i came to sol c to do the hunter achievement. did a full clear and 0 rares were up. within 4 hours i had all of them done except gigantic ashwalker. with locs posted here and a loc marked on my map ive focused on those areas wile periodically clearing every other known beetle spawn point. im on day 4 with no ashwalker, i brought a ranger in to make sure i wasnt missing a spawn some were. the 2 confirmed spawn locations were cleared consistently for 10-12 hours a day and occasional clears of all other beetles. ive probably killed most of the other rares 2-4 times each in my efforts to find all the beetle spawns
Was an easy mob. Bit hard to slow at first as his mr is pretty high. Hits upwards of high 500's 600ish .. can't remember exactly. Straight up melee fight. He dropped the mask for us. To get him to spawn as you come in from sol a. We cleared the first room. Then cleared the mobs on bridge area and the beetles. Then cleared the lava elementals, oozes, and imps on right side tunnel and pulled back from bridge and kept that area cleared. Had both this mob spawn under the bridge and the protector of fire in dead end area with 4 spawn of fire elemental on 2nd round. Good luck.
It aggroed us when we were were clearing from sol-a side inwards. We had went right at the first split, then left into a large chamber with an axe swinging from the ceiling(like sol-a's swinging axe). On top was a crusader and marauder on the platform, hidden in the lava though were several crawlers including this one. They didn't aggro until we took a peak towards the elementals on the right side guarding the lava to the other half of the zone. The boots dropped for us.
