I think there should be some possible tweaks to Pale Master when looking at what is available to arcanes already in general.
Pale master prestige increases damage for negative energy spells, and crit chance for negative energy spells per tier, up to 9%, but does not increase crit multiplier of those spells. Being that there isn't a negative energy enhancement line like there are elemental enhancement lines, the crit and damage to negative energy spells had to be added to the prestige. The values should be adjusted accordingly with the elemental enhancement lines since the focus on negative energy is the main point of the prestige. Currently right now:
1. Elemental damage enhancement lines go up to 40% damage (pre giving 45%)
2. Elemental crit change enhancement lines go up to 9% (pre giving 9% so on target there)
3. Elemental crit damage enhancement lines go up to 2.25 multiplier (pre only giving 1.5)
After Update 9:
1. Elemental damage enhancement lines go up to 50% damage (pre giving 45% and should be adjusted accordingly since negative is your main focus)
2. Elemental crit change enhancement lines go up to 9% (pre giving 9% so that's ok there)
3. Elemental crit damage enhancement lines go up to 2.25 multiplier (pre only giving 1.5, no change in update but should still be brought in line to 2.25 multiplier)
Also with update Savants are getting spell like abilities for their prestiges just like Pale Master and Archmage have with theirs. However, a concern I have is that Eladrin stated that metamagics will be applying to the Savant spell like abilities (and they do, I've tested them), but:
1. Metamagics do not apply to Pale Master spell like abilities. I'm not sure if it's just Maximize and Empower that don't apply, or all of them do not apply. Since it lists no save on the abilities, but mobs seem to save an awful lot on them, I would assume Heighten doesn't apply either (they save near constantly in amrath or content of similar level against the SLAs but do not on my Wail with a 43 Necro DC).
2. Metamagics do not apply to Archmage arcane bolt (different prestige, but still same issue). I know for sure that Heighten, Empower, and Maximize do not apply, and would also assume Quicken doesn't as well (obviously can't be interrupted, but still casting speed makes a difference).
Another tweak I think could be made is to the Pale Master ToD set. Let's face it, it's kinda sucks. The set grants a +30% damage bonus to all level 9 and under negative energy spells, and +60% bonus for tier 3. Being that the highest level negative energy damage spell is level 6, any superior potency 6 item will work on any and all of them (if a sorc chooses to get necrotic ray or negative energy burst for some reason, he gets same bonus). So really you're only getting +10% damage for a two piece set for having the prestige.
I think the set bonus should be tweaked to be of more use to Pale Masters (currently use Rahkir's since it's more useful with only the first bonus than my actual prestige set bonus is, and there is a problem with that). It should at least get Major or Superior lore for negative energy spells in addition to the potency on it imo to make me want to use it over another prestige set.
Basically just looking to:
1. Have the crit chance/damage be on par with the elemental lines since it is part of the prestige.
2. Have the SLAs of Pale Master and Archmage allow use of the metas like the Savant prestige SLAs do
3. Tweak the ToD set so it's actually worthwhile to a Pale Master. After all we should be using our own set, not another prestige set because their's is better at tier 1 than even our own at tier 2.
Anyway, just random thoughts on a prestige I think needs to be tweaked a bit to give it the same bonuses and benefits other prestiges are currently getting. Honestly don't think it's asking for too much either. A ton of /notsigned to be followed I'm sure.
