ToME: the Tales of Maj'Eyal

I see weapons with a stat Accuracy bonus. xx/acc. is that the 'overflow' i hear around? as much as i try, cant find it in forum or on wiki. and is that just the excess accuracy?

edit: and does negative armour mean the enemies take extra damage?

Armor ends at 0.

I think it's accuracy over defense that has the bonus values but I haven't actually looked.

Have seen enemies with negative armour... (after debuffing them)

Armour below 0 has no special effect.

It is your accuracy above the target's defense for those bonuses.
