For some reason (old age no doubt), I convinced myself that the 1e Virtue, the Speakers, was still in TOR2e. (In the earlier game it's a pretty niche Virtue, but it has come in handy inside a dungeon crawl, or exploring ruins etc; particularly when other Common Skills came up short.)
So I looked at Luminescence to help with the exploring. Elsewhere this enchantment has already been described as a pretty feeble bonus in gaming terms. This seems wrong to me: when you look at the impact of "Beater and Biter" on the goblins in the tunnel, it is so much more than merely glowing in the dark like a candle.
And then we see the Virtue, Gleam of Wrath. That description is of internal Elvish spirit/fury somehow powering a weapon to drain Hate with every blow. (Fair enough: another magic quality: where that Elvish affinity/skill with material objects enhances a pyschological effect on their enemies.) But is this not the essence of Beater and Biter (Glamdring and Orcrist)? And the pyschological effect of their blue light - their coincidental Luminescence - is the manifestation of Gleam of Wrath.
So, is Luminescence an unnecessary enchantment? Or is Gleam of Wrath actually wrongly labelled as a Virtue, when it should be an enchantment for Elvish weapons forged in the First Age (i.e. from Gondolin).
