I must say, my strategy, for me, works fine

.
My favorite pasive skills in battle are:
1) "Stealth" (Ranger) give me more "sight"! Very good to see an enemie (the most of them) BEFORE they see me!
2) "Confusion" (Mage) give me "more time" to change between Magic Missile and using the bow :
while enemies are confusted when I attack they with a spell (most of all Magic Missile), I begin shooting with my bow (a very good on this moment!) and change whole time between bow and MM-spell

, but, if the enemies coms to close (some are very fast runners!),
3) I use skill "Wirlwind" and run a little away if to much enemies surrounds me or an enimy is to strong for only slash him with a sword or mace/hammer/axe ...
4)also the skill "Destruction" give my spells more damage!
My active skills I used most are on this moment:
1)Magic Missile, 3 points in it
2)Summon Undead, 1 point (give me also more time because of enemies attack first or also the undead)
3)Fireball, but not so much, 1 point
4)Magic Blast, 2 points
And I try to make my equipment whole time better and also search for good enchantments and charms.
Furthermore I forget probable things to say ... continued
A question:
who used "potions" for 180 sec more Strength or more Dextery or more Resistance?
