What's earliest level you can take out jaderfalas?

[Archaven]

Or there's a way to steal the Aldris blade early game?

[Waski]

On speedrun that You can find on YouTube guy is sneaking past and completely avoiding fight. So it's matter of having Rouge with high enough stealth if You really need it.

Edit. But it's on early version of the game, 1.0 I think.

You can steal his treasure if you can pass the enemies on the bridge (just before the cave entrance) because everything can be solved peacefully until then. High stealth and leap might be enough.

There are also some Xaurips and an ooze or 2 right as you enter the cave.  Not sure if you can sneak past them or not.

Or have a rogue and smoke veil out or scroll of withdraw.
