Hyperfocus


Rules Discussion


So I am playing a Prince of the Moon Cloistered Cleric and have the delerium domain.

The focus spell for that is the pretty cool Hyperfocus,

So they way it works is that if the target fails there save then they cannot perceive anything beyond a range of 20 feet with any of their senses.

This rather conveniently also effect stuff like tremor sense and scent which are also senses and this also seems to get around true seeing as its a divination spell rather than transmutation and illusion.

So I was wondering how this would play out in play.

If you are an attacking an enemy under this effect and are 30ft and had moved whilst it was under this effect I think you would count either as or hidden/ undetected ? to the creature (as it can't sense you at all) and if you attacked that enemy it would be flat-footed to all your attacks whilst outside its ability to perceive.

If it tried to attack you it would have no way to pinpoint what square you are in (no senses) so I am assuming at least 50% miss chance (possibly a random square guessing game ?).

Obviously it can still move in the general direction of where the damage is coming from and attack your melees allies who are within 20ft without any problem.

Have I got the spell correct ?


Yup, undetected. God I love the senses and perception rules, so simple when learnt.

The target can also move towards where they think you should be, although many should likely seek for you (with no effect
) at least once.


You should be Undetected (not merely hidden since he doesnt know your exact location) by the creature yes.

But as soon as you are within the 20ft you are instantly visible to him.

Now, perceiving the general direction of your attack probably depends on the attack itself, projectiles (mundane and magic) should probably give it away, while stuff like Mental attacks probably not.

for attacking you while you are Undetected:

basically it has to guess the square you are and roll a flat dc11 check if it picks correct. Also, it's flat-footed vs you.

This is a neat focus spell. It can either be a potentially crippling debuff for an enemy, or a great boon to the right sort of ally. Really anyone who is completely melee oriented and has a special sense, like Scent, but are fighting something you couldn't normally see.

An invisible enemy who isn't constantly sneaking would be immediately detected and observed by hearing alone while your ally is under this spell for instance.

Inflicting it on an enemy makes your ranged characters all Very difficult to attack.

Don't forget that even if the opponent chooses correctly and hits with an attack, they won't know it. They can't perceive anything outside of 20 feet of themselves, so if they tried to strike back with a ranged attack they wouldn't have any clue whether they hit or not. No telltale grunt or any feedback reaches them. Neat all around.


They could ready an action to move toward the source of an attack.
That gives them that much more search area covered by the time their turn rolls around.

Though dang that's strong & reusable. Especially if you can target 4 enemies. Many monsters have the movement speed to likely catch you, but at the cost of how many actions? And NPC types generally won't catch you if you circle around.

I wonder how much encounter/monster design has accounted for spells like this.

Actually, precise hearing means that an invisible enemy can't even sneak without some effect granting them auditory cover or concealment - per the action they immediately become detected if their sneak movement ends without one of those.

Hyperfocus requires a bit of rules legwork, but it's a really versatile spell for messing with enemies. I strongly support learning Reach Spell for it though since 30ft range is cutting it a bit close imo.

well, that's why you pick up Foil senses, and now your sneak works vs hearing, smell, lifesense, and etc^^
