Planar Wild Shape and Smite Evil

Question

A good druid takes the Planar Wild Shape feat and adds the celestial template to the creature.

Reading the rebuild rules:

• gains darkvision 60 ft.
• gains DR and energy resistance as noted on the table

The table refers to HD. Should I consider the HD of the druid or the creature he wild shaped in?

• SR gains SR equal to new CR +5
• smite evil 1/day as a swift action (adds Cha bonus to attack rolls and damage bonus equal to HD against evil foes; smite persists until the target is dead or the celestial Creature rests)

Should I take the charisma bonus (and HD) of the creature or the druid?

EDIT: In other words

1. The druid polymorphs and then applies the template (in this case the template is applied to the druid) or
2. The druid polymorphs in a 'celestial animal' (in this case the template is applied on the creature).

Answer 1

In all cases the answer is of the druid, because those attributes (Cha, HD) are not altered by wild shape. I think you may be missing the profoundly different way polymorphs work in Pathfinder.

The druid's wild shape ability works like the beast shape spell. And the beast shape spell is a polymorph effect. Read polymorph carefully.

While these spells make you appear to be the creature, granting you a +20 bonus on Disguise skill checks, they do not grant you all of the abilities and powers of the creature.

You do not get the creature's HD or Charisma at all. You get physical attribute bonuses and natural armor based on size, get the creature's movement type and natural attacks (based on your BAB and STR), and specifically listed abilities. This is a significant departure from other editions. You barely need the original creature's stats at all to wild shape - you need its size, number and type of attacks, movement type, and some special abilites (trip, rake, blindsight, etc.) and that is it.

I don't know that "ordering" is the right way of thinking about it - when you turn into the animal, your HD is your HD, not the animal's HD. Whether you think about it as "order" or think about it as "the animal's HD just changed to mine," in either case you'd use your druid's attributes on the lookup table and calculations.
