Love the lore, and this monster has been a new favorite of mine. I have a level 8 copy now, trying to go all the way. I've found the Way of the Cube is in fact power and victory by attrition.
p.s. signed up for the mailing list, and tell me where I can get one of those tight Monster snap-backs.
Void makes a huge difference at max level. No-ranged matches, it's very difficult for them to bust through, particularly if you bury your cube so deep it's grown from all the deaths before it starts taking damage.
