Armor Class 29 (Shield +3, Robe of Archmagi, Shield Spell, +4 Dex)
The
shield spell only lasts for 1 round, so in order to have it "always on", he's going to have to cast it with his reaction every single round, which means he can't ever use
counterspell (or take any other reaction).
ASIs: Spell Sniper, Stealth, War Caster, Wood Elf Magic
Just FYI: Wood Elf Magic doesn't add
pass without trace to your spells known. It just lets you cast the spell once per day without needing a spell slot. So his Stealth won't be at +26 for more than 1 hour each day (and while it is, he won't be able to benefit from
greater invisibility and
darkness as well, since they all require concentration).
Heightein Catapult (No verbal component): It's amazing on the battlefield, you can simply destroy walls, covers and give high damage from invaders while staying stealth. Fantastic.
Just wondering if you are aware that
catapult's initial range got nerfed to 60 feet. (That is, the object you affect with it has to be within 60 feet of you now.) Also, why bother using Heighten Spell on it if you're using it against walls and other inanimate objects? They don't get saving throws against the spell, only creatures do.
2) This your "archer" is completely useless, there are no covers. Easily found and killed by Undeads.
Why is there no cover? Can this guy only ever be encountered on a featureless plane? Since we're talking about high-level play here, there's nothing stopping the PCs from making their own cover. There are plenty of spells they can cast to stop this guy's minions from getting at them easily.
And detail, it's an Army of Undeads and not 8.
He was referring to the fact that you can't create a massive army of undead using the
animate dead spell due to its built-in limitations. Since this guy is an NPC, then yes, you can give him a whole army of undead, but he wouldn't be able to have all that many if you're adhering strictly to PC rules.
It still has some balors around.
Balors?! You haven't mentioned them before. Where did they come from?
Staff of Warming Insects (No concentration)
This is new. I take it this is to counter
see invisibility and such? All it needs is a strong wind to blow the cloud of insects away. Not something that should be hard for high-level PCs to conjure up.
How are you going to spend at Heightein Sanctuary?
Heighten Spell only affects the first saving throw made against the spell after you cast it. Since we're supposed to be attacking this guy with a whole party, they could just chuck a cantrip at him or something to get rid of the disadvantage.
Dispel is a harmful spell, Sanctuary works normally.
First, I'd just like to point out that
sanctuary is only a 1st level spell, whereas
dispel magic is a 3rd level spell. Take that for what it's worth.
Also, you do not have to target a creature with
dispel magic. You can target a "magical effect" as well. So you could arguably target the magical effect generated by the
sanctuary spell rather than the creature who cast it, thereby bringing down the spell without having to make the saving throw.
That said, even if the DM rules you still have to make the save, as I pointed out above, you can just have someone chuck a cantrip at the bad guy to get rid of the saving throw disadvantage from Heighten Spell, and then chances are pretty good that a high-level party will be able to dispel that
sanctuary.
