I'm going to revive this thread. It's been 6 months and Pathfinder 2E Druid still doesn't have Wild Shape Spell Adjustment. While you could work around it (in theory) by doing numerous temporary adjustments to achieve the same effect there are two problems with that. That is suboptimal, especially with some of my less savy players. But the bigger problem is that all the necessary adjustments don't exist.
Just the base information from Animal Form:
http://2e.aonprd.com/Spells.aspx?ID=10
- AC = 16 + your level. Ignore your armor's check penalty and Speed reduction.
- 5 temporary Hit Points.
- Low-light vision and imprecise scent 30 feet.
- One or more unarmed melee attacks specific to the battle form you choose, which are the only attacks you can use. You're trained with them. Your attack modifier is +9, and your damage bonus is +1. These attacks are Strength based (for the purpose of the enfeebled condition, for example). If your unarmed attack bonus is higher, you can use it instead.
- Athletics modifier of +9, unless your own modifier is higher.
Let's take these in order:
- AC = 16+ your level. Ignore your armor's check penalty and Speed reduction.
----- Closest I could find was AC Modification, but that first requires the player to calculate what the AC should be (not hard) and compare to current... but doesn't take into account the second part. So when casting Wild Shape you'd have to unequip armor in HLO, then activate this adjustment.
- 5 temporary Hit Points
----- Closest I could find was Hit Points which just changes your maximum. Not entirely accurate, but guess it works.
- Low-light vision and imprecise scent 30 feet
----- Requires 2 Temporary Added Abilities (Low-Light Vision, Scent). These don't show up on the Play tab, therefore have to navigate to a different tab to activate.
- Athletics modifier of +9, unless your own modifier is higher.
----- I couldn't find and adjustment for this at all. There is one to give you more Skill Training Increases and one to change the ability score used by a skill. But there isn't one to change the final value of a skill.
Then there are the specific forms:
Generally these are speed changes/additions and natural attacks. I cannot find any adjustments (temporary, permanent or ability) to add natural attacks of any kind (claw, jaw, horn, etc). You can create a Custom Weapon, but then there is no way to turn it on/off and the Customize Strike won't allow me to alter it so it incorrectly thinks I'm not trained in this new custom weapon making the attack bonus significantly lower than other weapons. There is no adjustment for Speed to adjust it up/down per the form.
TL;DR - There isn't a Spell Adjustment for Wild Shape and there are a number of missing adjustments necessary to work around that problem. It is impossible to play a Wild Shaping druid with HLO in the current state.
