I'm fine with those feats, as long as we add a composite longbow to go with Mounted Archery.
Sure, although Mounted Archery will also apply to its Improved Weapon Throwing I was thinking we'd give him a mighty bow as well.
Speaking of weapons (and armor), should we make any of it magic or at least masterwork?
I was presuming he'd have gear worth the standard treasure value of a 13th level NPC - i.e. 35,000 gp.
OK, skills that are ranger, paladin, and blackguard class skills have a max of 16 ranks. However, we only have enough paladin/blackguard ranks available to max out 3 such skills. I propose going with 16 ranks in Concentration, Ride, and either Heal or Handle Animal (probably Heal).
Concentration will come in handy for casting its Blackguard spells and
true strike SLA, so it makes sense to max that out.
It seems funny having an Undead with the Heal skill, but it's rules-legal to use
Heal on an
Undead, plus it'll have learned most of the Heal ranks while still alive.
That said, he'd have uses for Handle Animal too, for training various hunting and riding beasts. If we give it 5+ ranks that also grants a +2 bonus to Wild Empathy, for a total bonus of +10.
We could max out Concentration and Ride and split the remaining points evenly, for 8 ranks in Handle Animal and Heal.
Then we still have 20 ranger ranks left (max 5 per skill). I think I would put 5 ranks each in Listen and Spot, 3 in Use Rope, 3 in Survival, and 4 cross-class in Know (arcana) (for a bonus of +2).
Hold on, he needs 5 ranks in Hide and 2 in Knowledge (religion) as prerequisites for being a Blackguard.
We'd better take the Know (religion) out of its Paladin budget (cutting Handle Animal & Heal by 1 rank each).
I don't like the cross-class Knowledge (arcana), so I'd use those ranger SPs for Hide.
I'd also rather cut the points in Use Rope and put them in Survival. Methinks it'd be using Survival to track dragons with its ranger training a lot more than it'd be tying knots!
That'd result in:
Paladin/Blackguard/Ranger Ranks (48 SPs): Concentration 16, Knowledge (religion) 2, Handle Animal 7, Heal 7, Ride 16
Ranger Ranks (20 SPs): Hide 5, Listen 5, Spot 5, Survival 5
=>
Total Ranks (68 SPs): Concentration 16, Knowledge (religion) 2, Handle Animal 7, Heal 7, Hide 5, Listen 5, Ride 16, Spot 5, Survival 5
=>
Skills: Concentration +16, Knowledge (religion) +3, Handle Animal +13, Heal +9, Hide +0* (
+6 without armor penalty), Listen +7, Ride +19, Spot +7, Survival +5
Don't forget the +2 to Wild Empathy for the Handle Animal ranks.
The +19 in Ride means our sample Undead Dragon Slayer will always make the DC 20 check to control its mount in battle.
