For those having trouble with the Summer Totem:
I searched all over the internet for ways to finish this quest due to the Summer totem being a complete pain. Hopefully I can save some of you the hassle that I went through to find a result. For those people who didn't put any points into pyrokinetic (like me) to use Laser Ray (as stated above), fear not. You can create the laser ray scroll using sheet of paper+high quality fire essence+nails according to the DoS2 wiki. For those of you who don't have a high quality fire essence (like me), there is a wand for sale by a dwarf vendor at Driftwood, he was in between the smelly fish vendor and the enchantress(lady who sells scrolls/skill books). The wand is a named weapon - Chamore Doran - and is only level 9, or I believe that's the level I first came upon it so naturally its stats stayed at level 9. However, the skill that it offers is called "Vaporise" which will make a cloud of most, if not all, elemental surfaces. It requires a level 12 intelligence to use but if you took Loshe, or have a caster in the group, this shouldnt be too hard to come by. Shoot a fire arrow or cast a fire spell on the ground to set it ablaze next to the summer totem, then use the wand skill to make the fire surface into a fire cloud. This SHOULD automatically set the next part of the quest into motion, but be careful because if the wand is equipped when the next stage of the quest begins, you won't be able to change back to your original weapon in combat (at least not for me). Hope this helped, and good luck.
P.S. - The wand was pretty hefty in price for being a one time use, even with a 4 in bartering, so I would assume creating the scroll would be the cheaper option. But if money isnt an object for you, by all means, the wand is the better route than farming around for mats. You can also split one of your party members from the group, fast travel to driftwood square, buy the wand, then pyramid back to the party.
