Small, but sometimes important, tactical tricks.

Sorry if this is old news. There's a great trick for dealing with any tough unit in the dark dungeons. You'll need as many Fury stacks as possible (even just one unit per stack) and as many Lizard Riders as possible. It's known that Riders help units in attack. These units have good speed and initiative, so the speed of eliminating the enemy is quite high. So, move the Riders towards the target for elimination (without attacking, if there are too many enemies, just place them on an adjacent cell) and start attacking the mob with the Furies; each attack is accompanied by help from the Riders. And voila, all attacks on the enemy are unanswered. This tactic works very well against neutral creatures, as they are quite clumsy in combat. With humans, you need to use it with caution, of course. Good luck to everyone.

Oh yes, some may not know. If you attack with Furies while holding down Ctrl, they won't return, but will remain at the attack point.
