This question is directed towards data nerds like zeddy and krakky, but anyone can answer them really.
-What's the difference in power for example a level 1 acheron and a level 10 one?
-Does heating matter in LD? Since you always see "random player is wielding random weapon level 1".
-Is it possible to gain prestige via LD?
What's the difference in power for example a level 1 acheron and a level 10 one?
Between level 1 and level 10 ★★★★★ items is pretty ridiculous, I think it's about a 25% raw damage increase. Which is even greater when you factor in defenses. (Compare 100 - 40 with 125 - 40)
Is it possible to gain prestige via LD?
Uh, no? Where'd you get this idea from?
