Here's a short list of achievements that cannot currently be attained in the game due to bugs or oversight:
Almost - Kill a monster with your orb that would otherwise destroy your orb Orb damage was removed in a recent patch
Flea Trap - Kill 45 cursed monsters with your orb Orb danage was removed in a recent patch
Put the Lights Out - Gain 500 xp from destroying beacons Beacon XP does not increase the counter for this achievement
Bone Shredder - Kill 600 monsters before wave 12 starts The bar counts up, then keeps counting past 600 without awarding you the achievement
Stormy Weather - Have the beacon storm trait set to Level 7 at field N7 N7 does not exist, probably due to the bug with the third compass reward
Lockpick O4 - Destroy all wizard locks at field O4 before wave 18 starts O4 does not have wizard locks. O6 does, but doing this in O6 does not award the achivement
Bone Shredder - Kill 600 monsters before wave 12 starts Under Pressure - Shoot down 340 shadow projectiles
I got these achievements yesterday..
How to get Super gem/Hyper Gem/Wicked Gem? "Create a grade 3 gem with 300 raw max damage" I've created grade 3 gem with 114-360 damage and nothing happens
Under Pressure is at least bugged for version 1.06. I have confirmed this with three other testers.
Super/Hyper/Wicked is based upon the BASE damage, before skills/etc are taken into account. Using a gem enhancement shrine or "supergemming" (combining gems two levels lower to increase the damage but not level) are what most people did.
Have anyone acquire "Artisan traper"? Description say - kill every monster with gems in traps. I ran F1 and killed every monster with traps, but did not get this achivement.
