ToME: the Tales of Maj'Eyal

So I've been using 2 Rings of Blinding strikes for about 20 levels for their damage buffs, but have no idea how the blinding mechanic works,along the same line I have a weapon with 49% acid blind. Can someone give me an idea of the mechanics behind such effects?

It's hard to give a general description, because most of these effects are case by case.

The 'blinding' damage type, is a percent chance to try to be applied, and is checked with your spellpower. So '+10 blinding' means every hit has a 10% chance to try to blind, which then tests your spellpower vs. their physical save. Most other status effect damage types work in a similar way. For instance, gloom damage is a percent chance to activate, but doesn't make a save check.

The other big category is the status effect damage types, like acid blind, lightning daze, and ice. In general, these deal normal damage and then have a flat 25% chance to apply the status effect, which may or may not allow a save. So a weapon with 49% acid blind would have 49% of its damage converted to acid, and have a 25% to try to blind (testing the highest of your spellpower or mindpower against their physical save).

In the next release, a lot of the descriptions are being made more clear, and a lot of the effects are being made to use the highest of several powers to use against the target's save (In general, the highest of Accuracy/Mindpower/Spellpower).

Thanks a bunch, that's very helpful. Seems like I should have replaced the rings long ago.
