By the way its ranger stealth, not ranger surprise. Ranger surprise reduce mob melee armro rating for short duration if I not mistaken. Yes its good skill for pulling mob without aggro the rest in the area.
Indeed, it's Ranger Stealth! And I use it! Great skill, 1 or 3 points in it is for me good enough. But I have also 1 points in ranger Strength from "David's Gauntlets" (side-quest in Brocken Valley Village).
But I'm not sure his Gauntlets are randomly or not, but their are god for a Ranger, for sure.
In fact, Ranger Stealth is also handy to fast focus on an enemy (with a bow!) BEFORE they see you and on that moment you can also use a spell like Magic Blast or Magic Missile, etc! But attention: some enemies have a very good sigth, others less... ! So 1 points isn't always enough if you wish to be the first that attack!

There are many ways to kill enemies, for sure

... but some kind of enemies are better I run and jump close to them and give them a great kick with a higher damage sword! (I found different good 2 handed swords at the beginning of the game: search for a sword with the name 'Flamberge' in it
Now on level 11 I'm using a Flamberge with a damage max of 50!).
With NO use of healing potions I kill without problems a enemy that is 2 or 3 levels higher!
But I must say, Magic Blast is very good and strong! It using much more Mana than for example Magic Missile and has also a long(er) cooldown time, but it's more than worth to spend at least 1 or 2 points in it in the beginning of the game if you choose to play as a mage too (for so far you can choose a point in this skill, it have some "required level", like all skills

).
I know you can choose Ranger Stealth after reaching level 8 and Magic Blast I think after becomes level 5 or 6. And this time I spend not immediately all skillpoints ... I left at least 1 or 2 points and use them if realy necessary!
If you want a good Talisman (Amulet) early in the game - I got it if I was at least level 7 or 8 I believe ... :
go to the Delerect Tunnels (have 3 hatches - one is nearby the Waypoint Shrine 'Tribal Shrine' (Brocken Valley)) + "Secret Passage" ... to gather 3 Talismans: 1 from West, 1 from the East and 1 from the South. Find also a book that give clues ("Tomb Note" I think that book is named, finding on the place where you can use the Talismans the second time!). But you can first also using the Talismans somewhere else!!: in the Secret Passage by the 'Chapel Shrine' (Brocken Valley) you can find a place in that dungeon where animal pelts laying in a half circle around a throne-chair. Stay near the chair and try to "use" some Talismans. Don't be afraid, you should NOT dying, even if you try more than once!! But be sure killing first all enemies in this place. So go FIRST to that throne and after that, go to the other place (you found that book Dusty Tomb!). Tip: I place 4 markers on the place where I find that book and see 2 statues and plants.
The Talisman or amulet you gather after searching how to find him is a good one, but also randomly I think! But mine amulet has 3 empty enchantmentslots(!), 1 empty charmslot, 2 points in wisdom(!) and also 1 thing more, I can't remember now...
