Thanks for the idea!!
I played stone walls to lock up sniper instead of put stone walls near enemy to block them today
and a close-won over my friend's aggro Big-badass BM
locked-up watchtower and sniper and archer in (0,0) in first 2 rounds
(angels gonna work better than archer in walls,cause watchtower only provide indirect ability once per turn)
a temple at (1,1) plus priest hanging outside to daze/stun/tanglevine creatures
and sniper just keep on shooting aggro BM
used Bin-Shalla to help ToL
(cheap,and MINOR heal :S. Priest is the only one outside,malee +1 doesn't help at all)
a lay hand helps me survive longer
and a teleport to pull BM in front of sniper gaves him a last shot
(I was gonna bite to death next turn )
might try teleport binding on mage wand for sniper next time
evil huh?
and i am thinking of make a 1X3 or 2X3 stone wall coverage
despite watchtower have a zone exclusive and non-neighbor limitation
2 or 3 watchtowers still enough to give archers/snipers a happy hunting
an aggro-gunline?
