A situation came up recently where a character had no other option than to draw an attack of opportunity while attempting to gain psionic focus. Fortunately the attack of opportunity failed to find its mark but this led to a discussion as to what happens if a character takes damage while attempting to gain psionic focus. The DC to gain focus is 20.
Examining an example item in the table 'Damaged during the action.2' The footnote 2 begins with the qualifier 'Such as...' This could be interpreted as an example condition but not necessarily limited to that example condition.
Does this mean the DC to gain focus is 20 at a minimum but could be higher for example if 10 + damage dealt is greater than 20? Or does this mean gaining psionic focus is always set at 20 and no additional factor could alter the DC by increasing it?
Which then also raises the question can a character attempt to gain psionic focus defensively? Though no option at least I'm aware of allows for this, it seems to contradict the narrative conception of the action being performed and I guess this would be an entirely separate question in any case.
