This feat has been noticed before, but largely ignored.
Magic Device Attunement
Prerequisite Use Magic Device 1 ranks
If you successfully activate an item with the Use Magic Device skill, you can take a free action to attune yourself to the item. For the next 24 hours, you can activate that item without making further Use Magic Device checks. You can attune yourself to only one item at a time. If you attune yourself to a second item, the previous attunement ends.
Warlock Info guide says Warlocks don't need it.
2 threads at BG vaguely discuss, with my-old-school weenie filter triggers.
http://brilliantgameologists.com/boards/index.php?topic=993http://brilliantgameologists.com/boards/index.php?topic=12205Version 1 --- you do it once, you get a free pass. No big deal, let's move on.
Version 2 ... what happens to the UMD check # itself? Is that the number that's carried forward (so to speak)? In which case, it's possibly near T.O.-ish. If the check # is not carried forward, you're back to Version 1 with an uncomfortably large handwave necessary for whatever it does, to work.
** For purposes of this thread, I'm going with Version 2 = the check number is carried forward.
So there's 2 separate questions :
1) ... what to use it for, like The Word
Caster Level substitute is obvious, as is Augmentation.
Linked metapsi + PsyChiurgery + exp is a river = abusive fun.
2) ... how to get that 1/day spike number, when that sort of thing has never been Opt before (except Omni or Nanobots)
iirc the UMD build record was around 230 ; provided someone has a copy saved from multiple board-pocalypses.
The casually easy focused UMD number is : Take 10 + 23 ranks + 13 stat mod + 23 item familiar + 15 bard 1 spell + 20 cleric 2 spell = 107
Both of these are not 1/day spikes, rather more often usable consistent numbers.
Any ideas for the build, and for using it
