combat Prep" which includes summon food/water/weapon, aegolism type, blessing of whatever and miscellaneous stuff like gate. Then I have the "Battle Cleric" spell set with a HOT, average and complete heal, yaulp, ward, unswerving hammer, Vie and a few extra spaces to tailor to the things I'm fighting. The targetted heal shield and reverse ds (unless I'm in the hole fighting gargs--too resistant). Undead DOT, root if they're runners. etc.
Don't forget to grab distillates of Skinspikes and distillates of clarity. I think you can skip alacrity, as the haste wouldn't stack with Yaulp and between having a weapon on an 18 delay, yaulp and a haste belt from the baz, you should be sitting just fine on haste while soloing.
Be flexible.
