Hi can anybody point me to a RAW definition of what constatutes higher ground. Also our group is having a debate weather flanking and higher ground stack. Any rulings on this.
It does stack. Untyped bonuses stack, unless they are from the same source.
As for how much higher you have to be for it to be higher ground, that is a GM call, and there are no rules for it.
As far as I'm aware, higher ground is mentioned twice within the PRD; once on a table with various other combat modifiers, such as being dazzled, entangled, or prone, and once a bit later on while referencing riding a mount that is larger than your target. There doesn't seem to be an official definition of "higher ground" in the CRB, or at least not in the glossary. It shouldn't be too difficult to adjudicate though; if you are higher up on a slope or are standing on a table or the like, you are attacking from an elevated position (or most certainly when riding a mount larger than your target). All of the modifiers on the table appear to be untyped, so they should stack when appropriate to use more than one.
The certainly stack because they are two different bonuses from two different sources. I use the rule from 2nd Edition and it seems to work fine:
From Combat and Tactics page 31
Higher Ground
If the attacker's waist is higher than his opponent's head, he gains a +1 bonus to his attack rolls. Stairways, tabletops, and steep slopes may create higher-ground opportunities for a character in combat. This doesn't apply to colossal creatures such as giants who are fighting on level ground against much shorter characters, nor does it apply to mounted characters; they already get a bonus.
It would have been nice if this was explained in later editions.
I should mention that 2nd Edition didn't use the same size categories as later editions. The Higher Ground bonus is written as if the creatures are the same size category.
Its gm call its not away good to have the higher ground but in most cases its a benefit,do we give large best the benefit?
Being large does not count as higher ground. The creature has to standing on a higher point of elevation such as a table or a just be elevated higher due to terrain.
So how much higher is "too high" to attack or be attacked by the lower creature?
So how much higher is "too high" to attack or be attacked by the lower creature?
When person A can not reach person B they can't be attacked. Higher or lower ground is not a factor.
