THAC0 progression stops at the fighter's equivalent level 20 (it's a certain exp value) so the base THAC0 for a high level bard is always 10.

SPOILERS:


lowering THAC0 comes in the form of strength enhancments (the crom, or a strength belt so you can keep your longswords). there is a sword in ToB that will up your strength if you're going to the expansion. There are two sets of gauntlets that lower your THAC0 in SoA, so you can use one of those. Is you stick to longswords you will only get +3 THAC0 from any longsword in SoA, but it all counts. There is an ioun stone that lowers THAC0 as well as the helm that you get at the start of the game. However, with stoneskin, the fireshields, the protection from normal and magical weapons and the other magical enhancements the bard has, THAC0 should not be a big issue as you can protect yourself for rounds at a time, thus giving you loads of time to bash away.

you can also have a mislead clone sing the bard song for the bonuses there. and the cleric spells chant and bless are not to be overlooked
