strictness of UMD

[theIrkin]

so, i'm playing a mid level factotum who uses his daily spells on all hours/level buffs with a lesser metamagic wand of extend to make them virtually all day. how strict would you guys be on the "cannot take 10" on UMD. I know that's what it says in the book. But to me (and this may just be because it doesn't favor me) it seems that it's a formality if it's simply a fire and forget every morning. why bother?

I think the only big thing is that if you get a nat 1 which doesn't pass the check, bad things happen, so you're saving yourself that misfortune by taking 10. If it's fire-and-forget, then each session just roll a bunch of UMD checks and take care of it then and there.

What are you using UMD for anyway? As far as I'm aware, the metamagic rods don't need it.

crap, it's a rod. my bad...
