For this run, like you can see, it's just running like a tard the 2/3 of the game ^^' , and for some boss you have to fight, there are little tricks to beat them without damage :

• For the spider, you have to beat her with a good bow, and be in mi-distance, there is a distance, or she attack you with cac, but we're too far for getting hit.
• for the robot gobelin, it's quite complicated : you have to attract him to the pipe like the vid, be at the opposite, like that, normally he's stuck. You also need firespray spell (and lvl 4 with this magic), and don't touch him directly. If you do that, he react, and you die instant. Hit with the right buttom of your mouse behind him (the sword must be not red), and be patient ^^. You also need a little of potions of mana of course. It's a tricky thing to do, i was very lucky in the vid.
• Before to fight gresh, you have to xp (with acid gas is better for AOE i think), near the resurect statue, for getting resurrect. When you're approximatively lvl 20-25, you can beat gresh and continue. At this point, be sure to get the "fire ring" to continue, and xp until lvl 26 (for to get that spell). You can use the spell, dying (but getting a LOT of xp every spell you use ^^), and continue. When you resurect, use your spell, die, and continue, until Gom. For Gom, it can be a little difficult, a good invocation may help. Be sure to not dying if possible, his regen is really fast. Spam spells, invocs, potions of mana and heal at the best moments, and pray :p .
