Stealth I is the first of three Stealth stat boosts. It opens at level 2 and suits players who prefer to stay unseen.
Stealth I sits at position 11 of 19 in the Stealth tree. Unlocking Stealth I takes 2 skill points. You need level 2 before you can buy it. Jacob and Evie each have their own skill tree, so you buy Stealth I once for each twin.
