Sorry, I am having pronoun trouble. Which rule are you talking about? Are they turning them, or damaging them? Is the [effective turning level +4] a permanent cap? (ie. would a 1st level cleric always be able to effect 5HD undead?)
The damaging rules, sorry I was not clear about that.
I put down two ways of limiting what HD of undead could be damaged, so if one was to use [Effective Turning Level +4] then the only thing that makes a cleric able to turn an undead of a greater HD is by being a higher level cleric, this rule is not unlike the core rules in that a cleric if lucky can make a "Turn Check" affecting undead of the cleric's level +4 (not counting any feats).
No, a cleric would not always be able to effect 5HD undead, if for example one used the rules that I outlined on how TR can help undead out in this respect, not only on Resistance, but also as a bonus to HD, examples above.
I did not state before but also under these rules an evil cleric could use the [Effective Turning Level +4] (not counting feats) or [Effective Turning Level +1/2 Cha. Mod.] for "Bolstering Undead" so that the cleric can make the undead even more hard if not impossible to "Damage" although there should be a form of "Damaging Vs. Bostering" so that one or the other would have a chance of overcoming what the other is doing.
Bolstering Undead Examples:
Ghoul 2HD +2 TR Bolsterd by 1st-level Cleric, would make the ghoul treated as a 9HD undead only to see if the cleric can hurt the undead in the first place; So a cleric that wanted to be able to "Damage" this ghoul would have to have an [Effective Turning Level 5] if the rule [ETL+4] is used if [ETL+1/2 Cha. Mod.] is used then it would be taken case by case.
One could also rule that the 1st-level cleric that is unable to "Damage" the ghoul this round may be able to do so in the next round if the evil cleric no longer bolsters the undead.
The way to handle this is by subtracting the [ELT+4] of the "Damaging" cleric from the [ELT+4] of the "Bolstering" cleric.
Example:
The 1st-level cleric should be able to "Damage" an unbolstered ghoul, but as the cleric tries to do so vs. a 1st-level evil clerics bolstered ghoul, it is undamaged, but its "Bolstered" 9HD drops to 4HD, so next round the cleric should be able to "Damage" the undead as normal as long as the evil cleric does not "Bolster" the ghould before then.
This could also work for the [ETL+1/2 Cha. Mod.] just with a few adjustments.
Even under this rule is is possible for a cleric of high enough [ETL] to "Damage" even "Bolstered" undead, or if the [ETL] of the cleric is too low, then it may take more then one "Damaging" attempt before the cleric is even able to "Damage" the undead.
Well I hope that helped, yes a little long winded huh.
