Ability damage/drain is giving me anxiety. How do you run it?
I'm DMing for a group of fairly casual players, and while they are definitely enjoying 3.5e, they're not really well versed in all the mechanics, and I tend to help them with their character sheets and builds basically. As our campaign progresses there's been more and more monsters I've been wanting to introduce, but many of them have character sheet altering effects like ability damage that while simple to understand require several numbers to be recalculated on the sheet (DEX alone would affect AC, touch AC, range attack rolls, reflex saves, all of the dex skills, etc.) Again, while this isn't hard to understand, it's book keeping, and it's amplified by the fact that my players don't really know the sheets well enough to erase and replace the numbers--or if they do it still slows the pace of the game a lot which they find unfun.
I've thought of replacing these types of statuses with others that provide similar but easier to manage effects, although I'm worried it'll break the balance somewhere in there.
So my question is, how do you run these types of effects without leading to constant updating of sheets over and over throughout the session?
P.S. this issue extends to other types of ability affecting conditions like exhaustion, entangled, etc.
EDIT: I should mention that we play on discord and their character sheets are PDFs (but not the auto-calculating kind)
