Doesn’t rely on Traits/Properties a lot, has multiple good melee options, has access to the very fun/strong repeater crossbow, the parry/stealth passive promotes skilled play, good boss damage.
But the double length stealth ability might be a bit too much, if required she can just run sooooo much, especially with the +10% movement speed talent. There are usually enough purple potions lying around that a committed Shade can get through anything that doesn’t require her to hold an area.
