I have a +3 spear, a +2 ring of accuracy, and 5 scrolls of upgrade. I have been waiting for a nicer weapon to update, but now that I have found this ring I wonder if I would be better off just enchating the ring, saving 2 enchantments for allowing me to wield a +0 glaive or +0 hammer, should I ever find one.
Unfortunately it’s hard to compare better damage (by upgrading a weapon) vs. better accuracy (by upgrading the ring), as it depends on many factors, including the fought enemy.
However as the ring accuracy bonus is exponential (1.4totalAccuracyBonus) while the weapon damage bonus is linear only, as a rule of thumb I’d say that it’d be better to mass upgrade the ring (but maybe am I wrong!)
About the saving scrolls -- my strength is currently inadequate for a +0 glaive or +0 hammer so I was planning to upgrade it -- assuming I ever find one, of course. The nice thing about using the scrolls on the ring is that my +3 spear could get the benefit as well until I find something better. And killing cave spinners is getting tough with just a spear ...
