Thanks for the location info.
I tested things with Dark Tactics since i already had it on a character. I edited the 2da for the feat to allow up to 199 uses, and created a quick test item to increment the feat uses. I found that the feat can indeed display up to 99 uses, but anything over that the counter goes blank - I think it is still tracking the number, but nothing displays. So for my purposes, 99 is the highest display limit on feats.
Editing the item 2da seems unable to push the charge counter past even 50.
So 99 on a feat is better than 50 on an item, but only marginally. I suppose I can take the suggestion above and use, say, 2 feats side by side in the quickbar to handle up to 9,999 power points
. Or even a feat for up to 99 and an item for upper numbers.
The drawback to using the feats seem like the clunky Increment and Decrement functions - only changing the step by one at a time instead of a real SET function to set the value. I can see the potential for an instruction overflow if I tried to call Increment 99 times in a row in the same function just to set the value to max.
One thing I noticed about in testing was that when the feat was completely used, to turned gray (which may be a DUH! moment since that's the way it should be), but I was just thinking about how that might be applicable to, say, martial maneuvers. Since # counters don't display on item-granted feats, maybe they also don't gray out when 'used up'. But if they do, it would be cool to see them grayed and thus know they weren't available. I may have to play around with those and see.
(If you can't tell already, I likes me my visual cues)
EDIT:
Tried out setting a warblade move to have a limited number of uses, but the game seems to ignore that all together. I guess not only do feats on items not display counters, they don't even track them. Bummer, but not totally unexpected.
