For my level 10 gestalt game I've decided to make something nice for my neutral Dirge Bard/Cleric whose been the only character there for all 10 sessions so far; running amped up Slumbering Tsar so lots of death. It is going to be a lost relic of sorts in the hands of a lich with an army of undead to start, but should fall into the players if things go right for the party in the next couple sessions.
I'm less concerned with text clarity (though point out anything that obviously doesn't make sense) than with general thoughts on power. As it is gestalt things are already a bit ridiculous at times and the character is walking around with something like 3 bloody skeleton giants, an undead hydra, 2 bloody skeleton archers, an undead chimera, and two zombie bat swarms, but I'm wondering with all that in mind if this is going to be the one thing I really regret. It's easy to go overboard when making high-powered customized items, so I was looking for some outside perspective.
• Unholy, Conductive Heavy Mace.
• Counts as a holy symbol for any cleric able to channel negative energy.
• If held by an intelligent undead, the scepter confers +8 channel resistance and immunity versus undead controlling effects. Living wielders are instead harmed by positive energy and healed by negative and receive a +2 bonus on Will saves.
• As a full round action, the wielder may touch the scepter to a mindless undead he controls and store it in an extradimensional space to be called forth at a later time. Alternatively, the wielder may spend a minute and target all mindless undead under his control in a 60ft burst centered on the wielder.
• This extradimensional space seemingly has no limit, but stored undead still count toward the wielder’s HD limit for the number of undead he can control. Any duration for how long the undead remain under his control is suspended while they are in storage. If the wielder gains control of an amount of HD over his limit, the scepter automatically consumes any excess stored undead, starting with the lowest HD creature. Creatures consumed this way are permanently lost.
• As a full round action, the wielder may call forth a single undead creature of any size from the scepter’s extradimensional space. The wielder targets an area within 400 feet and a patch of writhing darkness appears on the ground from which the undead arises. Alternatively, the wielder may spend one minute of concentration to call forth up to 20 stored creatures. For this purpose small and medium undead count as 1, large as 2, huge as 3, gargantuan as 4, colossal as 5, and below small as 1/2. Most swarms count as large.
• By sacrificing some of his own essence or that of another to power the procedure, the wielder may instead call forth any number of stored undead rapidly. As a full round action the wielder and any willing or helpless living sentient creature within 30ft may receive any number of permanent negative levels to call forth the undead at a conversion rate of 5 undead per negative level bestowed, as per the size scale listed above. This ability otherwise functions as the standard calling ability.
