I'm playing (3.24 & CBM 1.6) single player, on the Aran map, and have had to fall back on quite a few claymen, and am starting to look at Wooden Construction, both to take advantage of the 'buffed' constructs.
I also find a big stack of humble Pale Ones useful as all get out for sieges.
The moving of Attentive statues to Ench 0 and the introduction of stone hurlers opens up new possibilities for early exansion. You can now go with sloth 3 and expand with stone hurlers behind a few attentive statues.
Switch blood for death on your forge lord and take him awake, try to squeeze in nature. Pay for it with sloth 3 and drain 2. Use him to initially to research construction 2 and then crank out hammers and crystal sheilds.
When you reach construction 4 use your forge lord to offset your drain by forging skull mentors at 2 death gems a peice. Meanwhile your attentive statues protect you while you research evocation and enchantment. Earth readers with crystal sheilds spamming evocations behind statue and claymen front lines.
At Ench 5 you get marble oracles who are now down to 20 earth gems. Equip these using your reserve of hammers to make golden shields and frost brands and your forge lord makes them ethereal robes or wraith crowns (if you got cons 6) Also try to get gift of health up.
Then go alteration for iron bane, curse of stones and darkness which all has great synergy with your statues.
Baalz, how would you play MA Agartha in CBM 1.7, where blood stones are not available? Seems like CBM 1.7 really wrecks this strategy, and perhaps wrecks MA Agartha as well.
