40 agility on level 8 ? That's (without bonus to Agility via charm or equipment) 25 points = 5 times of a level up spended on agility. Rest 3 level ups (15 points) to reach level 8: on which stats do you spend these 15 points ?
Do not forget investing at least points in Constitution !
And don't forget that the Survivor can do that "Special Move" that is called "Sneaking" so the enemies mostly see you only if you walk nearby them ... A very handy special move!
I mostly start first with points in Constitution, then later in other stats. My survivor is now level 7 and her Const. is at least 25 .
It's a good idea to invest early on 1 point in Alchemy skill so you can combine small potions of mana + health to make a small Restoration potion (healing MP & HP at the same time!), always more and better than drinking 1 HP & 1 MP potion ...
Solving a quest in Aleroth healing 2 soldiers, have you done that ? If so, go talk to Goemoe and you learn for free one level of the Restoration skill so you can use that to heal fast !
O, and never think you're forced to do something in DD ... explore & find new ways to take XP points, new quests, new ways to discover more vendors to buy better gear if needed, etc ....
Hope this info can do a thing or two
PS: 73% chance to hit a
level 8 monster ... but an Elite Orc is of a higher level, maybe 15 or more I believe ! Not sure, but then that "73 %" can mislead you ! No ?
