One thing i did notice in the low level dungeon was the turning rules not working well as writen where you use the monsters Hit points as the DC for turning, The party encountered a undead bug bear with 42 hitpoints, with the rule as currently writen a 20th level cleric is only going to have better than a 50/50 chance of turning it or have I misunderstood the turn effect wrong
You're heading in the right direction. Let's see.......
An INT 16, 20th level cleric will have a Magic Attack of d20+23, meaning they'll need to roll a 19 or 20 to exceed the Undead Bugbear's 42 hit points. Ouch. that might sound like a bug (bear?), but it's not. I did that on purpose.
Y'see, it means that even at high level the cleric is unlikely to be able to use an encounter-ending ability before the other characters get to do anything fun. Picture something like this:
GM: A bugbear lunges toward you. From the stench and the flaying flesh, it's clear it's been long dead, though that's not stopping it reaching out to tear at your limbs
Cleric: I turn it, calling on the name of Fharpelordimmara (rolls dice)
GM: Ok, it's dead. Moving on..........
Other players: Ho hum.
Remember that it's the
current Hit Points of the undead critter that matters, meaning that the other characters get a chance to soften the target up a little (or a lot) before the Cleric delivers a Turning coup de grace on the beastie when it's Hit Points are low enough. Get that Undead Bugbear down to 10hp and the Cleric can make it explode, which is both cool and messy at the same time. It would go something like this:
GM: A bugbear lunges toward you. From the stench and the flaying flesh, it's clear it's been long dead, though that's not stopping it reaching out to tear at your limbs
Fighter: Attack!
Rogue: Get ready, Cleric. We're going in....
Cleric: I hold back, whispering a prayer to my god as I finger my holy symbol
......
BANG!
Much more fun, even at higher levels. See?
Of course, if that doesn't suit your style of play and are of the opinion that 20th level characters should be near gods with the power of immediate arbitrary life or death (I'm not, as it happens), then change is cool too. I suggest setting the DC equal to 10+(hp/10). That should do it.
Hope that helps!
