You misunderstood me :) SA is one thing - +125% permanent damage is quite a lot :eek: - SA is one of the best for the Elves (only surpassed by Unrelenting Force :D :D :D ...just kidding, Omniscience is the best for mages :) ) - and the racial ability, i.e., Avenger, is rare and may only be useful in the endgame (and deals decent damage only with Anven). IMHO, it's not effective.

Really? What about Sinedruds + Cursed + Spell + Rain (one volley from half the army wipes out the enemy thanks to Cursed, and Anven isn't even needed here)? It was a bad ability before, when improved and unimproved creatures were separated.
And the SA for Elves actually gives a smaller bonus, because luck is already being increased before the ability is reached, which already increases damage. For example, with 5 luck (everyone visits the luck-boosting locations before the endgame, and there are also artifacts) - the damage is 150%, with the Elven ability it's about 170%. So, the increase is only about 30% of what you already have from the Elven ability, the difference is that it reduces uncertainty, which is very good and will actually have a greater effect than 30% (and the opponent may also have an artifact that reduces luck), despite the simple math.
